        <content:encoded><![CDATA[<p>What do today’s pastors think about science? &nbsp; What views do they hold on creation and evolution and how strongly do they hold them? &nbsp; How do origins issues impact their ministries?</p>

<p>These were just a few of the questions that motivated us at BioLogos to commission a survey of pastors on origins. &nbsp;In 2012, the Barna Group conducted 743 telephone interviews with pastors from across the US, from churches big and small, and from all Christian denominations. &nbsp;This comprehensive, in-depth survey provides a fascinating analysis of views held by clergy today. &nbsp; In the coming month, we’ll be digging deeper into the survey results, but for now, here are some key highlights:</p>

<h3>#1: Pastors hold a diversity of views on origins.</h3>

<p class="caption-center"><img alt="" src="http://biologos.org/uploads/static-content/clergy_views_chart.jpg" /></p>

<p>Overall, while a slight majority of the pastors surveyed fall under the label of Young Earth Creationism (54%), sizeable portions of clergy accept Progressive Creation (15%) and Theistic Evolution (18%).</p>

<p>The numbers varied widely based on a number of factors, however. Pastors of mainline churches were most likely to accept Theistic Evolution, while non-Mainline, Charismatic, and Southern Baptist pastors were overwhelmingly Young Earth Creationists. Pastors of larger churches were also more likely to accept Theistic Evolution.</p>

<p>Regionally, the highest percentage of YEC pastors was found in South, while the highest percentage of pastors accepting TE was in the Midwest. Pastors from the western states were the least likely to accept TE.</p>

<h3>#2: Most pastors think science and faith questions are important.</h3>

<p>Regardless of their views, the majority of pastors surveyed feel that the Church needs to look at how it handles issues of science. 72% of pastors with YEC views and 73% of pastors with TE views agree with the statement that <em>“the Christian community needs to take a serious look at its understanding of science and human origins in order to maintain its witness in the world.”&nbsp;</em>(The numbers are slightly lower for pastors who hold to Progressive Creation and who are uncertain).</p>

<p>Similarly, 66% of YEC pastors and 61% of both TE and Progressive Creation pastors agree that <em>“younger adults today are more concerned than ever about whether faith and science are compatible.”</em></p>

<h3>#3: Clergy think disagreements on science and faith harm our witness (but for different reasons).</h3>

<p>Clergy across all three viewpoints feel that disagreements are harming the Church’s outreach, but they differ in how they view that harm.</p>

<p>YEC pastors overwhelming agreed (85%) that <em>“Christian disagreement on matters of creation and evolution is compromising our witness to the world.”</em> However, a majority of TE pastors disagreed with the statement (63%).</p>

<p>Conversely, a majority of TE pastors (63%) agreed that <em>“The church’s posture toward science prevents many non-Christians from accepting Christianity,”</em>&nbsp;while a majority of YEC and Progressive Creation leaning pastors disagreed (59%).</p>

<h3>#4: Pastors aren’t avoiding science.</h3>

<p>The majority of pastors think that addressing issues of science for their congregations is an important part of their work. Of those surveyed, 72% felt that addressing science issues in the local community was somewhat (51%) or very (21%) urgent. When asked about science on a national and global level, even more pastors felt that addressing science issues is important (43% somewhat and 46% very). Furthermore, 79% of pastors included scientific themes in at least one sermon in the past year, and 40% had included them in at least ten sermons.</p>

<p>The majority of clergy across all four viewpoints also agreed with the statement <em>“Just as scripture should influence human interpretation of science, science should also inform our understanding of scripture.”</em> The numbers were highest for TE pastors and those who are uncertain (81% and 72%, respectively), though over half of YEC and PC pastors also agreed (52% and 65%, respectively).</p>

<p>Finally, although YEC’s are more reluctant than other pastors to say “science should inform understanding of scripture, they strongly agree (84%) that <em>“The Christian community needs a greater commitment to showing how young earth creationism is consistent with science.”</em></p>

<h3>#5: However, they are concerned about evolution for biblical reasons.</h3>

<p>Over half of pastors said they had “major concerns” about the idea that God used evolution. The main reasons for that concern were that the idea “undermines the authority of Scripture” (64%), “views portions of the Bible as non-literal, like Genesis” (62%), “raises doubts about a historical Adam and Eve” (61%), and “raises questions about how and when death and sin entered the world” (59%). However, 26% of pastors saw no concern with the idea that God used evolution.</p>

<h3>#6: The majority of clergy accept parts of scripture as symbolic.</h3>

<p>60% of the pastors surveyed felt that “some portions of the Bible are symbolic, but all that it teaches is authoritative.” Clergy whose views fall under theistic evolution and progressive creation were more likely to accept this statement (79% and 73% respectively), but a sizeable number of YEC pastors (40% among the core followers and 49% among those leaning towards YEC) also agreed with the statement.</p>

<h3>#7: Clergy are concerned that changing their views on origins might compromise their ministry.</h3>

<p>Over half of pastors (58%) who fell under the YEC category agreed that <em>“If you publicly admitted your own doubts about human origins, you feel you would have a lot to lose in your ministry.”</em> 41% of pastors in the Progressive Creation group also agreed with the statement. Pastors who were uncertain or who fell under the Theistic Evolution group were less concerned, with only 26% and 17% respectively agreeing with the statement.</p>

        <title>A Scientific Commentary on Genesis 7:11</title>
        <link>http://biologos.org/blog/a&#45;scientific&#45;commentary&#45;on&#45;genesis&#45;711?utm_source=RSS_Feed&amp;utm_medium=RSS&amp;utm_campaign=RSS_Syndication</link>

        <description>Although committed to the principle of sola Scriptura, Calvin recognized that the Bible would have been written in terms its original recipients would have understood. Calvin inherited the medieval cosmology of his time, a way of viewing the world heavily influenced by Greek thought and one which was about to receive shocks from astronomers such as Copernicus and Galileo. But not just yet.</description>
        <content:encoded><![CDATA[<p><strong>Genesis 7:11</strong>: In the six hundredth year of Noah's life, in the second month, on the seventeenth day of the month, on that day all the fountains of the great deep burst forth, and the windows of the heavens were opened.</p>

<p><strong>Genesis 8:1</strong>: But God remembered Noah and all the wild animals and all the domestic animals that were with him in the ark. And God made a wind blow over the earth, and the waters subsided; 2 the fountains of the deep and the windows of the heavens were closed, the rain from the heavens was restrained, 3 and the waters gradually receded from the earth.</p>

<hr />

<p>The Flood narrative of Genesis 7-9 has played a prominent role in science and religion debates for over three hundred years and gave rise in earlier centuries to geological theories such as old earth catastrophism. While literary studies have uncovered the chiastic structure of the Flood story (see Gordon Wenham, “The Coherence of the Flood Narrative” Vetus Testamentum 28 (1978):336-48) and with it the theological pivot point of the entire narrative (Gen. 8:1 – “And God remembered Noah…), much of the popular attention remains on the questions regarding details (Is there THAT much water in the world to cover ALL the mountains to a depth of 15 cubits? Could you really fit two or seven of every animal species in an ark that size?) </p>

<p>Looking at a smaller matter, we find at the beginning and the middle of the narrative indications of an ancient Near Eastern worldview. As the story is told, the flood was not merely the result of excessive rain, but actually the convergence of the waters above the earth with the waters below the earth. It is, as one translation puts it, as if the sluice gates at the deep and of the heavens were thrown open and water poured in from above and below. This is a consistent picture from the Old Testament of a three-tiered universe—a dome above the earth holding back the heavenly waters, a flat earth with water on its surface, and water under an earth which is held up by pillars. </p>

<p>That the story is told using the cosmology of its time should not be unduly unsettling, nor that the story is reinterpreted as new understandings of the universe come into favor. By way of example, consider John Calvin and his understanding of the structure of the universe. Although committed to the principle of sola Scriptura, Calvin recognized that the Bible would have been written in terms its original recipients would have understood.   </p>

<p>Calvin inherited the medieval cosmology of his time, a way of viewing the world heavily influenced by Greek thought and one which was about to receive shocks from astronomers such as Copernicus and Galileo. But not just yet. Calvin still subscribed to the common conception of his day in which the four elements—earth, air, fire, and water—comprised the earthly sphere and possessed unique characteristics. The nature of air and fire was to rise, while the nature of earth and water is to sink.  Earth, being heavier than water, should sink to the center of the cosmos and water should compose the next layer. Both earth and water are spherical, i.e., naturally form spherically around the cosmic center. Thus the heavier spherical element of earth should be encased entirely within the lighter spherical element of water.</p>

<p>Notice what this does to the flood story. For Calvin, the amazing thing is that the world isn’t constantly under water and subject to flooding. In the cosmology of Calvin’s day, it does not take an act of God to cause a universal flood, but rather an actively present and restraining hand of God to keep the waters back in everyday circumstances and make inundation by water something other than universal. </p>

<p>Obviously, Calvin was wrong. Or perhaps we should say that medieval cosmology was flawed and justifiably gave way to new conceptions of the universe. The answer is not to return to an ancient Near Eastern cosmology, but to reinterpret cautiously within new and better cosmologies and to pay closest attention to the text and the theology of scripture.  </p>

<p>The geological and planetary sciences bring their own unique contributions and are of more interest than the latest expedition to discover the ark on Mt. Ararat. Is the flood story a universalization of a catastrophic regional event that burned itself into the psyche of ancient cultures in the Mediterranean basin? Various theories regarding a Black Sea venue for a catastrophic flood event are still in process of being sorted out. It’s intriguing. Or the question where the water on Planet Earth comes from? Was it always here as an emanation of vapors from the earth’s crust in its early formation, or has it accumulated over eons through the steady bombardment of earth by small, icy comets? It’s an intriguing scientific question that is in the midst of determination through testing.</p>

<h3>Preaching Suggestions</h3>

<p>When preaching on the story of the Flood, it is easy to get lost in the debates over particulars. As mentioned elsewhere, to tackle all the peripheral issues threatens to turn a sermon into a geology lecture. Other settings are better suited to addressing those questions, and those are best addressed open-endedly. </p>

<p>A brief explanation of ancient Near Eastern cosmology can be helpful to contextualize the story. If there are those who are tempted to think that a cosmology embedded in the Bible must be inspired and definitive, one can note that cosmology has changed by the New Testament. The Bible itself isn’t wed to a particular structure of the universe. </p>

<p>What is important is to keep the theology of the text front and center, and in that theology there are at least three non-negotiables from the flood narrative. First, human sin and violence threatens to undo a good creation (the flood is a de-creation event, a return of the waters mentioned in Genesis 1:2). Second, God remembers Noah, and never forgets his promises. Third, the end of the flood is a covenant with the whole earth regarding the stability and endurance of the natural order.

        <title>Dissonance and Harmony</title>

        <description>People hold clearly discordant points of view, and it would be dishonest to ignore the conflict. Yet some voices emphasize the dissonance without any note of harmony to put it in context. Too often, science and faith becomes a hostile battle of worldviews, sounding angry, dissonant chords even among fellow Christians. But civil, gracious dialogue is possible.</description>
        <content:encoded><![CDATA[<p>As soon as my older brother began piano lessons, I begged to play the piano too. My parents decided to let me try, which led to cute pictures of a 4-year-old climbing up onto the piano bench at her first recital. Like all young students, I started with scales and simple pieces, but over the years, my love for music deepened and matured. My piano teachers showed me that a beautiful concluding chord was often preceded by a dissonant clash. Dissonances sound harsh by themselves, but without them, music would sound boring and trite. If I rushed past the dissonance, the final resolution was not as beautiful. Instead, I learned to pause on the dissonant notes, to carefully place them in the context of the surrounding harmonious chords. The dissonance and harmony together formed more beautiful music than either alone.</p>

<p>Conversations about science and faith can be like that. People hold clearly discordant points of view, and it would be dishonest to ignore the conflict. Yet some voices emphasize the dissonance without any note of harmony to put it in context. Too often, science and faith becomes a hostile battle of worldviews, sounding angry, dissonant chords even among fellow Christians. But civil, gracious dialogue is possible. On the BioLogos Forum, we invite authors from a range of positions, including some that don't agree with all our <a href="/about">beliefs</a>, but we strive to set these dialogues in a context of respect and civility. When authors are fellow Christians, we don’t shy away from disagreements, but remember the broader context of our unity as fellow believers, the harmony that binds us together.</p>

<p>My own story is more harmonious than dissonant. My interest in music was paralleled by my interest in math and science and my involvement in church. My family and teachers encouraged my interests in science, and I remember how fun it was to play math games with my dad and brother. And every week we were in church: twice on Sunday, plus Wednesday night club, youth group activities, and Bible quizzing. While my church accepted the young earth position, they didn’t emphasize it, and I was never told that a particular science view was essential to being a Christian. When I encountered the evidence for the age of the universe and the evolution of life, I also found Christian authors who showed me how this scientific evidence could fit with Christian beliefs.</p>

<p>But others have experienced more dissonance. Nearly four years ago, Dr. Francis Collins launched this website with the story of a young university student in the midst of a profound personal crisis, what Dr. Collins called “a wrenching crisis of worldviews shaking her deepest foundations.” Without a context of harmony, too many people – young and old – feel they have to choose between two incompatible positions, either Christian faith or the findings of science. BioLogos exists to show another way. We hold fast to the authority of the Bible and the core beliefs of Christianity, and at the same time, accept the rigorous conclusions of mainstream science.</p>

<p>It is with these chords of dissonance and resolution in mind that I come to this opportunity to lead BioLogos. I have long sensed God’s calling to serve the church as part of this dialogue. Some of you know of me from a book I wrote in 2007 with my husband Loren, called <em>Origins</em>. I’ve been speaking and writing on science and faith for many years, but I did this around the edges of my primary career of teaching and research in astronomy. While I thoroughly enjoy teaching students and doing research, over the last year I have recognized God’s hand in leading me to shift my fulltime work to the science and faith dialogue. Now I’m looking forward to using and developing my gifts in service of BioLogos.</p>

<p>Joining me as a new member of the leadership team is Dr. Jeff Schloss, who will serve as our Senior Scholar. Many of you are already familiar with his work, and know he brings not only a strong track record of scholarship in evolution and philosophy, but tremendous skill in communicating to lay audiences. Jeff and I share a deep commitment to the unity of the body of Christ and a desire to remove barriers for people to come to Christ. I am delighted to have him on board.</p>

<p>Jeff and I inherit a strong and vibrant organization from our outgoing President, Dr. Darrel Falk. Darrel brought his deep love and concern for the church, along with his considerable creativity and hard work, to this effort. We plan to continue and build on the excellent programs he established.</p>

<p>One of the pleasures of my first few weeks on the job has been getting to know the BioLogos staff. Kathryn, Lisa, Stephen, Mike, Laura J, and LeAnne each bring key skills to the organization, as well as energy and a passion for the mission of BioLogos. The team keeps BioLogos functioning behind the scenes, from finances to computer programming to event planning. Two team members, Mark Sprinkle and Tom Burnett, have decided to move on to other opportunities after a year of dedicated service to BioLogos. As web editors, Mark and Tom revamped the blog, making it a forum for rich scholarly dialogue and vibrant testimonies, and drawing in new authors to write on a great mix of topics. They also organized the archived material, so that the best of BioLogos is readily accessible. We wish them well in their new endeavors. Joining the BioLogos team is Emily Ruppel as Interim Web Editor. You may know Emily from her work to develop and edit the e-zine God &amp; Nature for the American Scientific Affiliation; she will join us part time at BioLogos while she continues to work with ASA.</p>

<p>We believe God has great things in store for BioLogos. We will continue to focus on connecting with scholars, pastors, teachers, and lay people, but in the months ahead, we will also be sharpening our vision and engaging afresh in strategic planning. We’ll be considering new audiences, new programs, and new priorities. I invite your comments below on directions you’d like to see BioLogos take.</p>

<p>In just a few years, this organization has impacted the lives of thousands of Christians and brought an important voice to discussions taking place within the church. Thanks to the strong support from The John Templeton Foundation and many other generous donors, the vision of Francis Collins is thriving. BioLogos is on the cusp of enormous opportunities and huge potential. While transitions are times of risk and vulnerability, they are also times of great opportunity. My prayer is that God will give us wisdom and guidance to be good stewards of this opportunity. May God continue to use BioLogos to bring harmony to a conversation that has emphasized dissonance for far too long.</p>

        <title>Science and the Bible: Assessing the Evangelical Encounter with Evolution</title>

        <content:encoded><![CDATA[<p>Having now completed our study of the five main views about “Science and the Bible” held by conservative Protestants, I conclude with a final column, assessing the whole situation as I see it today. </p>

<p>For more than a century, evangelicals and fundamentalists have typically rejected both evolution and higher biblical criticism. Sometimes there are good reasons: the claims of some biblical scholars are so outrageous and the claims of some scientists so anti-religious, that a strongly negative response is entirely appropriate. Too often, however, the evangelical encounter with modern science conforms to what <a href=" http://www.youtube.com/watch?v=eQviXavl1BA">historian Mark Noll</a> has called “the scandal of the evangelical mind”—namely, “that there is not much of an evangelical mind.” Attitudes toward science have been crucial to this analysis. As Noll says, “since 1960 creationism has done more than any other issue except abortion to inflame the cultural warfare in American public life.” (p. 192) </p>

<p>Readers who want to know more about Noll’s book and its reception should go <a href="http://www.liberalevangelical.org/index.php?option=com_content&view=article&id=144:the-scandal-of-the-evangelical-mind-by-mark-noll&catid=68:reviews-recent-a-relevant&Itemid=123">here</a> and <a href="http://www.firstthings.com/article/2008/08/003-the-scandal-of-the-evangelical-mind-a-symposium-33">here</a>. His conclusions about evangelicals and science are fully consistent with those I am about to present.</p>

<h3>Evangelicals in Tension with Science</h3>

<p>Evangelicals exhibit <em><strong>considerable tension and ambivalence</strong></em> when it comes to science, especially human evolution. On the one hand, evangelicals enthusiastically embrace the findings of science, when it comes to most applications in medicine and engineering. They also accept the experimental sciences, such as physics, chemistry, physiology, or thermodynamics. They have no problems with gravitation, the periodic table, the circulation of the blood, or the law of entropy. Here, their attitude is highly empirical: if it can be shown from repeatable experiments and observations, it’s true and presents no challenge whatsoever to religious belief.</p>

<p>On the other hand, evangelicals are quite hesitant to accept some conclusions of the so-called historical sciences, such as geology, cosmology, and evolutionary biology. Fundamentalists reject the very legitimacy of those sciences, and have created their own alternative explanation, “creation science,” which comports with their particular views of biblical authority and hermeneutics. Evangelicals are more ambivalent. As we’ve seen, many evangelicals accept the big bang and modern geology, with a 4.65 billion-year-old earth and the enormously long history of living things before humans arrived on the planet. But evolution–understood here to mean the common descent of humans and other organisms–presents very serious problems for many, perhaps most, evangelicals. This motivates them to look for alternative views.  </p>

<p>The alternatives evangelicals embrace are precisely those we have studied in this series. Some eagerly support the YEC view. Others prefer one of the many varieties of the OEC view. Many like the strident tone of the ID movement, with its vigorous assault on biological and cultural “Darwinism” and its near-universal rejection of human evolution. For most evangelicals, however, TE is probably not a viable option at present, for biblical and theological reasons.</p>

<h3>Reconciling Evolution with Scripture</h3>

<p>Most evangelicals do not see any reasonable way to combine human evolution with the following beliefs:</p>

<ul><li>the uniqueness of humans, who alone bear the “image of God”</li>

<li>the fall of Adam and Eve, the original parents of all humans, from a sinless state, by their own free choices to disobey God</li>

<li>the responsibility of each person for their own actions and beliefs, within a universe that is not fully deterministic</li>

<li>the redemption of individual persons by the atoning sacrifice of Christ.</li></ul>

<p>Evangelicals cannot and must not be separated from these crucial beliefs about human dignity, freedom, responsibility, sin, and redemption. The 64-dollar question is: can these beliefs be maintained without simultaneously affirming the necessity of an historical, separately created first human pair? The answer is probably in the hands of evangelical academics, especially theologians and biblical scholars. Can they be persuaded that the scientific evidence for evolution is sufficiently strong to warrant a re-examination of the traditional view?  Can a credible gospel and credible science be harmonized?  </p>

<p>There exists an enormous gap between popular conceptions of science–conclusions, methods, and attitudes–and those of scientists themselves. This gap is not unique to science among practitioners of specialized knowledge, and it is not unique to evangelicals among the lay public.  But it is real and very significant, and it affects theologians and biblical scholars no less than anyone else. Those who try to bridge this gap are mostly scientists (in their role as educators at colleges and universities and insofar as they write books for lay readers) and science journalists.  Many influential members of those professional communities are skeptical or even strongly hostile toward Christian beliefs, and this can exacerbate an already difficult state of affairs. If ways can be found to popularize good science, while showing appropriate sensitivity to the concerns of evangelicals, it would be a very good thing.</p>

<h3>Signs of Hope</h3>

<p>Certainly there are reasons to hope.  The conversation about science and religion is considerably broader now than it was at the time of the Scopes trial in 1925. Back then, many Protestants faced a very grim choice. On the one hand, they could follow politician William Jennings Bryan and the fundamentalists, rejecting modern science in the name of biblical authority and orthodox beliefs. On the other hand, they could follow theologian Shailer Mathews and the modernists, rejecting biblical authority and orthodox beliefs in the name of modern science. There was no one out there like John Polkinghorne, Francis Collins, Joan Centrella, Owen Gingerich, Simon Conway Morris, William Phillips, or Ian Hutchinson—to name just a few of the many top scientists today who accept evolution while affirming the divinity of Jesus, the bodily resurrection, and the actual divine creation of the universe. But they are all scientists, not theologians (except for Polkinghorne, who is both). In Galileo’s day, it was the scientists who eventually convinced the theologians and biblical scholars to accept Copernicus’ theory of the earth’s motion around the sun. But, it took a long time, and the process was difficult and often painful. Thus far, the biblical scholars and theologians who have tried to move the conversation forward have not been very well received, as Richard Ostling has <a href="http://www.christianitytoday.com/ct/2011/june/historicaladam.html">so capably reported</a>. I suspect we are in for more of the same.</p>

<h3>It’s Your Turn to Talk</h3>
<p>That’s what I think. What do you think? I’ll mainly be listening quietly, since I’ve now said all I wanted to say. Thank you all for hanging in there for ten months—far longer than I had originally anticipated. After a short respite I’ll return with a new series, but I’ll keep the topic under wraps for the time being.</p>]]></content:encoded>

        <description>In this series, Mark Mann explores what many of the great Christian theologians and saints of the Church have said about how God speaks in and through God’s other great book: Nature, or Creation.  Listening to figures from the the 2nd to the 18th centuries,Mann proposes three main points: 
Christians should think of Scripture and Creation as two “books” that should be read together for understanding the fullness of God’s self&#45;revelation;
Science is a God&#45;given tool for discerning the handiwork of God in Creation, and is fully compatible with God’s Word revealed in Scripture, and therefore,
Christians have nothing to fear from science.</description>
        <content:encoded><![CDATA[<h3>Scripture and Creation</h3>

<p>Augustine had a great deal to say about those chapters in Genesis that are especially controversial within Christianity today. In fact, Augustine dedicated about as much as any other Christian writer to the first few chapters of Genesis, so there is little guesswork we have to do in ascertaining what he believed Scripture to claim about creation. First of all, Augustine clearly rejected the notion that God had created the earth in six 24-hours periods. Instead, he believed that the universe was created instantaneously, and that the six days reported in Genesis were a metaphor for the various levels of dimensions of the created realm—something akin to what ancients referred to as the ‘Great Chain of Being’. But this is not to say that Augustine believed that the world was created as it is today in that instant. Rather, he affirmed that God created the world with inchoate potential for further development, like an acorn that will grow into a great tree when planted in the ground. </p>

<p>Augustine therefore affirmed that Creation has evolved and continues to evolve, though not driven by random natural processes, as affirmed by classical Darwinism. Instead, such evolution is governed providentially both via the inchoate potentialities present in the world from its beginning and by God’s ongoing governance of the universe.<sup>4</sup>  We should be careful not to turn Augustine too quickly into a modern advocate of theistic evolution, but the similarities are nevertheless significant. Augustine affirmed these ideas not on the basis of an attempt to accommodate Scripture to scientific discovery, but based upon his own reading of Scripture! Indeed, I think it fair to say that the great father of Western Christianity was something of a proto-evolutionary theist, and therefore one whose work deserves far more attention by those seeking to be faithful to both Scripture and Christian tradition while making sense of the claims of contemporary science.</p>

<p>Of course, we need to be careful not to push such claims <em>too</em> far. Augustine himself resists such a move by recognizing both the contingency of human interpretations of Scripture and the dangers of unintentionally imposing our own views on Scripture. A rather long, but significant quote from Augustine makes this point all too clear:</p>

<blockquote>Let us suppose that in explaining the words, “And God said, ‘Let there be light,’ and light was made,” one man thinks that it was material light that was made, and another that it was spiritual. As to the actual existence of “spiritual light” in a spiritual creature, our faith leaves no doubt; as to the existence of material light, celestial or supercelestial, even existing before the heavens, a light which could have been followed by night, there will be nothing in such a supposition contrary to the faith until unerring truth gives the lie to it. And if that should happen, this teaching was never in Holy Scripture but was an opinion proposed by man in his ignorance.<br /><br />

On the other hand, if reason should prove that this opinion is unquestionably true, it will still be uncertain whether this sense was intended by the sacred writer when he used the words quoted above, or whether he meant something else no less true. And if the general drift of the passage shows that the sacred writer did not intend this teaching, the other, which he did intend, will not thereby be false; indeed, it will be true and more worth knowing. On the other hand, if the tenor of the words of Scripture does not militate against our taking this teaching as the mind of the writer, we shall still have to enquire whether he could not have meant something else besides. And if we find that he could have meant something else also, it will not be clear which of the two meanings he intended. And there is no difficulty if he is thought to have wished both interpretations if both are supported by clear indications in the context.<br /><br />

Usually, even a non-Christian knows something about the earth, the heavens, and the other elements of this world, about the motion and orbit of the stars and even their size and relative positions, about the predictable eclipses of the sun and moon, the cycles of the years and the seasons, about the kinds of animals, shrubs, stones, and so forth, and this knowledge he holds to as being certain from reason and experience. Now, it is a disgraceful and dangerous thing for an infidel to hear a Christian, presumably giving the meaning of Holy Scripture, talking nonsense on these topics; and we should take all means to prevent such an embarrassing situation, in which people show up vast ignorance in a Christian and laugh it to scorn. The shame is not so much that an ignorant individual is derided, but that people outside the household of the faith think our sacred writers held such opinions, and, to the great loss of those for whose salvation we toil, the writers of our Scripture are criticized and rejected as unlearned men.<br /><br />

 If they find a Christian mistaken in a field which they themselves know well and hear him maintaining his foolish opinions about our books, how are they going to believe those books in matters concerning the resurrection of the dead, the hope of eternal life, and the kingdom of heaven, when they think their pages are full of falsehoods on facts which they themselves have learnt from experience and the light of reason? <br /><br />

Reckless and incompetent expounders of holy Scripture bring untold trouble and sorrow on their wiser brethren when they are caught in one of their mischievous false opinions and are taken to task by those who are not bound by the authority of our sacred books. For then, to defend their utterly foolish and obviously untrue statements, they will try to call upon Holy Scripture for proof and even recite from memory many passages which they think support their position, although they understand neither what they say nor the things about which they make assertion.<sup>5</sup></blockquote>

<p>I am tempted here to let Augustine have the final word, but I think there are three final points worth highlighting here as a way of connecting this quote to the two books theory and thereby concluding our discussion of Augustine:</p>

<ol><li>The Book of Nature is clearly revelatory of God’s providential work in Christ, and even nonbelievers are capable of comprehending its complex order through the proper use of reason and experience (i.e. science properly understood).</li>
<li>The Book of Scripture is clearly revelatory of God’s providential work in Christ, and therefore is true and authoritative in <em>all</em> matters. The problem is that we often misinterpret Scripture by imposing our own preconceptions upon it rather than allowing it to speak for itself.</li>
<li>God’s two books can and should be read together in harmony when we are open to allowing them to speak for themselves on their own terms. Ultimately, they cannot contradict each other because the source of both is the same God and if they seem to be in contradiction it is because we have misread one or both of them, and we need to be willing therefore to allow ourselves to be open to thinking about either one in different ways, trusting that God will ultimately lead us to see the truth of the whole.</li></ol>

<h3>Notes</h3>
<p class="date">4.  In truth, these two kinds of providence are one and the same for Augustine because God in some ‘stands’ outside of time as its eternal creator. So, for Augustine, eternality is not everlasting time, but the complete lack of temporality altogether. In this sense, all of creation at all times is eternally present to God, and there is ultimately no difference between God’s governance over creation at its beginning from God’s governance at any other moment in its history. In a way, God governs all of history all at once.<br />

        <description>In this series, Ted Davis identifies the history, core tenets and assumptions about the Intelligent Design view.</description>
        <content:encoded><![CDATA[<h3>What’s in a name?</h3>
<p>According to <a href="http://www.merriam-webster.com/">Merriam Webster</a>, the term “intelligent design” has been used since at least 1847, in reference to “the theory that matter, the various forms of life, and the world were created by a designing intelligence.”  That’s a decent definition, also consistent with those offered by today’s proponents of intelligent design (ID). For example, the leading ID think tank, The Discovery Institute (Seattle), has <a href="http://www.intelligentdesign.org/whatisid.php">this</a>:</p>

<p style="margin: 0 0 0 10px;"><em>Intelligent design refers to a scientific research program as well as a community of scientists, philosophers and other scholars who seek evidence of design in nature. The theory of intelligent design holds that certain features of the universe and of living things are best explained by an intelligent cause, not an undirected process such as natural selection.</em></p>

<p>And in the opening sentence of a book he edited with philosopher Michael Ruse, ID theorist William Dembski said, “Intelligent Design is the hypothesis that in order to explain life it is necessary to suppose the action of an unevolved intelligence.” (<em>Debating Design</em>, p. 3)</p>

<p>On the other hand, while a recent contest on a prominent intelligent design (ID) <a href="http://www.uncommondescent.com/intelligent-design/contest-who-invented-the-phrase-intelligent-design-judged/">website</a> uncovered several other early uses of the term, it is important to note that it does not always mean exactly the same thing in each reference. The term itself has an interesting history, and while ID authors obviously did not invent the term “intelligent design,” they have given it specific content in recent years.  Indeed, they have even <em>removed</em> content in some cases: a point I will return to later is that, though it seems the only viable candidate for such an “unevolved intelligence” is God, ID proponents sometimes seem to do cartwheels to avoid saying as much.  When a term has such a complicated past, there simply is no substitute for looking at specific references in their own contexts as we move to seeing how ID plays out today as one of the 5 ways of relating science and the Bible. </p>

<p>Interestingly, many Protestant “modernist” scientists and theologians from William Jennings Bryan’s day (see my <a href="http://biologos.org/blog/science-and-the-bible-theistic-evolution-part-5">previous column</a>) unhesitatingly endorsed the idea that a designing intelligence lay behind nature. At least one such person, Nobel prize-winning physicist Arthur Holly Compton, even used the very term “intelligent design” in an address he gave at a Unitarian church in 1940: “The chance of a world such as ours occurring without intelligent design becomes more and more remote as we learn of its wonders.” (Quoting his pamphlet from 1940, <em>The Idea of God as Affected by Modern Knowledge</em>, p. 13. For more about this aspect of Compton’s views, click <a href="http://www.asa3.org/ASA/PSCF/2009/PSCF9-09Davis2.pdf">here</a>.) However, Compton regarded design as a philosophical and theological inference from science, not an explanation <em>within</em> science to be invoked when other explanations fail. He also accepted the common ancestry of humans and other organisms. This is a significant difference from the ID movement today, which offers ID as a <em>scientific alternative</em> to Darwinian evolution and (at least in many cases) seeks to undermine public confidence in common ancestry (even though ID <em>per se</em> is not actually opposed to it). </p>

<p>If any ID proponents are sympathetic to the type of religious modernism that Compton and his friends embraced, I cannot tell you who they are. In a curious, ironic twist, ID is often used by conservative Christian apologists partly to defend a cluster of traditional theological and hermeneutical positions that none of the modernists would have defended. A further irony: the intellectual descendants of the modernists—those scientists and theologians who occupy the left wing of the modern “dialogue” of science and religion—exhibit a studied avoidance of the term “design,” disconnecting them on that score from the modernists of the 1920s. </p>

<p>Many other contemporary writers, including some evangelical TEs, are also reluctant to use the word “design,” precisely because in their view it has been co-opted by ID proponents and they do not want readers to misunderstand their position(s). They may agree with ID proponents that certain features of the universe reflect divine design, but because they do not see design as a <em>scientific</em> explanation they employ other language. (Likewise, the YECs have co-opted the word “creationism” to mean just one specific understanding of God’s creative activity, leading most advocates of other views either to provide their own definitions of the word or else to avoid using it altogether. Politics dogs this conversation at every turn.)</p>

<h3>Core Tenets or Assumptions of Intelligent Design</h3>
<p>With that bit of historical context for the term “Intelligent Design,” let’s now look at the first of the Core Tenets of this perspective in its current state, and as it is most often used by those associated with the Intelligent Design movement.</p>

<p><strong>(1) The Bible is <em>NOT</em> to be mentioned (at least for now); ditto for “God” and “theology” as far as possible.</strong></p>

<p>This is a deliberate strategy, adopted for political reasons to keep arguments at the level of philosophy and science. Here, “political” refers to the American political system, with its constitutional disestablishment of religion, not to partisan politics. Since the 1980s, federal courts have consistently ruled that “creationism” (which was specifically of the YEC variety in the relevant cases) is sectarian religion, not science, and therefore it cannot be taught in public school science classes. Anxious to avoid a similar fate, proponents of ID always want to ensure that they are not perceived as advocates of “creationism.” The less they mention God and the Bible, the reasoning goes, the less likely they are to fall afoul of those decisions.</p>

<p class="caption-center"><img src="http://biologos.org/uploads/static-content/first_amendment.jpg" alt="" height="331" width="424"  /><br />The First Amendment to the U.S. Constitution, pertaining to the freedom of religion and the freedom of the press. <br />Source: http://www.rochester.edu/college/psc/images/Courses/Spring2008/FirstAmendment.png</p>

<p><a href="http://en.wikipedia.org/wiki/Phillip_E._Johnson">Phillip Johnson</a>, the former law professor who effectively began the ID movement some twenty years ago, has put it bluntly: “To put things on a more rational basis, the first thing that has to be done is to get the Bible out of the discussion.” He quickly adds, “This is not to say that the biblical issues are unimportant; the point is rather that the time to address them will be after we have separated materialist prejudice from scientific fact.” (<a href="http://www.touchstonemag.com/archives/article.php?id=12-04-018-f">“The Wedge: Breaking the Modernist Monopoly on Science,”</a> <em>Touchstone: A Journal of Mere Christianity</em>, July/August 1999, p. 22.) </p>

<p>If God and the Bible are really to be left out for the time being, then why am I discussing ID in a series on “Science and the Bible”? It’s a fair question. I simply don’t see any way meaningfully to avoid talking about ID apart from the culture wars in which it is embedded (I’ll say more about this in a subsequent column), and the Bible is never far from the surface when the battle being fought involves origins. Conservative Christians sense that ID really <em>is</em> about God—Dembski’s “unevolved intelligence”. As Dembski himself <a href="http://www.leaderu.com/offices/dembski/docs/bd-the_ac.html">has said</a>, “no intelligent agent who is strictly physical could have presided over the origin of the universe or the origin of life”, and there aren’t a lot of candidates for that job. Many Christians also identify strongly with the ways in which ID seeks to confront the secular establishment, in an explicitly-stated effort to combat what Johnson calls “the modernist scientific and intellectual world, with its materialist assumptions.” (“The Wedge,” p. 23.) They see it as a way of getting traditional theistic perspectives and Christian values back into the academy, once “design” has become an acceptable academic talking point—and it isn’t very far from there to conversations about “science and the Bible.” If this were not so, then why would so much ID literature be published by Christian presses? Indeed, when I tell church audiences with a straight face that ID purports not to be about the Bible at all, I’m usually met with considerable skepticism.</p>

<p>When I’m back in about two weeks, we’ll look at further Core Tenets of ID—the ones that have even less to do with the Bible, explicitly, and more to do with the way we approach the  study of the natural world.</p>

        <title>Series: Surprised by Jack: C.S. Lewis on Mere Christianity, the Bible, and Evolutionary Science</title>

        <description>In this five&#45;part series, David Williams responds to the book The Magician’s Twin: C.S. Lewis on Science, Scientism, and Society by John West and the Discovery Institute, showing that C.S. Lewis was a very complicated thinker whose views are hard to line up exactly with any camp in the current debates over the compatibility of Christian faith and evolutionary science.</description>
        <content:encoded><![CDATA[<p>“All reality is iconoclastic.”<sup>1</sup> When C.S. Lewis—or ‘Jack’ as his friends called him—penned that line in 1961, he was writing about God’s proclivity for repeatedly smashing our inevitably half-baked notions about Him.  But much the same can be said for what reality does to our own cultural icons as well. And, if nothing else, Lewis himself has become a cultural icon for many American evangelicals, identified by many as the 20th century’s Christian intellectual <em>par excellence</em>.</p>

<p>With his compelling personal story of becoming England’s “most reluctant convert,” his towering intellect, and his inimitable eloquence, American evangelicals’ lionization of Lewis is certainly understandable.<sup>2</sup> But when we attempt to lionize people we often ironically end up taming them, paring their claws so that our heroes and our preconceptions can safely cohabitate in our imaginations.  But Lewis is no safer a lion than Aslan, and he will not go quietly into our tidy evangelical boxes.  To be frank, American Evangelicalism’s infatuation with Lewis is in many respects somewhat odd.  For here is a pathologically populist movement with a penchant for Big Tent Revivalism, an obsession with liturgical innovation, a deep-seated suspicion of ecclesiastical tradition, and a raw nerve about the doctrine of justification, falling head-over-heels for a tweed-jacketed, Anglo-Catholic Oxford don—a curmudgeonly liturgical traditionalist who was fuzzy on the atonement, a believer in purgatory, and, as we shall see, whose views on Scripture, Genesis, and evolution position him well outside of American Evangelicalism’s standard theological paradigms.  All of that is to say that Lewis was not “just like us”—<em>any</em> of us—and if we would do him justice, we must be prepared to be <em>surprised</em> by Jack.</p>

<p>In what follows, I would like to look at three areas relevant to faith and science discussions where Lewis’s stated views might be surprising for his American Evangelical admirers—namely, his views on Scripture generally and Genesis in particular, his views on Adam and the doctrine of the Fall, and his views on evolutionary science and the myth of ‘Evolutionism.’</p>

<h3>Reflections on the Scriptures: Lewis on the Bible, Myth, & Fact </h3>

<p>Lewis derived his theological understanding of the Bible from his reading of Scripture, his intimate knowledge of the Church Fathers and the Medieval Doctors, and also from his awareness of modern biblical scholarship.  While Lewis was regularly critical of Modernist biblical scholarship’s naturalistic dismissal of the miraculous, its pedantry, literary tin-ear, and over-eagerness to conflate Jesus’ story with the stories of pagan mythologies (he had precious little patience for Rudolf Bultmann, for instance ), he was not at all given to the knee-jerk reactionary Fundamentalism which has held so much sway in American Evangelical culture.  In fact, Lewis incorporated many of the more well-supported conclusions of modern biblical criticism into his theology of Scripture, not least critical opinions about the historicity of much of the Old Testament.  In good Anglican fashion, Lewis creatively drew upon the deep resources of the Church’s grand Tradition in order to think through the contemporary problems posed by modern critical scholarship.  Here I wish to focus on three features of Lewis’s theological conception of Scripture—his understanding of the Bible as being <strong>incarnational</strong> and <strong>sacramental</strong> in character, and <strong>Christotelic</strong> in focus—before turning to his theological reading of Genesis 1-3.<sup>4</sup></p>

<h3>Inspiration and Incarnation</h3>

<p>According to Lewis, the Bible is both a vessel of the divine Word and also a profoundly human collection of documents. In his longest, most substantive piece on Scripture, chapter XI of <em>Reflections on the Psalms</em>, Lewis frames a thoroughly incarnational understanding of the Bible:</p>

<blockquote>The human qualities of the raw materials show through.  Naïvety, error, contradiction, even (as in the cursing Psalms) wickedness are not removed.  The total result is not “the Word of God” in the sense that every passage, in itself, gives impeccable science or history.  It carries the Word of God; and we (under grace, with attention to tradition and to interpreters wiser than ourselves, and with the use of such intelligence and learning as we may have) receive that word from it not by using it as an encyclopedia or an encyclical but by steeping ourselves in its tone or temper and so learning its overall message.<sup>5</sup></blockquote>

<p>Lewis’s reference to “[the] human qualities” of the Bible’s “raw materials” is suggestive.  As Peter Enns puts it in his book <em>Inspiration & Incarnation: Evangelicals and the Problem of the Old Testament</em>, the Incarnation of the Son and the inspiration of Scripture are “analogous.”<sup>6</sup>  Lewis clearly agrees.  He goes on in the chapter to articulate a theology of Scripture precisely in incarnational terms:</p>

<blockquote>For we are taught that the Incarnation itself proceeded “not by the conversion of the godhead into flesh, but by taking of (the) manhood into God”; in it human life becomes the vehicle of Divine life.  If the Scriptures proceed not by conversion of God’s word into literature but by taking up of a literature to be the vehicle of God’s word, this is not anomalous.<sup>7</sup></blockquote>

<p>According to Lewis, the means whereby God gives us Scripture is not by faxing us transcripts of inner-Trinitarian dialogue direct from Heaven, but rather, on analogy with the Incarnation, by taking up very human literature and utilizing it to communicate His Divine life to us.  </p>

<p>“We might have expected, we may think we should have preferred, an unrefracted light giving us ultimate truth in systematic form—something we could have tabulated and memorised and relied on like the multiplication table.”<sup>8</sup>  But God has instead deigned to give us a very human book, just as He deigned to send us a fully human Savior.  Lewis makes this point most poignantly in his Introduction to J.B. Phillips’s <em>Letters to Young Churches</em> where he writes:</p>

<blockquote>The same divine humility which decreed that God should become a baby at a peasant-woman’s breast, and later an arrested field-preacher in the hands of the Roman police, decreed also that He should be preached in a vulgar, prosaic and unliterary language.  If you can stomach the one, you can stomach the other.  The Incarnation is in that sense an irreverent doctrine: Christianity, in that sense, an incurably irreverent religion.  When we expect that it should have come before the World in all the beauty that we now feel in the Authorised Version we are as wide of the mark as the Jews were in expecting that the Messiah would come as a great earthly King.<sup>9</sup></blockquote>

<p>For Lewis, God’s work in the inspiration of Scripture not only communicates but also <em>emulates</em> God’s humble, self-effacing work in the Incarnation.  If the heart of Christianity, “an incurably irreverent religion,” should be the Incarnation, “an irreverent doctrine,” then it ought to come as no surprise that that doctrine should be most fundamentally communicated via an irreverent book. </p>

<p>A corollary of Lewis’ incarnational and sacramental view of Scripture is that when it comes to studying the Scriptures we must be prepared to be surprised.  Lewis warns against “the Fundamentalist’s” procedure of attempting to frame our ideas of Scripture <em>a priori</em>, deducing parameters for what the Scriptures can and cannot be from our preconceptions about God.  Lewis thinks such an approach to be a nonstarter:</p>

<blockquote>[There] is one argument which we should beware of using…: God must have done what is best, this is best, therefore God has done this.  For we are mortals and do not know what is best for us, and it is dangerous to prescribe what God must have done–especially when we cannot, for the life of us, see that He has after all done it.<sup>10</sup></blockquote>

<p>Instead, says Lewis, we should take a humble, a posteriori approach, looking and seeing just what kind of book it is that God has actually given us before making grand doctrinal declarations.  “To a human mind,” Lewis recognizes, an incarnational Bible “seems, no doubt, an untidy and leaky vehicle.”<sup>11</sup>  But it appears that this is what God has given us, and we must trust that God knows what He is doing.  As Lewis says, “Since this is what God has done, this, we must conclude, was best.”<sup>12</sup></p>


<h3>Myth Became Fact</h3>
<p>For Lewis, the Word is also like the sacrament. Just as ordinary water, bread, and wine are taken up into and become conduits for and communicators of the Divine life that we so desperately need, so, also, all-too-ordinary human writings are taken up into and become conduits for and communicators of the Divine life and word.  In Lewis’s view, we must receive the Divine word by approaching Scripture in a sacramental manner.  We “receive that word,” as Lewis says, again, “not by using [Scripture] as an encyclopedia or an encyclical but by steeping ourselves in its tone or temper and so learning its overall message.”<sup>13</sup> For Lewis, at least when it comes to the Old Testament, receiving the Word means more than simply paying critical attention to the surface meaning of the text, the <em>sensus literalis</em>.  Instead, we must press beyond the surface to the <em>sensus plenior</em>, to the “second sense” of the Old Testament, namely, Christ Himself.  “It is Christ Himself, not the Bible, who is the true word of God,” Lewis once wrote in a private letter.  “The Bible, read in the right spirit and with the guidance of good teachers, will bring us to Him.”<sup>14</sup> While such Christological <em>sensus plenior</em> interpretation may have fallen out of favor with many Protestants (to say nothing of thoroughgoing Modernist historical-critics), Lewis believes that “[we] are committed to it in principle by Our Lord Himself.”<sup>15</sup> Citing Jesus’ words to His disciples on the road to Emmaus, Lewis argues that Christ “accepted—indeed He claimed to be—the second meaning of Scripture.”  Citing a litany of Dominical sayings and New Testament texts, Lewis is clear that Christ is mysteriously the true spiritual center, climax, coherence, sum, and substance of the Old Testament Scriptures.<sup>16</sup></p>

<p>Lewis stands in good company in thinking along these lines.  The “good teachers” from which Lewis learned this hermeneutic are undoubtedly Aquinas, Bernard of Clairveaux, Augustine, Origen, and Irenaeus, not to mention the Apostles and Christ Himself.  In short, Lewis is standing within the mainstream tradition of pre-Reformation theological interpretation.  But Lewis is not simply striking a traditionalist posture.  Like a scribe trained for the Kingdom, he is prepared to bring forth treasures new and old.  By positioning himself within the grand tradition of pre-modern theological interpretation, Lewis frees himself to follow his highly-attuned modern literary-critical instincts regarding the historicity of much of the Old Testament while simultaneously upholding both a robust belief in the historicity of the Incarnation and a vital theological hermeneutic.    He writes:</p>

<blockquote>The earliest stratum of the Old Testament contains many truths in a form which I take to be legendary, or even mythical—hanging in the clouds, but gradually the truth condenses, becomes more and more historical.  From things like Noah’s Ark or the sun standing still upon Ajalon, you come down to the court memoirs of King David.  Finally you reach the New Testament and history reigns supreme, and the Truth is incarnate.  And “incarnate” here is more than a metaphor.  It is not an accidental resemblance that what, from the point of view of being, is stated in the form “God became Man,” should involve, from the point of view of human knowledge, the statement “Myth became Fact.”<sup>17</sup></blockquote>

<p>He sets up the above paragraph by saying, “[The Christian story] is like watching something come gradually into focus; first it hangs in the clouds of myth and ritual, vast and vague, then it condenses, grows hard and in a sense small, as a historical event in first century Palestine.”<sup>18</sup> Apart from the Incarnation, then, much of the Old Testament would be but “myth,” “ritual,” and “legend.”  These elements of the Old Testament only become tangible historical “Fact,” for Lewis, in the person and work of Christ.</p><br></br>

<p class="intro">Next time, Williams looks at how this understanding of Scripture framed Lewis' reading of Genesis 1-3.</p>

        <content:encoded><![CDATA[<p style="margin: 0px 30px 0px 30px;"><em>Truly, I say to you, unless a grain of wheat falls into the earth and dies, it remains alone; but if it dies, it bears much fruit</em>. —John 12:24</p>

<h3>Introduction</h3>

<p>One of the reasons that some of us are hesitant to accept evolutionary creation is that it seems to make God responsible for the suffering and death of innumerable creatures over millions of years—before humans ever existed or sinned against their creator.  Since we believe in and worship a God who is loving, benevolent, and all-powerful, it sounds quite implausible that our God would have created a world like that; therefore, any scientific evidence for evolution <em>must</em> be incorrect.</p>

<p>Other people look at the scientific evidence for evolution and find a compelling case that it has taken place during our earth's history.  On this basis they may conclude that if evolution is true, then the belief in an all-powerful, perfectly good God must be false!</p>

<p>The trouble with both of these views is that they tend to invoke a completely abstract, philosophical god, not the living God of the Bible—the God who became a human being, experienced unimaginable suffering, and died in a grotesque and humiliating public display.  The death of Jesus completely defied the expectations (and common sense) of his followers, as well as the expectations of any “rational” understanding of the way the Creator of the universe should act in the world.  On the cross, in the person of Jesus, God took upon himself far more suffering than any creature has ever experienced.</p>

<p>If God himself is willing to die, particularly in such a gruesome way, then perhaps we should at least consider the possibility of God allowing the death of other creatures, too.  But would this really be compatible with what we know of God through Scripture?  In this essay, we will explore this quandary through a “theology of the cross”, a concept articulated by pastor George Murphy in his book <em>Cosmos in the Light of the Cross</em>.<sup>1</sup> </p>

<h3>Theology of the cross</h3>

<p>Before we jump into the theological problems associated with evolution, let’s take a look at how we understand Christian theology itself.  For the reformer Martin Luther, any theology (or science) that tries to reach knowledge of God apart from the cross is bad theology.<sup>2</sup>  Instead, Luther pointed to a <em>theologia crucis</em>, in which the true God is seen first and foremost “through suffering and the cross”. To make his point even clearer, Luther insisted that “the CROSS alone is our theology”.<sup>3</sup>   It is the lens through which we view <em>everything</em>.</p>

<p>Of course Martin Luther, having lived in the 16th century, was not aware of the vast history of life on our planet (or any other aspect of modern science, for that matter), but George Murphy draws from Luther’s teachings the foundation that all human knowledge begins with the Word made flesh and crucified.<sup>4</sup>   With the cross of Christ as the ultimate framework through which we view reality, we are bound to view the processes of nature quite differently.  As Murphy explains it,</p>

<blockquote>A theology of the cross is an explication of belief in a God who becomes a participant in the history of the universe and thereby shares in the suffering, loss, and death that are part of worldly experience.<sup>5</sup></blockquote>

<p>God does not sit idly by and watch unaffected as his creatures suffer, but neither does he swoop in and make everything completely effortless and easy.  Instead he chose another way, the crucifixion of Jesus—certainly not the approach that we would have preferred! The apostle Peter went so far as to try to talk Jesus out of it, but he was met with a stern rebuke (Matthew 16:21-23).</p>

As humans, we are inclined to recoil in horror at the idea of God being closely associated with the death.  Yet in the crucifixion we are forced to think of death and God together.  Jesus himself did not draw back from immense pain and suffering, but instead works <em>in</em> it and <em>through</em> it to accomplish his plans. In the cross we learn who God is, the One who brings new life from death (and ultimately conquers death completely).<sup>6</sup> 

<h3>Why is evolution so disconcerting to Christians?</h3>

<p>The problem of suffering throughout all of human history is troubling enough for us to reconcile with a loving, personal God.  But in addition to that, the discovery of vast numbers of fossils reveals that death has taken place on a far greater scale than we had ever imagined.  Both the wide variety of extinct creatures and their sheer numbers is quite staggering, and it raises questions about our Creator:</p>

<blockquote>The picture of a God who is immune from suffering and death but who forces organisms through millions of generations and extinction is disturbing to those who believe in a God of love.<sup>7</sup></blockquote>

<p>The mass extinction of life on earth was already well established by the early 19th century—decades before Darwin’s research—and extinction can be empirically verified independent of any theory of evolution.<sup>8</sup>   The fact that the earth’s crust is a veritable graveyard of long-lost creatures is deeply troubling, and as late as the 1790’s, distinguished intellectuals such as Thomas Jefferson denied the very possibility of extinction.<sup>9</sup></p>

<p>But in addition to the reality of species extinction, the theory of evolution by natural selection proposes that new species also arise in an environment containing widespread pain and death.  Both the creatures that are now living and those that are gone are tainted by an “acrid smell of death”.<sup>10</sup>  It makes us wonder, if our Creator is not the God of the dead, but of the living (Mk. 12:27), where is God’s presence in the evolutionary picture?</p>

<p>In all honesty, creation through evolution is not what we would <em>expect</em> from God, but Scripture is full of examples in which God acts in unexpected ways.  After all, God’s choosing to undergo an agonizing death on a cross is not what we would expect from the all-powerful Creator of the universe, either.  In both cases, new life comes about through pain, suffering, and death.  As George Murphy puts it,
</p>

<blockquote>A priori ideas about God have to be overcome, and God's character has to be learned from God's self-revelation.<sup>11</sup></blockquote>

<p>God’s fullest self-expression is in Jesus Christ himself, one who is intimately familiar with and personally endured creaturely pain and death.  The theology of the cross reveals that God's self-revelation takes place in situations of suffering, loss, and apparent hopelessness, much like situations that occur through natural selection.<sup>12</sup></p>

<h3>The crucifixion is disconcerting too</h3>

<p>Not only is creation through evolution an unexpected and unsettling process, but so is the crucifixion of Jesus!  Killing someone by hanging them on a cross is an unbearably painful, prolonged, humiliating form of death. It was such a horrific type of public execution that it wasn't until after the Roman Empire stopped the practice of crucifixion—and people no longer witnessed it personally—did the cross become a visual object of devotion.<sup>13</sup> Our culture is sufficiently removed from crucifixion that we are desensitized to its original significance, but to connect it to our current context, imagine the reaction you would get by wearing jewelry designed to look like an electric chair.<sup>14</sup></p>

<p>Once we are more attuned to the brutality of crucifixion, it seems all the more striking that the cross is the sign of God’s work, what George Murphy calls “the trademark of God”.<sup>15</sup>   The suffering and death of Jesus is featured prominently in the Gospels, but the crucifixion-resurrection pattern is strongly resonant within the Old Testament, too.  Israel suffered and toiled as slaves in Egypt for centuries before they were rescued in the Exodus, bringing life to a people who were spiritually dead.  Centuries later, the nation of Israel would experience death again when the Babylonians destroyed the Davidic monarchy, burned their Temple, killed their people, and sent many into exile.<sup>16</sup>  Neither Israel (God’s chosen people) nor Jesus (God’s own son) were spared from death and suffering; rather, suffering seems to have been the way in which God re-forms and renews humanity to fully bear His own image.</p>

<h3>Redemption extends to all of creation</h3>

<p>Fortunately, God’s story does not end with death.  God gives new life after his creatures have been subjected to terrible circumstances.  Redemption was promised to Israel itself—Ezekiel’s vision of the valley of dry bones describes how God would renew His chosen people (Ezek 37:1-14).  Later, the astonishing resurrection of Jesus made salvation possible not only for Jews, but for all people in Christ (Gal 3:26-29).  Ultimately, the New Testament makes it clear that God’s renewal will encompass the entire Creation:</p>

<blockquote>For God was pleased to have all his fullness dwell in him, and through him <strong>to reconcile to himself all things, whether things on earth or things in heaven</strong>, by making peace through his blood, shed on the cross. (Colossians 1:19-20)</blockquote>  

<blockquote>With all wisdom and understanding, he made known to us the mystery of his will according to his good pleasure, which he purposed in Christ, to be put into effect when the times reach their fulfillment—<strong>to bring unity to all things in heaven and on earth</strong> under Christ. (Ephesians 1:8-10)</blockquote>

<p>Christians are accustomed to thinking of the death of Christ in regard to humans, but our culture rarely acknowledges God plan for the redemption of His entire creation.  This is partly attributable to the fact that discussions of creation and origins are often separated from the topic of salvation.<sup>17</sup>   In doing so we tend to marginalize Jesus as we argue about Genesis.  Rather than fall into this trap, if we view nature through a theology of the cross, we will see Christ as both the alpha and the omega point in discussions of life’s history and life’s future.  With this perspective, we are more apt to sense our solidarity with the rest of creation as we wait in eager anticipation of a glorious future:</p>
	
<blockquote>The creation waits in eager expectation for the children of God to be revealed. For the creation was subjected to frustration, not by its own choice, but by the will of the one who subjected it, in hope that the <strong>creation itself will be liberated from its bondage to decay and brought into the freedom and glory of the children of God</strong>. (Romans 8:19-21)</blockquote>

<h3>Conclusion</h3>

<p>As part of the Church’s conversation about the problem of natural evil, this essay is meant to be a brief introduction to a “theology of the cross”.  One can explore this concept in greater detail in Murphy’s book <em>The Cosmos in the Light of the Cross</em>.  While there is a lot more to be said, let me conclude with the following observation:  though evolution may not be compatible with <em>some</em> interpretations of Christianity, <strong>evolutionary creation is certainly compatible with the crucified Christ and the theology of the cross</strong>.  In the person of Jesus, God suffers with the world and ultimately redeems it.  As George Murphy puts in, “The world's pains are God's stigmata.”<sup>18</sup></p>

        <guid>http://biologos.org/blog/series/behe&#45;lenski&#45;and&#45;the&#45;edge&#45;of&#45;evolution?utm_source=RSS_Feed&amp;utm_medium=RSS&amp;utm_campaign=RSS_Syndication</guid>
        <description>In this series, we reexamine the claim made by Intelligent Design proponent Michael Behe to have found a limit to “Darwinian” evolution in light of recent results from the laboratory of Richard Lenski.</description>
        <content:encoded><![CDATA[<p>In previous posts in this <a href="http://biologos.org/blog/series/behe-lenski-and-the-edge-of-evolution">series</a>, we evaluated Behe’s claimed “edge” for what evolution can (and allegedly cannot) accomplish by examining the step-by-step path that bacteria in the Long Term Evolution Experiment (LTEE) took to arrive at a mechanism for utilizing citrate under aerobic conditions. In this post, we look at the implications of these results for another of Behe’s related ideas: that of irreducible complexity.</p>
 
<h3>Behe and IC</h3>

<p>Since we have previously explored Behe’s idea of irreducible complexity in an entire <a href="http://biologos.org/blog/series/understanding-evolution-the-evolutionary-origins-of-irreducible-complexity">series</a>, we will not revisit it here in great detail. It is important, however, to reemphasize how Behe defines irreducible complexity (IC). As we noted in the first part of that series, Behe frames his ideas on IC as a counter to Darwin’s ideas of gradualism.</p>

<p>For Behe, the argument for IC is a critique of gradual evolutionary processes, of the kind that Darwin saw as necessary for his theory to hold. When Behe introduces and defines IC in his book <em>Darwin’s Black Box</em>, he has a key quote from Darwin on gradualism explicitly in view:</p>

<blockquote>Darwin knew that his theory of gradual evolution by natural selection carried a heavy burden: "If it could be demonstrated that any complex organ existed which could not possibly have been formed by numerous, successive, slight modifications, my theory would absolutely break down."<br></br>

It is safe to say the most of the scientific skepticism about Darwinism in the past century has centered on this requirement… critics of Darwin have suspected that his criterion of failure had been met. But how can we be confident? What type of biological system could not be formed by “numerous, successive, slight modifications”? <br></br>

Well, for starters, a system that is irreducibly complex. By irreducibly complex I mean a single system composed of several well-matched, interacting parts that contribute to the basic function, wherein the removal of any one of the parts causes the system to effectively cease functioning. An irreducibly complex system cannot be produced directly (that is, by continuously improving the initial function, which continues to work by the same mechanism) by slight, successive modifications of a precursor system, because any precursor to an irreducibly complex system that is missing a part is by definition nonfunctional. An irreducibly complex biological system, if there is such a thing, would be a powerful challenge to Darwinian evolution.<br></br>(<em>Darwin’s Black Box</em>, p. 39) </blockquote>

<p>The definition of an IC system is thus straightforward: it is a matched group of components, where all the components are necessary for the function of the system. The necessity of each component can be demonstrated by attempting to remove it – if the system no longer works if even one component is removed, it is by definition IC.</p>


<h3>Behe and exaptation</h3> 
 
<p>The standard response to Behe’s argument from IC is to discuss the evolutionary concept of exaptation: that new systems and functions are cobbled together from components that have functional roles in other systems already present in the cell. Behe discusses, and ultimately dismisses this idea in <em>Darwin’s Black Box</em> as follows: </p>

<blockquote>In Chapter 2 I noted that one couldn’t take specialized parts of other complex systems (such as the spring from a grandfather clock) and use them directly as specialized parts of a second irreducible system (like a mousetrap) unless the parts were first extensively modified. Analogous parts playing roles in other systems cannot relieve the irreducible complexity of a new system; the focus simply shifts from “making” the components to “modifying” them. In either case, there is no new function unless an intelligent agent guides the setup.
</blockquote>

<p>So for Behe, two points are clear: parts selected for function in one system cannot be exapted for use in other systems since they would require too many modifications; and the emergence of a new function is the indication that an intelligent agent is guiding the process. </p>

<p>Behe has <a href="http://www.evolutionnews.org/2012/11/rose-colored_gl066361.html">responded</a> to my previous posts to claim that the tandem duplication event that brought about the Cit+ actualization event should not be considered a gain-of-FCT mutation under his criteria:</p> 

<blockquote>The gene duplication which brought an oxygen-tolerant promoter near to the citT gene did not make any new functional element. Rather, it simply duplicated existing features. The two FCTs comprising the oxygen tolerant citrate transporter locus -- the promoter and the gene -- were functional before the duplication and functional after. I had written in my review that one type of mutation that could be categorized as a gain-of-FCT was gene duplication with subsequent sequence modification, to allow the gene to specialize in some task. Venema thinks the mutation observed by Lenski is such an event. He has overlooked the fact that there was no subsequent sequence modification; a segment of DNA simply tandemly duplicated, bringing together two pre-existing FCTs.</blockquote>

<p>As an aside, quibbling over whether this mutation constitutes a “genuine gain-of-FCT” mutation is not my purpose here, since the definition is Behe’s to define, and I am not aware of anyone else in the scientific literature who uses Behe’s definitions.  That said, I consider it passing strange to claim that a series of events that produced a gene that has a new sequence and functional properties distinct from either of its component parts does not constitute the production of a new “functional coded element.” If nothing else, it is a functional coded element that has not previously existed, cobbled together from parts of other functional coded elements, displaying new, adaptive properties. If according to Behe’s definition that’s not “new” or a “gain” then I guess it’s not, but that seems to me to torture the words “new” and “gain” beyond recognition. But I digress.</p>

<p>The important point for our purposes, however, lies elsewhere. Note carefully how Behe describes the Cit+ actualization event. By dividing the new aerobic citrate transporter gene into two previously existing FCTs, Behe is describing an exaptation event. The one FCT (the aerobic promoter) starts off as a necessary component of a gene transcribed when oxygen is present. As such it is under selection for that function, which has nothing to do with expressing a citrate transporter. The second FCT (the citrate transporter amino acid coding sequence) is under selection to be a citrate transporter, which has nothing to do with the function of the gene the promoter comes from. The Cit+ actualization event, then, exapts these two FCTs by placing them together to create a new function (which Behe does not mention). </p>

<p>And here’s the kicker: the new system (expression of the citrate transporter when oxygen is present) requires both FCTs in order to work. It has become a system of “well matched, interacting parts that contribute to the basic function” (i.e. transporting citrate in the presence of oxygen) “wherein the removal of any one of the parts causes the system to effectively cease functioning.” </p>

<p>In other words, it is a new IC system – a small and relatively simple system, yes, but nonetheless IC. Now, I’m fairly sure that Behe would not define this system as IC, since the documentation of an IC system evolving would seriously undermine his thesis. I am interested, however, in how he will handle this development, on two fronts. First, he would need to explain specifically why two exapted FCTs that are required together for a basic function does not constitute an IC system (if indeed he wishes to preserve his definition). Secondly, given that he allows for exaptation in this case, he needs to explain how exaptation is not a threat to IC in general. In <em>Darwin’s Black Box</em> he disallows exaptation altogether, but that option is no longer on the table. </p>

<p>In the next post in this series, we’ll continue to explore the evidence for exaptation  as a means to build new FCTs, and go on to examine the implications of this evidence for Douglas Axe’s proposed limit to evolutionary mechanisms.</p>

        <title>Medieval Christianity and the Rise of Modern Science, Part 1</title>

        <description>There has been no great conflict between science and religion: on the contrary, Christianity was an essential factor in the rise of modern science.</description>
        <content:encoded><![CDATA[<p>Readers of the Biologus Forum do not need to be told that the alleged conflict between science and religion is a myth. The conflict thesis was born in the salons of <em>ancien régime</em> France where <em>philosophes</em> like Voltaire and Jean le Rond d’Alembert used it as a weapon against the Catholic Church. It was further developed in Victorian England by T.H. Huxley in his battle to diminish the influence of the clergy in London’s Royal Society. And it was perfected in American universities by the likes of Andrew Dickson White, first president of Cornell University, who provided the theory with intellectual ballast in his heavily annotated <em>A History of the Warfare of Science with Theology</em> (1896). Today, historians of science have long disposed of the conflict thesis, but it lives on in the popular imagination.</p>

<p>The inevitable companion to the idea that the Church has held back scientific progress is that we must look outside Christendom to discover the origin of modern science. But this is also false. Modern science stands as one of the great achievements of Western civilization. And, despite what we have often heard, it is certainly an achievement of the West, not of Islam, China or even ancient Greece. Many historians of science are still reluctant to admit this. This may be because the fad of post-modernism bit them hard and has refused to let go. They have developed a habit of praising Arabic and ancient Greek science as successful on their own terms but they have lost sight of the fact that, viewed objectively, the theories advanced by early science were quite false.</p>

<p>Of course, we should have respect the Greek and Islamic natural philosophers who struggled to comprehend the world. But most of what they taught, through no fault of their own, was woefully inaccurate. This was because their aims for science were nothing like ours.  They wanted to understand nature in terms that made sense of their ethical or religious beliefs, and formed their theories accordingly.</p> 

<p class="caption-left"><img src="http://biologos.org/uploads/static-content/galen_lithograph.jpg" alt="" height="301" width="250"  /></p>

<p>To take just one example, pre-modern medicine was an unmitigated disaster, far more likely to kill patients than cure them. Treatments such as bleeding and purging could only weaken the constitution of the sick, reducing their bodies’ capacity to fight off infection.   It is no surprise to find that the most celebrated doctor of antiquity, Galen of Pergamum (left), considered himself as much a philosopher as a healer.  Given the ineffectiveness of learned physicians, it’s little wonder that people put so much stock in miracles and magic. Perhaps the most surprising thing is that doctors were able to maintain their professional status through all the centuries that they could do little more that hasten their clients to the grave. Luckily for us, we can be much more confident that modern medicine really can cure us of many diseases. So the history of science should be the story of how we went from being fundamentally wrong about the natural world to being, in large part, right.</p>

<p>Science as we imagine it today, with laboratories, experiments and a professional culture, is a recent phenomenon that did not appear until the nineteenth century. But its origins can be found much earlier and we usually look for them in the period known as the ‘scientific revolution’. It is commonly believed that the recovery of Greek philosophy during the Renaissance gave Western civilization the inspiration it needed to launch this revolutionary way of looking at the world. In this view, hardly anything of consequence for science occurred between the fall of Rome and the era of Copernicus and Galileo. Carl Sagan produced a timeline of scientific progress in his book Cosmos (1980) showing nothing at all happening between AD415 and AD1543. But this is an illusion foisted on us by the same <em>mentalité</em> that declared science and religion must be in conflict. The truth is that to understand why modern science arose uniquely in the West, we have to travel all the way back to the Middle Ages.</p>

<h3>Dispelling Myths</h3>

<p>Before we do that, we should finally dispose of the two myths about scientific progress that we noted above. Firstly, as we have seen, the popular view remains that religion has held back science at every opportunity. Many people still believe that science has advanced by fighting superstition and making the world safe for rational enquiry. It is true that certain religious doctrines contradict some scientific discoveries. The creation/evolution controversy is a case in point, but such quarrels have been surprisingly rare. Even the infamous trial of Galileo, the other example of conflict most often cited, was an aberration in the Catholic Church’s usual supportive attitude towards science. </p>

<p>On the other hand, the problems with the thesis that science and faith are locked in a historical conflict are formidable. For a start, the so-called ‘scientific revolution’ in the seventeenth century coincided with the period when Christian belief in Europe was at its strongest. Only after science had triumphed did religion start to suffer any sort of decline. And, if Christianity really had tried to hold back scientific progress, the chances are that it would have succeeded. Modern science would not have arisen in Christian Europe at all.</p>

<p class="caption-right"><img src="http://biologos.org/uploads/static-content/calixtus_III.jpg" alt="" height="425" width="275"  /></p>

<p>As it happens, much of the evidence marshaled in favor of the conflict thesis turns out to be bogus. The Church never tried to outlaw zero or human dissection; no one was burnt at the stake for scientific ideas (not even Giordano Bruno); and no educated person in the Middle Ages thought that the world was flat, whatever the Bible might imply. Popes have had better things to do than banning vaccination or lightning conductors on churches. The thought of a pope excommunicating Halley’s Comet is absurd, but this has not prevented the tale of Calixtus III (right) doing just that from entering scientific folklore. It is remarkable that authors today, who consider themselves skeptics, can swallow some of these stories whole. Carl Sagan introduced his readers to a ‘baloney detector’ in his book, <em>The Demon-Haunted World</em> (1997). It is a great shame he never used it on his own writings. He presented a completely fictitious account of the murder of the pagan philosopher Hypatia in <em>Cosmos</em> and falsely blamed Christians for the destruction of the Alexandrian library.</p>

<p>Zealous Victorian historians did find occasional examples of ecclesiastical stupidity, such as the Boston pastor who warned that lightning strikes caused earthquakes. They rewrote history to make these marginal figures into leaders of opinion. Religious dissidents who paid the ultimate price for their faith were recast as champions of reason. Pope Boniface VIII issued a bull intended to stop crusaders sending their bones home for burial; he would have been most surprised to hear that, according to Andrew Dickson White, he had legislated against human dissection. Whenever a priest questioned a scientific theory, which they often did in their capacity as amateur scientists, this was held up as an example of religious obstruction. Historians have been debunking these legends for over a century now, but they continue to be recycled by each new generation.</p>

<h3>The role of ancient Greek and Islamic thought</h3>

<p>The other myth about the rise of science is that westerners only had to pick up the baton from the ancient Greeks, or, as has been more recently alleged, the Islamic caliphate. In reality, modern science is qualitatively different from the natural philosophy practiced by the likes of Aristotle or Avicenna. Aristotle started from the passive observation of nature and then built up a system based on rational argument. This had two enormous disadvantages: compared to controlled experiments, passive observation is usually misleading; and not even Aristotle’s powers of reason could prevent blunders in his arguments.</p>

<p>His discussion of motion is a case in point. He observed that everyday objects tend to stop when nothing was pushing them. From this observation, he deduced the principle that all moving objects must be moved by something else. He elevated this principle to the status of a logical certainty and then used it to explain other kinds of motion. He even thought that it successfully proved the existence of God. If the universe as a whole is full of movement, he argued, it requires an exterior unmoved mover,—that is, God—to keep it going. But of course, Aristotle’s initial observation was just a specific instance without any general applicability. We now know that objects do not stop when there is no force on them. They tend to keep going in a straight line: a principle enshrined as Newton’s First Law. Other observations led Aristotle to decree it certain that a vacuum can never exist; that heavy objects fall faster than light ones and that the earth must occupy the centre of the universe. All wrong. Aristotle, alas, was mistaken about almost everything. This was not because he was a fool but because he was practicing a natural philosophy that could never lead to true theories.</p>

<p class="caption-right"><img src="http://biologos.org/uploads/static-content/alhazen.png" alt="" height="303" width="250"  /><br />Alhazen</p>

<p>Islamic science suffered from similar drawbacks. Advances made by Muslim natural philosophers were significant, but rather more modest than we are usually led to believe. The importance of Alhazen’s investigations into the properties of light is indubitable. They were used by Roger Bacon in his own writings on <em>perspectiva</em> and thence were integrated into the modern theory of vision developed by Johannes Kepler. Even so, Alhazen’s experimental method was limited and not carried forward by his immediate successors. Similarly, the intuition of Ibn al-Nafis, in the thirteenth century, concerning the circulation of blood between the heart and the lungs is deeply impressive. But there is no evidence that he had any impact on the rediscovery of this phenomenon by Michael Servetus and Realdo Columbo three centuries later.</p>

<p>Consequently, we should be skeptical about some of the claims made for Islamic science in some recent television shows and books, not to mention in Wikipedia. That said, the misattribution of scientific advances to Islamic sources has sometimes been the fault of the pioneers who actually discovered them. Alchemy is a case in point. During the Middle Ages, it was customary for Christian alchemists to write their treatises under the name of the fabled Arab savant Geber. It is not surprising that later historians mistakenly assigned developments such as the first production of powerful acids as well as the isolation of alcohol to Geber himself. Alcohol was even assigned an Arabic name by Christian authors. We now know that he probably did not write any of the works attributed to him.</p>

<p>On the other hand, there was one towering exception to the rule that early science tended to be bunk: both the Greeks and Arabs excelled in mathematics. This was because pure rationalism works a treat when it is restricted to geometry and arithmetic. The imams had plenty of practical uses for math, as well: the Muslim calendar follows the moon and not the solar year, while mosques had to be orientated towards Mecca. Both these religious problems required mathematical solutions. It’s also said that the complicated rules of Islamic inheritance made algebra indispensable. Even our word algebra is a corruption of <em>al-jabr</em>, the name of an Arabic textbook widely used by Christians.</p>  

<p>Despite these genuine contributions, it is nevertheless fair to say that neither Aristotelian rationality nor Islamic mathematics was the key to the developments that made the modern world possible. As we shall see in the second part of this essay tomorrow, the very different cultural situation in medieval Europe allowed for Aristotle’s faulty method to be criticised by the Catholic Church, meaning that previously forbidden ideas could flourish.  The Church also made natural philosophy a compulsory part of the course that it required trainee theologians to follow. So, unlike in Islamic <em>madrassas</em>, science had a central place in Christian centers of learning. Indeed, it was a Christian worldview that proved especially compatible with—even necessary for—the rise of modern science.</p>

        <title>Science and the Bible: Theistic Evolution, Part 2</title>

        <guid>http://biologos.org/blog/science&#45;and&#45;the&#45;bible&#45;theistic&#45;evolution&#45;part&#45;ii?utm_source=RSS_Feed&amp;utm_medium=RSS&amp;utm_campaign=RSS_Syndication</guid>
        <description>Everyone reading this column originated in the union of two cells, one from each parent. Everyone reading this is also created in the image of God. Each of these two sentences is true, but the truths they proclaim are of a different order. The first neither implies nor negates the second.</description>
        <content:encoded><![CDATA[<p>In the first part of this column, I presented five core tenets or assumptions of Theistic Evolution. The discussion resumes today with some implications and conclusions that follow from those assumptions, with further implications and conclusions coming in about two weeks.</p>

<h3>Some implications and conclusions of Theistic Evolution</h3>
<strong><p>(1) For TEs, both the verbal and the conceptual language of the Bible are “pre-scientific,” not just popular and phenomenological. In other words, God’s revelation is embedded in an ancient worldview that is simply assumed by the text, not challenged there. Thus, the Bible contains ancient science—science that would be factually erroneous if we took it at face value as part of what God intended to teach us.</p></strong>

<p>Bernard Ramm argued for just such a position in <a href="http://www.asa3.org/ASA/PSCF/1992/PSCF3-92Spradley.html"><em>The Christian View of Science and Scripture</em></a>, even though he was an OEC, not a TE. Denis Lamoureux takes it further in his recent book, <a href="http://www.ualberta.ca/~dlamoure/ilj_book.htm"><em>I Love Jesus & I Accept Evolution</em></a>. A glance at the <a href="http://www.ualberta.ca/~dlamoure/ilj_table_of_contents.pdf">table of contents</a> shows that he emphasizes the presence of “ancient science in the Bible” and teaches us how to interpret the Bible in light of this. Just as we don’t take biblical astronomy “literally,” with its 3-tiered universe, we shouldn’t take biblical biology “literally,” with its fixed species and separate creations a few thousand years ago.  </p>

<strong><p>(2) Even though TE advocates sometimes speak about God as the author of two “books” (nature and Scripture), TE is not usually seen as a Concordist position. At least among evangelical TEs, a position known as “Complementarity” is probably the most widely endorsed model for relating science and the Bible, though it is not the only one. </p></strong>

<p>For a concise description of Complementarity, I borrow the words of Stanford physicist (now retired) <a href="http://www.asa3.org/ASA/SEARCH/SEARCHBube9-90.pdf">Richard Bube</a>, who wrote three books about science and Christianity, taught a course about it for decades, and edited the <a href="http://network.asa3.org/?page=PSCF"><em>Journal of the American Scientific Affiliation</em></a> (now called <em>Perspectives on Science & Christian Faith</em>) for many years. In his book, <a href="http://www.amazon.com/Putting-All-Together-Richard-Bube/dp/0819197556"><em>Putting It All Together</em></a>, Bube presented seven “patterns” for relating science to faith (<a href="http://www.asa3.org/ASA/newsletter/Seven%20Patterns.htm">here</a> and <a href="http://www.christianmind.org/illus/patterns_color.htm">here</a>), ending with his personal favorite, Complementarity, described as follows:</p>

<blockquote><p>“Science and theology tell us different kinds of things about the same things. Each, when true to its own authentic capabilities, provides us with valid insights into the nature of reality from different perspectives. It is the task of individuals and communities of individuals to integrate these two types of insights to obtain an adequate and coherent view of reality.” (p. 166)</p></blockquote>

<p>I’ll offer my own example to illustrate this model. Everyone reading this column originated in the union of two cells, one from each parent. Everyone reading this is also created in the image of God. Each of these two sentences is true, but the truths they proclaim are of a different order. The first neither implies nor negates the second. You can see where this is going: for TEs, the truth (in their view) that we are descended from other primates neither implies nor negates the truth that we are created in the image of God.  </p>

<p>The Complementarity view, as I’ve briefly presented it, might seem quite shallow—nothing more than the simple, unsupported claim that science is about HOW and religion is about WHY. Readers who want a subtler account are invited to study Christopher Rios’ <a href="http://www.asa3.org/ASA/PSCF/2011/PSCF6-11Rios.pdf">article about its development</a>. Rios quite properly stresses the work of two important British scientists from the last century, quantum chemist <a href="http://en.wikipedia.org/wiki/Charles_Coulson">Charles A. Coulson </a>and his friend, brain theorist <a href="http://www.asa3.org/ASA/PSCF/1992/PSCF3-92Haas.html">Donald M. MacKay</a>, one of the most prolific and thoughtful Christian thinkers of his generation. If you don’t know MacKay, I unreservedly recommend that you get acquainted, but his work is so wide-ranging that I am hesitant to recommend a single starting place. Evolution was not one of his chief interests (I don’t offer him as a prime example of TE per se), but I can’t think of anyone who wrote more about the Complementarity model of science and Christian faith.</p>

<p class="caption-right"><img src="http://biologos.org/uploads/static-content/davis_te_pic_2.jpg" alt="" height="324" width="270"  /></p>

<p>Physicist-theologian <a href="http://www.starcourse.org/jcp/">John Polkinghorne</a> can also be understood as a proponent of Complementarity, though I would not characterize his position solely in those terms. His overall vision captures the essence of Complementarity: theology complements the limited picture of reality given to us by science; it goes beyond science, providing a larger metaphysical framework within which both nature and the science of nature are more intelligible (see below for more). Many of his books are conceptually deep, discouraging casual readers, but they are also eloquent and very creative, making the hard work of reading them time well spent. There simply is no good substitute for diving into them yourself. I’ve reviewed one of his recent books <a href="http://www.firstthings.com/onthesquare/2009/07/the-motivated-belief-of-john-polkinghorne">here</a>.</p>

<p>(INVITATION: If you would like to take part in a full discussion of one of his books here at BioLogos, at some point down the road, please let me know, either in a comment below or privately (tdavisATmessiahDOTedu). Don’t make the commitment lightly—you would be expected to purchase and read the book—but please take the invitation seriously and respond accordingly.) </p>

<strong><p>(3) Advocates of TE often emphasize theology of nature more than natural theology. They may still do natural theology, but they approach it more modestly—for them, theism cannot be “proved” from nature, but it still makes more sense of our whole experience of the world than atheism. </p></strong>
<p>A theology of nature starts from the assumption that God exists and then seeks to understand the whole of nature in light of this. Polkinghorne does this in many of his books (see the review linked above for some specific examples). Natural theology, on the other hand, is the effort to demonstrate God’s existence (including some of God’s attributes, such as power, wisdom, and goodness) from reason or nature, without appealing to the Bible. Many Christian authors since the patristic period have done this, often citing the first chapter of Romans, though some of the most important have had doubts about the value of the whole enterprise; two prominent examples would be Blaise Pascal (see the article by George Murphy <a href="http://www.christianhistorymagazine.org/wp-content/wS8wVsy62N/chm76-t3e6S.pdf">here</a>) and <a href="http://www.asa3.org/ASA/PSCF/2001/PSCF3-01Kalthoff.html">John Henry Newman</a>. </p>

<p>The golden age for natural theology lasted from the late 17th century (when Boyle and Newton were outspoken advocates of using science to argue for God’s existence) down through the mid-19th century, when Darwinian evolution provided a serious challenge to natural theological arguments based on “contrivances,” aspects of nature that appeared to be exquisitely crafted for a specific purpose by the Creator. Although it’s not true “That Darwin Destroyed Natural Theology,” (see the chapter by Jon Roberts <a href="http://www.hup.harvard.edu/catalog.php?isbn=9780674057418&content=toc">here</a>), it is true that TE authors no longer appeal to intricate biological “contrivances” to make their case. Prior to Darwin, a leading natural theologian, the great scholar <a href="http://plato.stanford.edu/entries/whewell/">William Whewell</a>, had already made the case for a different type of natural theology in his famous contribution to the Bridgewater Treatises, a series of <a href="http://www.victorianweb.org/science/bridgewater.html">eight books on natural theology</a> from the 1830s: “But with regard to the material world, we can at least go so far as this;—we can perceive that events are brought about, not by insulated interpositions of divine power, exerted in each particular case, but by the establishment of general laws” (<em>Astronomy and General Physics Considered with Reference to Natural Theology</em>, p. 356 in the fifth London edition of 1836). Ironically, Darwin placed this very passage directly opposite the title page in <em>On the Origin of Species</em> (1859). </p>

<p>Just a few years later, a Unitarian chemist from Harvard, <a href="http://www.hyle.org/journal/issues/17-1/contakes-kyle.pdf">Josiah Parsons Cooke, Jr.</a>, replied to Darwin in a book called <em>Religion and Chemistry; or, Proofs of God’s Plan in the Atmosphere and Its Elements</em> (1864). Cooke got around Darwin by inquiring into the basic properties of matter itself—the features of the physical universe that make biology possible at all. “There is abundant evidence of design in the properties of the chemical elements alone,” he argued, especially as they combine to make the unique substance we call water. Natural theology had found a more solid foundation, “which no theories of organic development can shake.”</p>

<p class="caption-center"><img src="http://biologos.org/uploads/static-content/davis_te_pic_3.jpg" alt="" height="427" width="570"  /></p>

<p>Contemporary TEs do pretty much the same thing. They look for evidence of “design” or “purpose” in the nature of nature itself, not in biological “contrivances.” Discussions of the <a href="http://www.unm.edu/~hdelaney/finetuning.gif">“fine tuning” of the universe</a> are common in TE literature, including Francis Collins’ book, <a href="http://biologos.org/resources/books/the-language-of-god"><em>The Language of God</em></a> and Ken Miller’s book, <a href="http://biologos.org/resources/books/finding-darwins-god"><em>Finding Darwin’s God</em></a>. Philosopher Robin Collins (who is writing a superb book about the fine tuning of the laws of nature) provides a helpful introduction to the terms and the issues <a href="http://www.infidels.org/library/modern/robin_collins/design.html">here</a>. Polkinghorne raises fundamental questions about the very intelligibility of nature in the wonderful title chapter in <a href="http://biologos.org/resources/books/belief-in-god-in-an-age-of-science"><em>Belief in God in an Age of Science</em></a>. Let’s pay careful attention to what he says about his overall approach:</p>

<blockquote><p>“This new natural theology differs from the old-style natural theology of Anselm and Aquinas by refraining from talking about ‘proofs’ of God’s existence and by being content with the more modest role of offering theistic belief as an insightful account of what is going on. It differs from the old-style natural theology of William Paley and others by basing its arguments not upon particular occurrences (the coming-to-be of the eye or of life itself), but on the character of the physical fabric of the world, which is the necessary ground for the possibility of any occurrence (it appeals to cosmic rationality and the anthropic form of the laws of nature) ... [Consequently] the new-style natural theology in no way seeks to be a rival to scientific explanation but rather it aims to complement that explanation by setting it within a wider and more profound context of understanding. Science rejoices in the rational accessibility of the physical world and uses the laws of nature to explain particular occurrences in cosmic and terrestrial history, but it is unable of itself to offer any reason why these laws take the particular (anthropically fruitful) form that they do, or why we can discover them through mathematical insight.” (pp. 10-11)</p></blockquote>

<h3>Looking Ahead</h3>
<p>Sorry to stop mid-stream, but this is enough for now. This discussion resumes in about two weeks with more implications and conclusions of TE. There should be enough here to keep us going until then! </p>]]></content:encoded>

        <description>The debate is often not about evidence, but about making sure that others do not transgress our interpretive boundaries and insist that we&apos;re wrong. We&apos;ve bitten from the tree of knowledge and we love its taste.</description>
        <content:encoded><![CDATA[<h3>What we know</h3>

<p>Genesis is one of my favorite books of the Bible. I read through it probably once every few months and repeatedly grind my Hebrew language skills on its opening chapters. Unlike Leviticus (at least in the opinion of <em>most</em> people I know), the Genesis narrative is exciting and adventurous. Some of our favorite stories come out of the book: Noah and the Ark, The Tower of Babel, Abraham and Isaac, Joseph and the Coat of Many Colors, and so on.</p>

<p>But no story is perhaps as infamous and well known as the creation account (or accounts) as presented in Genesis 1-2. Almost every Christian or Jew, even those less than devout, know the opening words to the tale: “In the beginning, God created the heavens and the earth.” We know that God created the earth in six days. We know Eve was taken from Adam's rib for a companion. We know that God called the general creation “good”, the special creation of man “very good” and, at the very end of it all, took a day of rest (which I'm sure most of us would call “very good.”)</p>

<p>Of course, we know all of this. Yet we challenge it (and are challenged by it), continually, when we consider the variety of interpretations of how this story intersects the world as described by science. With Genesis, are we dealing with a literal scientific account, where “day” means 24-hours; are we dealing with metaphorical “days” in which epochs or periods of time or even processes are being described; or are we readers of a creation mythology from the Ancient Near East that doesn’t have anything directly to do with material origins? Interpretations go on and on, as anyone who has spent any time at all studying the creation debate knows. By and large, however, we can probably categorize Genesis interpreters into three camps: the Young Earth Creationists, the Old Earth Creationists, and the Theistic Evolutionists.</p>

<p>Now, I have the unique benefit of falling into all of these individual camps at one point or another in my life, sometimes even mixing them up. I have made a strong transition from being a die-hard Young Earth Creationist to being convinced that the evolutionary story is, in fact, the more substantiated and evidenced position. I say this with no pride, since my own transition involved many agonizing questions, a whole lot of reading, and a significant internal spiritual battle: what I believed about when and how the earth was created would not only change the way I read Scripture, it would also change certain aspects of how I viewed the Creator. </p>

<p>While I've certainly learned a lot of information on my journey, it was not an accumulation of facts that has kept me following Christ through all the ups and downs, but Jesus himself, and the knowledge that truth is not something which the Christian should find spiritually threatening.  Nevertheless, those same ups and downs—and my internalization of each of these views on creation in turn—has provided me with one simple realization about the debate over scripture and evolution: most of us are not so committed to finding the truth about Genesis and creation as we are to sustaining and maintaining our own interpretive boundaries and the boundaries of the communities which influence us. In other words, the debate is often not so much over Genesis—or even over whether we can all follow the same God when we believe different things about how he created—it's over our own ability to be right. I know this because admitting that I was wrong was the most difficult part of my own transition.</p>

<h3>Interpretive communities</h3>

<p>While I am pretty convinced of the truth of an evolutionary portrait of reality and an ANE reading of Genesis similar to that espoused by scholars like Peter Enns or Bruce Waltke, I can still make this claim about interpretive communities because my intention is <em>not</em> to dissuade others from debating the issues involved, but to ask that we simply recognize our own limits and check them as often as possible.  This is part of following Jesus, is it not? Unfortunately, vigorous debate often deteriorates quickly into screaming matches where proponents of one position or another simply are talking heads, speaking past each other and forgetting our fellowship in Christ. We play into the same interpretive competition that the Pharisee and Sadducee scribes were well known for, each claiming to have a proper interpretation of the Scriptures, but all the while forgetting that interpretive arguments matter exceptionally little if a genuine search for God is not at the forefront.  This is certainly not to insist that the discussions cease, but rather, to insist that these discussions can only be propelled forward if individuals—of whatever stripe—step outside of their own interpretive boundaries and communities and humbly present themselves before God, seeking His truth alone. It is to insist that “system maintenance” must die along with the self, because only then can we allow Scripture to interpret itself. Unfortunately (and this is an issue that goes <em>way</em> beyond the Genesis text), too many of us are more committed to a specific model than we are committed to seeking God’s truth, whatever inconvenience to us that truth proves to be. </p>

<p>In 2006, for instance, I heard a popular and well-trained Young Earth paleontologist make the following statement: “If all the evidence turns against young earth creationism, I will still believe it because that's what the Bible says.” I followed up with him in a conversation a year later over lunch and quickly realized that I did not misunderstand his statement.  For him, the parameters of his convictions were set in concrete and the truth of the overarching story of Christianity rested on these parameters not being crossed. In his view, the Bible absolutely and fundamentally teaches a universe which came into existence 6,000-10,000 years ago; to deny that is to deny Scripture, and if evidence turned up to the contrary one <em>must</em> not alter those parameters but, instead, search (perhaps in vain) for counter-evidence or be willing to live in blind faith. For this paleontologist, confident Christianity hinged on the stability of those borders of interpretation. Transition wasn't allowed. </p>

<p>But I have heard and read statements coming out of the two other camps of thought that share this kind of certainty over interpretation, too. There is a sense of doing injustice to scripture, thereby doing an injustice to Christianity, and, thereby again, doing an injustice to God if one strays from the preferred reading. One Old Earth Creationist remarked in a popular book that an interpretation of Genesis that allows for evolution is a “contradiction in terms” and it's an unfortunate thing to “blame God for it.” Genesis, in the mind of this thinker, specifically precludes any interpretation which leads to the sort of story evolution tells. To think otherwise is to “blame” God for something which he intentionally tells us is otherwise against his nature.</p>

<p>I have equally heard some theistic evolutionists deride—in a very spiritually shallow and personally offensive way—those who do not accept an evolutionary viewpoint. As one who went through an interpretive evolution on biological evolution, I can say confidently that I believe my own transition would have been much easier both intellectually and spiritually if not for feeling as if certain theistic evolutionists accused me of intentionally lying or being mentally ignorant. It seems that all three camps are at least sometimes plagued by the issue of pride—especially in the cases of a few strong advocates. But pride is nothing less than the cement by which interpretive barriers are built, helping them become unmovable walls that protect the interpretive communities within.<sup>1</sup> </p>

<p>On the other hand, one of the great benefits of the fall of positivism (or verificationism) and the rise of postmodernism was the realization that total objectivity among individuals is a false conception. And, since individuals make up communities, neither are camps of thought above error and immune from being wrong. Yet way too many Christians continue to approach Genesis as if we can interpret it on its own terms, completely and totally, without reference to our own location in history and culture. We're still functionally positivists. But it is an illusion that we’re above the interpretive fray, and we must realize time and again that we are subjective individuals, affected by a number of factors and people. We are deeply influenced by those that speak into us, those that we trust, and those that we find credible. As W. Randolph Tate writes, </p>


<blockquote>Interpretations...must be consistent with the established interpretive framework of the interpretive community. The worldview of the interpretive community sets the parameters within which interpretations are accepted or rejected.<sup>2</sup></blockquote>

<p>The Bible takes a slightly different angle and puts it this way: “for all have sinned and fall short of the glory of God.”  In other words, we are not objective data-interpreting individuals but fallen men and women, even as followers of Jesus. </p>

<p>So it’s when groups of folks line up on either side of an issue and make their positions part of their identity that the debate over interpreting Genesis reaches a near stalemate. It's communities against communities, PhDs against PhDs, experts against experts, and—perhaps more internally—interpretive parameters against interpretive parameters. The truth is that as long as we are first and foremost committed to maintaining the community in which we are involved, there will be very little chance of us getting at the real issues and the best conclusions, much less giving an adequate witness to our God, both Creator and Redeemer.</p>


<h3>New eyes, fresh air</h3>

<p>I mentioned earlier that I spent time in all three major camps of thought on this issue. I was a hard-lined Young Earth Creationist, debating on forums and writing creationist papers in college. I argued for the existence of modern-day dinosaurs, major flood geology, and so on. I was convinced I was right, that defending the truth meant digging my heels deeper into the sand. But two questions plagued my thoughts: first, I asked whether Christianity fell to pieces if I was wrong. Second, I asked whether I was committed to Christ or, rather, to myself and my interpretations. With that as my first major paradigm shift, I eventually came to accept an Old Earth view. I sat comfortably within the Old Earth view for several years, but the Lord was still at work in me, and, once again, brought those two questions to my mind.  Back to the books I went, back to the Bible I went, and back to prayer I went.  </p>

<p>Through months of extremely difficult and heart-rending transition, I found myself considering a particular reading of Genesis that I would have regarded as unacceptable as a YEC. But then I was confronted with this even more important point about Christianity: often God finds what is unacceptable to us very acceptable to Him! That included me, personally, and I felt the warmth of God’s grace flow over me. In the wake of that change of heart, people accused me of rejecting my background, my Christian education, and my interpretive communities. And, yet—whether I was right or wrong—I knew God accepted my path towards this new reading of Creation as a genuine search for Him. My spiritual struggle—contrary to what I thought while it was happening—was not a struggle to reject bad data and exegesis, it was a struggle to reject myself. </p>

<p>While the “facts” were important, that spiritual struggle was even more so for me. What was God showing me in the midst of it all? Was thinking differently about the creation making me appreciate the Creator less, or more?  Did reading Genesis differently mean only that I had been wrong, or that it was somehow less true? What did any of this have to do with my sense of calling to love and serve God and my fellow men?   In a way, I’m still figuring this out. But I can absolutely testify that the struggle transformed every single one of these questions. Indeed, for the first time, I believe I saw God as much <em>this-worldly</em> as <em>other-worldly</em>. I saw nature as intimately intertwined with itself, still being woven together by God’s hand. I saw Scripture as a beautiful expression of God’s desire that man should participate in creation. I saw that my fellow men and my fellow Christians were all on a journey, much the way I was. And I saw myself as a flawed, stubborn, and prideful man, yet forgiven for the times I’ve pitted myself and my presuppositions about Scripture against God, its author. </p>

<p>As settled as I am now, I have not forgotten that the common ribbon which ties together all of these transitions is my commitment to keep asking questions within my own circle, too—realizing that God still has much to teach all of us.  I have learned the continuing importance of stepping outside of my camp and making sure I haven’t become merely a product of or a willing prisoner to thinking a certain way, unwilling to consider that it and I might be incorrect. I came to realize that <em>everyone</em> (including myself, of course) has stories and life experiences that become the framework in which they read Genesis 1-2.  And if I stopped pretending that I, myself, could be perfectly objective, then I also had to stop pretending that those in the community that I trusted were <em>necessarily</em> objective, themselves. </p>

<p>Ultimately, I had to be willing to be wrong and to see that my friends might be wrong, too. That’s not something that any of us are “naturally” very good at, but it is possible when we realize that the world does not depend on <em>us</em> being right, but upon Jesus being right. For me, seeking truth rather than presupposition requires that we all be able to approach the communities that have influenced us deeply, and ask not just “what” they say but “why” they say it.  We all have to guard our hearts even more than our heads.  Frequently reminding myself to walk back to the edge of my own camp—to follow Jesus’ example and withdraw to a solitary place—has shown me that there is room to breathe outside our familiar interpretive parameters.  At certain times, I have found it to be the most refreshing air I've ever tasted.</p>

<h3>Notes </h3>

<p class="date">1. Though, admittedly, the theistic evolutionists tend to have a greater sense of leeway when it comes to how the claims of Genesis 1-2 affect Christianity as a whole. It would be an odd thing to say that to <em>not</em> interpret Genesis 1-2 as an evolutionary metaphor is to reject Christianity. As far as I know, most Christian evolutionists are very much willing to acknowledge that Young and Old Earth Creationists are still within appropriate spiritual bounds, even if not scientific ones. It seems to me that if individual theistic evolutionists choose an issue about which to be rigid, it’s the Fall and the existence of Adam.<br />

        <description>The BioLogos Foundation explains to the findings of the Encyclopedia of DNA Elements (ENCODE) project and responds to the claims that its discoveries challenge the theory of evolution, especially regarding so&#45;called &quot;junk DNA&quot;.</description>
        <content:encoded><![CDATA[<p>In 2003, under the leadership of BioLogos founder Francis Collins, the Human Genome Project sequenced the full human genome, showing us for the first time the order of the 3.2 billion chemical “bases” that make up the rungs of DNA’s double helix structure. The project identified and mapped 23,000 genes that code for proteins, but those genes make up less than 2% of the total sequence—far fewer than originally predicted, given the complexity of humans. While many non-coding sequences were identified as having function as well, there were still vast swaths of the genome that had no obvious function. In fact, what was known about certain classes of sequences suggested that they had no functional role for humans—such as the sequences identified as either transposons or transposon fragments that make up nearly half of our genome. These sorts of sequences seemed to fit into what was popularly known as the “junk DNA” category. </p>

<p>With the complete genome sequence in hand, we knew the sequence and location of our genes, but what we didn’t know was how all those genes are regulated: how do the trillions of cells in our bodies know when to turn on or off all those genes?  How do the hundreds of distinct cell types develop and function together, when they are all running on the same DNA “operating system?”  </p>
<p>That’s where the ENCODE (short for Encyclopedia of DNA Elements) project comes in. Launched in September 2003, shortly after the announced completion of the Human Genome Project, the goal of the ENCODE project is “to build a comprehensive parts list of functional elements in the human genome, including elements that act at the protein and RNA levels, and regulatory elements that control cells and circumstances in which a gene is active.” In other words, the project seeks to understand how the genome “works.”</p>

<p>Early this month, researchers from ENCODE released more than thirty papers presenting their findings. During a <em>Science</em> magazine <a href="http://news.sciencemag.org/sciencenow/2012/09/live-chat-figuring-out-what-dna.html">online chat</a>, the project’s data coordinator, Ewan Birney, explained the outcome:</p>

<blockquote>The ENCODE project aimed to start our understanding of how the human genome works. We know that (nearly) all the information that determines a human is in the genome, as we all start off as single cell with this DNA. However, we had a patchy understanding of how it works, in particular away from protein coding genes.<br /><br />

To work out how the genome works, we used the fact there are many tiny machines (proteins and RNA - RNA is very like DNA) in each of our cells which know how to "read" parts of the genome. By monitoring where these little molecular machines are on the genome, or how parts of the DNA are copied into RNA (there are quite a few different types of RNA as well), we start to gain some insight into the genome.<br /><br />

We did many such experiments, across different cell types (eg, one cell type was very similar to a liver cell type; another was very similar to a white blood cell). This way not only can we see what is similar, we can also see differences between these cell types.<br /><br />

There is a lot more to get to know and understand here - this is definitely closer to the start than the end. But it is a substantial amount of data, and analysis, to start on this journey.</blockquote>

<p>According to the abstract of one of the <a href="http://www.nature.com/nature/journal/v489/n7414/full/nature11247.html">lead papers</a> from <em>Nature</em>, this extraordinary glut of data “enabled us to assign biochemical functions for 80% of the genome, in particular outside of the well-studied protein-coding regions.”  Only 2% of the genome codes for proteins, but 80% or more has <em>some</em> biochemical function.  As a <em>Science</em> <a href="http://www.sciencemag.org/content/337/6099/1159">news article</a> put it, these 30 papers “sound the death knell for the idea that our DNA is mostly littered with useless bases.”</p>

<p>The pro-Intelligent Design organization The Discovery Institute has heralded the discovery as the “demise of junk DNA.”  Casey Luskin writes for their <a href="http://www.evolutionnews.org/2012/09/junk_no_more_en_1064001.html">blog</a> <em>Evolution News</em>:</p>

<blockquote>Let's simply observe that it provides a stunning vindication of the prediction of intelligent design that the genome will turn out to have mass functionality for so-called "junk" DNA. ENCODE researchers use words like "surprising" or "unprecedented." They talk about of how "human DNA is a lot more active than we expected." But under an intelligent design paradigm, none of this is surprising. In fact, it is exactly what ID predicted.</blockquote>

<p>The extent to which the ENCODE project been able to identify function has been surprising—even exhilarating—though scientists have for some time been getting glimpses of the many ways in which segments of DNA can be “active.”  Even in 1970 biologists knew that some non-coding DNA had function, and by 2003 there was a large body of work demonstrating that many non-coding elements acted as promoters, enhancers, insulators, and so on. Indeed, in recent years many have come to appreciate the fact that “junk” was never really an appropriate metaphor in the first place.   Still, because sequencing of multiple genomes has shed such extraordinary light on key evolutionary mechanisms, many geneticists have focused on function primarily in terms of which regions do or do not contribute to the evolutionary fitness of their host, rather than whether they were merely "doing something" biochemically.  What the impressive ENCODE project has done is open a treasure trove of new information that can only accelerate the pace at which researchers are able to explore the incredible subtlety and complexity of DNA, and refine the very concept of “functionality.” </p>

<p>So with all this in mind, is ENCODE a stunning victory for ID, as Luskin believes? Bryan College biologist Todd Wood thinks not.  He <a href="http://toddcwood.blogspot.co.uk/2012/09/everyones-excited-about-encode.html">writes</a>, “I don't think that function equates to design, nor do I think that design requires or predicts function.  They're not the same thing… my understanding of function does not require me to hypothesize God (or an anonymous designer, if you must) as the proximal cause.”  </p>

<p>We agree.  Indeed we would go on to say that evolution and design are not mutually exclusive.  So while finding function is not sufficient to prove design, recognizing that function has arisen by way of evolution does not indicate that God was not at work.  We at BioLogos believe God providentially works out his purposes—his designs—<em>through</em> the elegant processes of evolution, not in opposition to them.</p>

<p>Amazing as the new data are, it only strengthens and enhances our evidence for evolution.  While much of the genome is “doing something” biochemically, it is still likely that the majority of the sequence is evolutionarily neutral (Senior Fellow Dennis Venema discusses the evidence for this “neutrality” in a <a href="http://biologos.org/blog/understanding-evolution-is-there-junk-in-your-genome-part-1">post</a> on our site, including a striking comparison between 29 different mammal genomes and the human genome).  In fact, another  ENCODE researcher participating in the <em>Science</em> magazine chat, John A. Stamatoyannopoulos of the University of Washington School of Medicine, thinks the findings align beautifully with evolutionary theory:
</p>

<blockquote>ENCODE's data provide a unique and powerful window through which to view evolutionary change. We can see those changes directly by lining up the genome sequences of many different organisms -- these line-ups have revealed millions of regions where all the genomes agree, indicating sequences that have been specially preserved by evolution while others have decayed away (ie freely changed their letter codes). We now see that a large proportion of these 'conserved' regions are lighted up by ENCODE annotations, indicating that they are marking spots in the genome that contain important instructions for cell function.</blockquote>

<p>We’ve discussed “junk” DNA previously, including a multi-part series by Dennis Venema, and we’ve received many emails over the past few days asking for our comments on the ENCODE findings. On Monday and Tuesday, Dr. Venema will begin to offer his own thoughts on ENCODE.</p>

        <title>Freedom and Grace in Tennessee</title>

        <description>Towards the end of the last school year, the Tennessee legislature passed the Teacher Protection Academic Freedom Act, a law that became more popularly known as the “Monkey Bill.”  I was doing research in a Tennessee high school biology classroom the morning that I learned that the bill had passed.</description>
        <content:encoded><![CDATA[<p>Towards the end of the last school year, the Tennessee legislature passed the <a href="http://biologos.org/uploads/projects/Tennessee_HB0368.pdf">Teacher Protection Academic Freedom Act</a>, a law that became more popularly known as the “Monkey Bill.”  I was doing research in a Tennessee high school biology classroom the morning that I learned that the bill had passed, and as the teacher informed her uninterested class about the details, she made the comment that we are "devolving" in the great state of Tennessee instead of "evolving." As a Christian, a biologist, and a soon-to-be educator, I was inclined to agree.</p>

<p>In Tennessee and across the country, many others weighed in on the subject over the next few weeks, including two essays (<a href="http://biologos.org/blog/teaching-science-in-tennessee">here</a> and <a href="http://biologos.org/blog/teaching-the-whole-controversy">here</a>) on the BioLogos Forum.  But soon after that, other issues crowded that story off the front page. Now, though, teachers and students across my state are returning to science classrooms, and we will all get to see what effect the law has in practice. Again speaking as a Christian, a biologist, and educator and drawing on all three of those perspectives, I’d like to offer my own reflections on the bill’s likely effect on Tennessee teachers and students, beginning with this excerpt from the bill itself: </p>

<blockquote> The teaching of some scientific subjects, including, but not limited to, biological evolution, the chemical origins of life, global warming, and human cloning, can cause controversy . . . The state board of education, public elementary and secondary school governing authorities, directors of schools, school system administrators, and public elementary and secondary school principals and administrators shall endeavor to assist teachers to find effective ways to present the science curriculum as it addresses scientific controversies.  (Tennessee HB368 / SB893)</blockquote>

<p>As an evangelical, I think this bill could be more detrimental than helpful to Christian teenagers’ faith. Many students who are particularly interested in the sciences and theory of evolution are already in the uncomfortable position of hearing pro-Intelligent Design doctrine from the pulpit on Sunday and then listening to their science teacher’s evolution instruction on Monday.  I was one of those students—sitting in more than one congregation under pastors who were particularly antagonistic to the theory of evolution, and who made not-so-subtle comments that it cannot co-exist with authentic Christian faith. Having a keen interest in the sciences and wanting to explore the data so widely accepted by the scientific community, I felt confused and ostracized in my church. I wondered if I would have to choose between my faith and intellectual integrity. The church family I trusted clashed with the science that I also trusted, causing a near catastrophe for my faith. I am thankful to the few people who offered me grace, allowing for my questioning of some of what I heard in church without labeling me a heretic. </p>

<p>Though the conservative Christian community may view this bill as a “win for the faith,” it is actually a loss if it reinforces the idea that this is simply an issue of science vs. scripture. Evolution is central to modern biology; trust in the authority of the Scriptures is central to Christian faith.  But this fight mentality between the two established communities is detrimental to our young teenagers who are seeking to grow in faith, but who cannot seem to reconcile scripture and scientific data.  We need them to seek after that reconciliation, not be told it can’t be done. Whatever they are hearing from the pulpit, the science classroom should be the one place that students can learn science. Students may well emerge with bitterness towards the church for dismissing the evidence of evolution not only so quickly, but in what is so often a haughty and condescending manner. Worse yet, students may emerge with bitterness that they were forced to choose between faith and intellectual integrity. Is this really an all or nothing argument? Are the two truly diametrically opposed?</p>

<p>In my world, these two have reconciled, and they now co-exist in peace. It has been a very long road to get there and I could not have done it without both access to good data and the freedom to explore it.  Having taught teenagers in an evangelical church for years and having observed in many biology classrooms as well, I know that many students are still struggling for this same reconciliation. That reconciliation is perhaps most easily attained when the seeking student is able investigate evolution in the science classroom without harassment from opposing religious forces. With this freedom, the student may very well realize that the fear that he/she may have regarding evolution is really just a fear of the unknown, and that it is possible to have intellectual integrity and to praise God for initiating and sustaining the evolutionary process.</p>

<p>In Tennessee’s science classrooms there are surely many teachers who begrudge being told that they <em>must</em> teach evolution, and who are relieved that they can now present it as a controversy and/or allow Intelligent Design as an alternative. They, too, will likely see this law as a “win.” But isn’t public science education is about giving students an accurate picture of the state of science, not about teachers’ philosophical opinions? As has been pointed out before, most Tennessee science teachers have not had the training to teach about religion or philosophy; they have been trained to teach about the basic principles of the biological world. </p>

<p>This bill may be particularly frustrating, then, to teachers who do simply want to teach science. From the many hours I’ve spent in secondary biology classrooms this year, I can say for sure that time is of the essence.  Tennessee teachers have barely enough instructional time to cover what students must know to pass the end-of-course biology test required for graduation; they do not have extra time to spend covering material that is not science. I have seen classroom arguments over evolution’s feasibility that ate away precious instruction time and only left a greater rift between the two camps and no doubt, a frustrated teacher. News of the Intelligent Design movement’s success in creating political and legal controversy is misplaced content in the secondary biology classroom. </p>

<p>Furthermore, as it allows teachers to frame biological evolution in terms of “controversy”— something that is a topic for debate—this law will likely not result in students who are more engaged in understanding science, but instead, only in more confusion (and possibly antagonism) in the classroom. Educators welcome debate in many cases because debate encourages critical thinking that leads to “formal thought,” the Holy Grail of Piaget’s Theory of Cognitive Development.  But the practice of science is about proposing hypotheses and testing the data, not primarily argumentation. And if the science community is not “debating” evolution, why should high school science students be debating evolution as part of their biology curriculum? </p>

<p>The bill is correct in stating that the purpose of science education is to “inform students about scientific evidence” and “help students develop critical thinking skills necessary to becoming intelligent, productive, and scientifically informed citizens.” I certainly agree, though I question whether it needed to be legislated.  Rather, my answer is: “Let’s actually do it!” Before bringing “debate” and “controversy” about scientific theories into the classroom, let’s instead teach our students about sound scientific practice; let’s give them opportunities to learn how to research and to employ the scientific method in everyday life. Let’s focus on teaching them about observing the indicators of climate change, the intricacies of DNA, conservation of ecosystems, and the principles of molecular and cell biology. Let’s give them the tools—specific to science— that help them think critically and work out problems, rather than undermining faith in those very practices and the community of people that uses them every day.  Let’s <em>not</em> teach them to live in denial of the ordinary dependability of science, let’s <em>not</em> teach them to distrust scientists who have no interest in “debate,” but want to understand the world God made.</p> 

<p>In Tennessee and elsewhere, let’s give both our students and those scientists the grace and support they need to merge authentic faith and intellectual integrity. </p>

        <title>The Questions Update: How have Christians responded to Darwin’s “Origin of Species”?</title>

        <description>History reveals that one of the earliest supporters of evolutionary theory in the American scientific community was a devout Christian botanist named Asa Gray. And among theologians, BB Warfield believed that certain forms of evolution were also compatible with a high view of Scripture.</description>
        <content:encoded><![CDATA[<h3>Introduction</h3>
<p>Many believe that before Darwin published <em>The Origin of Species</em> in 1859, Christians as a whole maintained an entirely literal, six-day interpretation of Genesis in which the earth was only a few thousand years old. In fact, however, the idea of an old earth had already become increasingly popular among Christians throughout the half century leading up to <em>The Origin of Species</em>. <a href="#note-1"><sup>1</sup></a></p>
<p>Another misconception is that the arrival of Darwin’s theory led the scientific and theological communities to immediately take up positions opposing each other. But history reveals that one of the earliest supporters of evolutionary theory in the American scientific community was a devout Christian botanist named Asa Gray.  And among theologians, BB Warfield—an architect of the contemporary evangelical understanding of biblical inerrancy—believed that certain forms of evolution were also compatible with a high view of Scripture.</p>

<h3>The First Christian Response to <em>Origin of Species</em> in America</h3>
<p>Darwin did not invent the idea of evolution. By the time <em>The Origin of Species</em> was published, the idea of evolution in many natural processes was already popular, and the term <em>development</em> was used in its place for discussions of society’s change or the history of the solar system.<a href="#note-2"><sup>2</sup></a> What’s more, it was widely accepted that the earth was much older than previously thought. Most of the groundwork for this understanding resulted from geological work done earlier that century. Through meticulous study of the fossil record, naturalists helped spread the view that the earth was old rather than young. </p>

<div class="see-also"><img src="http://biologos.org/uploads/static-content/ages_earth_thumb.jpg" height="76" width="70">See <a href="http://biologos.org/questions/ages-of-the-earth-and-universe">How are the ages of the earth and universe calculated?</a></div>

<p>Though many people like to focus on Christian hostility to evolutionary theory, a careful look at history reveals some surprising facts.  For instance, the first American scientist to carefully review and publically support Darwin’s <em>Origin of Species</em> was a devout Christian named Asa Gray, now regarded as one of the most prominent American biologists of the 19<sup>th</sup> century.  A shy person who avoided politics, Gray worked quietly and does not have the same name recognition as scientists like Louis Agassiz and T.H. Huxley—both flamboyant self-promoters who provoked public debate. But, his brilliant research during his 30-year career at Harvard University helped usher in the era of modern biology in the United States. </p>

<p class="caption-center"><img src="http://biologos.org/uploads/static-content/asa_gray.jpg" alt="" height="409" width="570"  /><br />Source: http://www.huh.harvard.edu/libraries/Gray_Bicent/images/gray_1325.jpg</p>

 
<p>Asa Gray made his commitment to Christ in 1835, a few years after completing medical school (much like Francis Collins of our own era). <a href="#note-3"><sup>3</sup></a> As a professing Christian, Gray was a committed churchgoer and member of a local congregation in Cambridge, Massachusetts.  As a professional scientist, he insisted that science was neutral in matters of religion and metaphysics. Gray found evolutionary theory incredibly stimulating to his scientific research, but never found it threatening to his faith.  Both before and after reading <em>Origin of Species</em>, Gray remained firmly grounded in the <a href="http://www.crcna.org/pages/nicene_creed.cfm">Nicene Creed</a>, a profession of faith that Christians have shared since the early Church.  <a href="#note-4"><sup>4</sup></a></p>

<p>What happened when <em>Origin of Species</em> burst onto the scene?  Gray’s extensive research on American and Japanese plants—which he published after corresponding with Charles Darwin—had already convinced him that species and genera found in both countries resulted from common ancestry, not separate creations.  He responded to Darwin’s book by writing the first major review<a href="#note-5"><sup>5</sup></a> of <em>Origin</em> on his side of the Atlantic, and he defended Darwin’s scientific theory in a series of meetings of the American Association for the Advancement of Science in 1859 and 1860.  Gray was determined that <em>Origin</em> would get a fair reading from the scientific community, and he even took a leading role in negotiations to reprint <em>Origin</em> in the United States in 1860, ensuring that Americans could have the most accurate edition in their hands. </p>

<p>Regarding the theological implications of evolution, Gray believed that Darwin’s theory was not atheistic, although he recognized that some would use it as an “excuse” for unbelief.  Henceforth, he concluded, we need “to reshape” the argument from design “in such wise as to harmonize our ineradicable belief in design with the fundamental scientific belief of continuity in nature, now extended to organic as well as inorganic forms, to living beings as well as inanimate things.” The question of whether or not life evolves should not be confused with the issue of God’s existence.  Instead, Gray thought that each issue should be investigated using methods appropriate to the subject of inquiry.  His refusal to argue for either extreme in this contentious debate upset both anti-evolutionists and radical popularizers of science, both of whom were eager to believe that evolution implied atheism.<a href="#note-6"><sup>6</sup></a></p>

        <description>Many Christians believe that they face a painful choice&#45;&#45; either life was designed by God or it is an evolutionary product of natural selection.  Charles Darwin himself believed in this dichotomy, and people ever since have felt the need to &quot;choose sides&quot;.  However, looking back at history, we find that one of Darwin&apos;s chief scientific colleagues, Asa Gray, did not share this perspective. In this three&#45;part essay, part 1 charts the relationship of Asa Gray and Charles Darwin.  Part 2 describes Darwin&apos;s struggle with the problem of natural evil and design in nature, and part 3 explores how Asa Gray was able to embrace evolution without rejecting the idea of design.</description>
        <content:encoded><![CDATA[<h3>Asa Gray</h3>

<p class="caption-left"><img src="http://biologos.org/uploads/static-content/asa_gray_image_3.jpg" alt="" height="374" width="250"  /><br />Asa Gray</p>

<p>If Thomas Huxley earned the title of "Darwin's bulldog," then Asa Gray should be remembered as "Darwin's dove." Whereas Huxley enjoyed a good fight in his defense of Darwin's theory, Gray sought to mediate and bring sides together around a common understanding of "good science." As Darwin's strongest and most vocal scientific ally in the United States, Gray recognized the scientific importance of Darwin's efforts for the growing professionalism of biological researchers.</p>

<p>But as an orthodox Christian, a Presbyterian firmly devoted to the faith expressed in the Nicene Creed, Gray saw in Darwin's theory both evidence for his philosophical commitment to natural theology and support for his opposition to the idealism advocated by Louis Agassiz and the <em>Naturphilosophen</em> in both Europe and America. Indeed, Agassiz's advocacy of Platonic forms as a basis of biological understanding (e.g., "A species is a thought of the creator")<sup>1</sup> would be a major source of American opposition to Darwin's theory.</p>

<p>Professor of botany at Harvard during most of the middle half of the nineteenth century, Gray was one of the few members of the scientific community to whom Darwin revealed his theory before the publication of <em>On the Origin of Species,</em> and, from what I can tell, the only American. Gray and Darwin met briefly in January 1839 during one of Gray's visits to England. Later, during the 1850s, Darwin wrote Gray on several occasions requesting information--a practice that Darwin frequently employed.  In 1854, Darwin's friend and confidant, Joseph Hooker, showed Darwin Gray's review of Hooker's <em>Flora of New Zealand</em>, in which Gray had argued strongly against Louis Agassiz's idealism and had raised questions from his own work on the stability of species. Gray was not yet ready to deny their permanence, but hybrids and other observations were beginning to trouble him.</p>

<p>The next year Gray wrote a lucid and penetrating positive evaluation of Alphonse De Candolle's two-volume <em>Géographie botanique raisonnée</em>, a pioneering work dealing with plant geography and distribution from a statistical perspective. Hooker had sneeringly dismissed the work. In A. Hunter Dupree's authoritative biography of Gray, he describes Gray's puzzlement at Hooker's response in these terms:</p>

<blockquote>Although in the long view Gray's evaluation of the epoch-making nature of De Candolle's book was more justified than Hooker's sneers, [Gray was confused by his response, for] Hooker seemed to be talking with a more comprehensive theory definitely in mind, some reason for taking his position, which he did not divulge and which his friend [Gray] did not possess.<sup>2</sup></blockquote>

<p>Darwin, however, saw in both Gray's review of Hooker's book and in his comments on De Candolle's tome that Gray was troubled by some of the same empirical data that had been bothering him. In April 1855, Darwin wrote Gray to urge that Gray update his <em>Manual of the Botany of the Northern United States</em> first published in 1848, and especially to address the issue of the range of Alpine plants in the United States. Specifically, he said: "Now I would say it is your duty to generalise as far as you safely can from your as yet completed work."<sup>3</sup></p>

<p>Behind this request was Darwin's desire to test his impression that Gray could make a good ally. Gray passed the test, and finally, in July 1857, Darwin let Gray in on his theory of the transmutation of species. Gray was never an uncritical supporter, and there are many evidences in the correspondence between these two scientists that Gray was willing to challenge Darwin and disagree with some of his conclusions. Nevertheless, Gray saw the importance of Darwin's work and the ways in which it provided answers to the troublesome issues that he had confronted in his own botanical efforts.</p>

<h3>Gray responds to Darwin's theory</h3>

<p>After considerable interchange--one might even say debate--among Gray, Darwin, and Hooker, Gray wrote to Hooker in October 1859 (one month before the publication of <em>On the Origin of Species</em>) saying that he had absolutely no problem with cognate species arising by variation. He did, however, raise a concern that would be the source of much future discussion. He wondered about Darwin's "carry[ing] out this view to its ultimate and legitimate results,--how [do] you connect the philosophy of religion with the philosophy of your science." He added: "I should feel uneasy if I could not connect them into a consistent whole--i.e., fundamental principles of science should not be in conflict."<sup>4</sup></p>

<p>When <em>Origins</em> was published, Gray wrote a clear, positive, yet critical review in <em>The American Journal of Science</em>. Aware of mounting religious opposition, he ended his review by arguing that whereas one could use Darwin's theory in support of an atheistic view of Nature, one could use any scientific theory in that way. He wrote:  "The theory of gravitation and ... the nebular hypothesis assume a <em>universal and ultimate</em> physical cause, from which the effects in nature must necessarily have resulted."<sup>5</sup> He did not see the physicists and astronomers who adopted Newton's theories as atheists or pantheists, though Leibniz earlier had raised such reservations.  And a similar situation existed with the origin of species by natural selection.  Darwin, Gray continued: "merely takes up a particular, proximate cause, or set of such causes, from which, it is argued, the present diversity of species has or may have contingently resulted. The author does not say necessarily resulted."<sup>6</sup></p>

<p>This far Gray could go with Darwin. But there was a point at which he parted company, and that was the fortuitous <em>randomness</em> of the process that Darwin's theory seemed to imply.</p>

        <description>Considering the immense popularity of &quot;Darwin&apos;s finches&quot;, it is quite surprising to learn that Charles Darwin himself had very little to say about them. In fact, it was actually David Lack, one century later, who conducted the critical research that immortalized the finches in biology textbooks and popular lore.</description>
        <content:encoded><![CDATA[<h3>Darwin’s Finches? </h3>

<p>Darwin’s finches are some of the most visible and recognizable symbols of evolution in the world today.  Biology textbooks feature them prominently, and the National Academy of Sciences has enshrined them in the entrance of their headquarters in Washington, DC.  Surely the finches that Darwin collected on the Galápagos islands were a central feature of his evolutionary theory, right?</p>

<p class="caption-left"><img src="http://biologos.org/uploads/static-content/Lacks_Finches_NASlobby.jpg" alt="Lobby of the National Academy of Sciences" height="350" width="570"  /></br>Lobby of The National Academies Building.  Courtesy of CPNAS. Photo by Robert Lautman</p>

<p>Actually, the Galápagos finches are never even mentioned in Darwin’s famous work <em>On the Origin of Species</em>.  Nor do they appear in Darwin’s famous notebooks on “Transmutation of Species”, in which he formulated the idea of evolution by natural selection.<sup>1</sup>  Even Darwin’s private diary of his voyage on the HMS <em>Beagle</em> only mentions the Galápagos finches briefly in passing.<sup>2</sup> </p> 

<p>It was only in 1845, in the second edition of <em>The Voyage of the Beagle</em>, that Darwin included a tantalizing sentence about the Galápagos finches:</p>

<blockquote>Seeing this gradation and diversity of structure in one small, intimately related group of birds, one might really fancy that from an original paucity of birds in this archipelago, one species had been taken and modified for different ends.<sup>3</sup>
</blockquote>

<p>However insightful this statement may have been, Darwin never published anything else about the Galápagos finches for the rest of his life.  Nor did he publically present these birds as direct evidence for this theory of evolution.<sup>4</sup> 
</p>

<p>If these finches were so important to Darwin’s evolutionary theory, why did he remain silent about them?  One of his comments in <em>The Voyage of the Beagle</em> provides us with a clue:</p>

<blockquote>Unfortunately most of the specimens of the finch tribe were mingled together; but I have strong reasons to suspect that some of the species of the subgroup Geospiza are confined to separate islands.<sup>5</sup> </blockquote>

<p>When Darwin was exploring the Galápagos himself in 1835, he had not formulated his theory of evolution yet, and thus he did know what data would be necessary to make definitive conclusions about finch evolution.  In particular, he did not keep careful track of which of his specimens came from which islands.   Moreover, as was customary among naturalists at that time, Darwin only collected a small number specimens—he brought home only 31 finches and 64 total birds from the Galápagos.<sup>6</sup>   </p>

<p>Though Darwin sensed that these birds were truly special, he lacked sufficient evidence to reach any specific conclusions about their evolutionary origins.  It would be up to the rest of the scientific community to carry out the necessary empirical research.  Subsequent expeditions in 1868, 1891, 1897, and 1905 brought back thousands of Galápagos finch specimens, but instead of unlocking the mysteries of evolutionary theory, the Galápagos finches became a great enigma.<sup>7</sup>  </p>

<p>A century after Darwin's voyage, scientists still struggled to explain the staggering variety of finches on this tiny, remote archipelago.  By the mid-1930’s, British Museum ornithologist Percy Lowe argued that the finches presented a "biological problem of first class importance", and he told the British Association for the Advancement of Science that the finches displayed a "bewildering diversity, intergradation, and distribution".<sup>8</sup>   Who would be up to the challenge of making sense of such tremendous biological complexity? It was David Lack.</p>
 
<h3>David Lack</h3>

<p class="caption-right"><img src="http://biologos.org/uploads/static-content/David_Lack.png" alt="Ornithologist David Lack" height="291" width="250"  /></br>Ornithologist David Lack</p>

<p>David Lack had an exceptionally keen eye for bird-watching, and he possessed a passion to match it.  By age 15, he had already observed 100 distinct species of birds, and before entering college, authored his first scientific paper.  At Cambridge University in the early 1930’s, Lack was disappointed to find that his zoology professors taught “nothing about evolution, ecology, behavior or genetics, and of course nothing about birds.”<sup>9</sup>  In fact, at that time, there were only two professional ornithologists in all of Britain!</p>

<p>Thus David Lack took it upon himself to create his own learning opportunities.   As an undergraduate, he became the president of the Cambridge Ornithological Club, traveled to Greenland for a bird-watching expedition, and cultivated a relationship with the prominent biologist Julian Huxley (grandson of Thomas Henry Huxley).  Huxley was an inspiring mentor and encouraged Lack to expand his research further by studying tropical birds.<sup>10</sup>  Following this advice, Lack embarked on a research trip to Tanzania in the summer of 1934, but his greatest adventure was yet to come. </p>

<p>In 1937, Lack became fascinated by the scientific mysteries surrounding the Galápagos finches.  But in order to study their behavior, Lack would need to travel to remote islands halfway around the world.   How could he possibly get there?  Once again, Julian Huxley was tremendously supportive and raised funds from two prominent scientific societies to pay for his expedition.  After a long delay, David Lack and five companions finally set off on their journey.</p>

<p>Instead of residing in comfortable quarters aboard a royal naval ship, Lack’s group subsisted on a shoestring budget, traveled on commercial steamers, and stayed with local settlers.  Their experience was definitely not a romantic tale of imperial expedition:</p>

<blockquote>The Galápagos are interesting, but scarcely a residential paradise.  The biological peculiarities are offset by an enervating climate, monotonous scenery, dense thorn scrub, cactus spines, loose sharp lava, food deficiencies, water shortage, black rats, fleas, jiggers, ants, mosquitoes, scorpions, Ecuadorian Indians of doubtful honesty, and dejected, disillusioned European settlers.<sup>11</sup></blockquote>

<p>Whereas Charles Darwin spent only nineteen days on the shores of the Galápagos, Lack and his crew conducted more than five months of meticulous and exhausting study in the harsh climate.  At that time, even the finches themselves provided little solace.  Lack wrote,</p>
	
<blockquote>Darwin’s finches are dull to look at, not only in their orderly ranks in museum trays, but also when they hop about the ground or perch in the trees of the Galápagos, making dull unmusical noises.  Only the variety of their beaks and the number of their species excite attention.<sup>12</sup> <strong></strong></blockquote>

<p class="caption-left"><img src="http://biologos.org/uploads/static-content/Lacks_Finches_Cactus_Finch.jpg" alt="Large Cactus Finch–the Galapagos." height="215" width="320"  /></br>Large Cactus Finch on Española Island in the Galápagos Islands</p>

<p>The repetitive tedium requisite for important scientific discoveries is rarely discussed in public, and even today many bright-eyed science students become disillusioned by the painstaking work demanded by their Ph.D. programs.  But one of the things that distinguishes great scientists is their unwavering commitment and tenacity in completing major projects. David Lack's efforts were not in vain: </p>

<p><em>"Despite his personal discomforts (or perhaps because of them), Lack did see something on the Galápagos that no one had ever seen before—natural selection at work among its finches through interspecies competition."</em> <sup>13</sup></p>

<p>When the birds’ breeding season ended in 1939, Lack was ready to return to his home in England.  But the captive finches that he had brought with him fared so badly on the voyage home that he detoured to San Francisco and put them in the care of the California Academy of Sciences.  Turning this mishap into an opportunity, Lack stayed there for five additional months to study the Academy’s enormous  collection of Galápagos finch specimens.<sup>14</sup> </p>

<p>To complete his systematic research, Lack then travelled across the United States to study the Galápagos finch collection housed at the American Museum in New York.<sup>15</sup>   Altogether, Lack examined more than 8000 specimens and specifically measured the length, width, and depth of all their beaks.<sup>16</sup> </p>

<p>Lack’s final obstacle was in getting his research published.  Though he completed his academic manuscript “The Galápagos Finches—A Study in Variation” in 1940, paper shortages during World War II delayed its publication by the California Academy of Sciences until 1945.  Were he only interested in making an original contribution to science, Lack could have stopped here and congratulated himself on a job well-done.  However, his motivation sprung from a deeper source:</p>

<p class="caption-right"><img src="http://biologos.org/uploads/static-content/Lacks14finches_sm.jpg" alt="David Lack's illustration of 14 Finches" height="455" width="300" /> </br>David Lack's drawing of 14 species of Galápagos finches, p. 19 of <em>Darwin’s Finches</em></p>

<p><em>"I did not watch birds primarily for scientific reasons but for sheer enjoyment, and from the age of 15 onward returned day after day in a glow of excitement after seeing a new bird or a new habit."</em> <sup>17</sup></p>

<p>Lack’s joyful fascination with the Galápagos finches inspired him to continue developing his conclusions long after returning from his expedition.  While waiting for his academic paper to be published, he began writing a book that would enable students and the general public to share his excitement about these remarkable birds and the evolutionary processes that shaped them.</p>

<p>First published in 1947, Lack’s book became tremendously influential.  Before this time, biology textbooks had never even mentioned the Galápagos finches.  But after David Lack’s study, the finches became a primary example of evolution by natural selection, specifically <a href="http://en.wikipedia.org/wiki/Adaptive_radiation">adaptive radiation</a>.  Not only did textbooks fully rely on Lack’s findings, they also followed his lead in calling them “Darwin’s finches”, the title of Lack’s famous book.<sup>18</sup> </p>

<h3>Iconic Finches</h3>

<p>What was it about these birds that made them such a prominent symbol of evolution?  As Darwin himself pointed out, the numerous Galápagos finch populations each have distinctive beaks, and he speculated that they could have evolved from an ancestral species that came to the islands.  But a complete picture of finch evolution would have to wait another hundred years, when David Lack arrived.</p>

<p>During his five months on the Galápagos, including both the rainy and dry seasons, Lack observed that these beak differences enable the finches to subsist on different kinds of food:</p>

<blockquote>The beak differences between most of the genera and subgenera of Darwin's finches are clearly correlated with differences in feeding methods.  This is well borne out by the heavy, finch-like beak of the seed-eating <em>Geospiza</em>, the long beak of the flower-probing <em>Cactornis</em>, the somewhat parrot-like beak of the leaf, bud, and fruit-eating <em>Platyspiza</em>, the woodpecker-like beak of the woodboring <em>Catcospiza</em>, and the warbler-like beaks of the insect-eating <em>certhidea</em> and <em>Pinaroloxias</em>.<sup>19</sup>  </blockquote>

<p class="caption-left"><img src="http://biologos.org/uploads/static-content/finchbeaks_sm.jpg" alt="" height="270" width="350"  /> </br>Lack's image of beak adaptations from <em>Darwin’s Finches</em></p>



<p>Specializing in such different sources of food enables these finches to live in close proximity without directly competing with each other or driving populations to extinction.  The fact that so many of these closely related finches are able to co-exist is a remarkable fact in itself.  As Lack himself put it, “It is not only the origin, but also the persistence, of new species which require explanation.”<sup>20</sup> </p>

<p>But it is also fascinating to consider how these birds got to be so different in the first place.  How did a finch come to have a beak like a “parrot”, “woodpecker”, or “warbler”?  The answer lies in the distinct characteristics of the Galápagos.  Because the islands are so remote, no actual parrots, woodpeckers, or warblers ever settled on it.  In the absence of these species, the Galápagos finches were able to adopt feeding habits and forms that they would never have taken on a large continent full of other birds competing for food.  The isolation of these islands offered just the right conditions for us to see living examples of adaptive radiation.<sup>21</sup> </p>

<h3>Conclusion</h3>

<p>Considering the immense popularity of the Galápagos finches, it is quite surprising to learn that Charles Darwin himself had so little to say about them.  In fact, it was actually David Lack, one century later, who conducted the critical research that immortalized the finches in biology textbooks and popular lore.  By naming his landmark book <em>Darwin’s Finches</em>,<sup>22</sup>  Lack paid homage to the man whose voyage on the HMS Beagle helped transform the study of natural history.  But at the same time, Lack also obscured the fact that evolutionary biology is an enterprise conducted by a large community of brilliant scholars, not just the product of one man’s efforts.</p>

<p>This tendency to immortalize “great men of science” has also led many people to refer to modern evolutionary theory as <em>Darwinism</em>, despite the fact that it has substantially changed and developed over the past 150 years.  It is important to give credit where credit is due, and if that’s the case, we should seriously reconsider how we refer to the Galapagos finches.  Evolutionary biologist Dolph Schluter, who studied the finches several decades after David Lack, had this to say:</p>

<blockquote>I find Lack's intuition really stunning given how little information he had.  He's my hero actually… They should be called Lack's finches.<sup>23</sup></blockquote>

<p class="intro">In the second part of this series, we’ll explore the fact that David Lack, in addition to being a world-renowned evolutionary biologist, was also a devout Christian.  His study of evolutionary theory did not cause him to lose his faith; in fact, he actually <em>converted</em> to Christianity after completing his Galápagos finch research.</p>

<h3>For Discussion</h3>
<strong>We’ve seen in this essay that the term “Darwin’s finches” is misleading, especially since Charles Darwin himself didn’t make the Galapagos finches famous.  Is it also problematic that people refer to modern evolutionary theory as “Darwinism”?  What misunderstandings can arise by associating an entire field of science with just a single person?

        <description>Our desire to engage in gracious dialogue with fellow believers who reject biological evolution has been receiving increased attention in both the Christian and secular press.  More importantly, we are being joined in this reconciling project by our brothers and sisters in Christ who have often been defined primarily as our “opponents”.</description>
        <content:encoded><![CDATA[<p>There are two main reasons why it is critically important that science & faith conversations between Christians be conducted with grace and humility.  First, as all of us see “through a glass darkly,” we need the insights of the entire Christian community (from scientists, to theologians, to Biblical scholars, to pastors to poets) in order to achieve the best understanding of the world God called us to cultivate and rule as his regents. No one discipline or perspective is sufficient in itself, whether focused on God’s Word or God’s world.</p>

<p>But it is also important that we engage believers who disagree with us (on human origins, especially) with charity and humility as a witness to our common identity in Christ—that we may be known by our love for each other in tandem with our demonstrated love for the secular world that does not yet claim Christ as Lord and Savior.</p>  

<p>While the BioLogos Foundation is committed to both of these aspects, we are especially pleased that our desire to engage in gracious dialogue with fellow believers who reject biological evolution has been receiving increased and very favorable attention in both the Christian and secular press.  More importantly, we are being joined in that reconciling project by those who have often been defined primarily as our “opponents,” rather than as brothers and sisters in Christ.</p>

<p>First, <a href="http://www.christianitytoday.com/ct/2012/july-august/a-tale-of-two-scientists.html?paging=off">A Tale of Two Scientists</a>, the cover story of Christianity Today’s July-August 2012 issue, featured the accounts of BioLogos Foundation President Darrel Falk and Todd Wood, Director of the Center for Creation Research at Bryan University.  Though Wood does not accept biological evolution on theological grounds, both men recognize its strength and explanatory power. But more importantly, both reject the warfare model between science and faith (and between Christians who think differently) as being, in Wood’s words, “detrimental to the Church.” </p>

<p>Second, our Southern Baptist Voices series has become a model for how such dialogue can be pursued, even in the sometimes no-holds-barred context of the web.  Several installments in our ongoing dialogue with Southern Baptist theologians have been covered by the Erin Roach of the Baptist Press (on <a href="http://www.bpnews.net/bpnews.asp?id=37901">May 25th</a> , <a href="http://www.bpnews.net/bpnews.asp?id=37981">June 6th</a>, and <a href="http://www.bpnews.net/bpnews.asp?id=38198">July 3rd</a>) and on on July 19th by Lillian Kwan of the <a href="http://www.christianpost.com/news/evangelicals-debate-theistic-evolution-historical-adam-78570/">Christian Post</a>.  And just this past week, Associated Press reporter Travis Loller highlighted the series in an article picked up by the <a href="http://www.huffingtonpost.com/2012/07/18/evangelical-scientists-debate-evolution_n_1683480.html">Huffington Post</a>, the <a href="http://www.washingtonpost.com/national/health-science/evangelical-scientists-debate-evolution-online-with-southern-baptist-seminary-professors/2012/07/18/gJQAqBsstW_story.html">Washington Post</a>, and many other news outlets across the country. </p>

<p>To make it easier for readers to find the entire Southern Baptist Voices series and join in the conversation themselves, we’ve launched a new landing page here: <a href="http://biologos.org/blog/sbv">Southern Baptist Voices</a>.  It is our hope and prayer that this initiative will set the stage for future dialogue between evolutionary creationists and those who hold other perspectives, as well.</p>

        <description>One of the challenges for discussing evolution within evangelical Christian circles is that there is widespread confusion about how evolution actually works. In this installment, we examine evidence that proteins in irreducibly complex (IC) systems can form and refine new interactions through gradual mechanisms.</description>
        <content:encoded><![CDATA[<h3>Something old and something new; something borrowed and spliced into</h3>

<p>In the last post in this series, we introduced a paper by Chen and colleagues that sought to identify new genes in various <em>Drosophila</em> (fruit fly) species. The youngest (i.e. the most recently evolved) gene they found is one specific to <em>Drosophila melanogaster</em>, the species of fruit fly beloved by geneticists as a model organism. The gene is named “p24-2” (not the most imaginative name, but it serves its purpose) and the gene it is duplicated from is called “Éclair”. The Éclair gene is found in a number of <em>Drosophila</em> species.  A simplified “family tree” of three <em>Drosophila</em> species  (<em>D. melanogaster, D. simulans and D. erecta</em>) is shown below. The duplication event that generated the p24-2 gene happened within the lineage leading to <em>D. melanogaster</em>, but after <em>D. melanogaster</em> and <em>D. simulans</em> separated as distinct species: </p>

<p align="center"><img src="http://biologos.org/uploads/static-content/Venema_UEIC2_1.png" alt="" height="342" width="500"  /></p>

<p>Since the entire genomes of these species are now sequenced and available online, it is possible to look at the chromosome region where the Éclair gene is found in all three. By looking at this region in <em>D. melanogaster</em>, we see that the brand-new p24-2 gene is almost right next door to its “parent” gene, Éclair. Below is a screen shot taken when looking at this region using a <em>Drosophila</em> “<a href="http://flybase.org/cgi-bin/gbrowse/dmel/?Search=1;name=FBgn0260463">genome browser</a>”  that is freely available online. The red arrow indicates the Éclair gene, and we can see p24-2 is just one gene over, and seems to be nested within another gene called “Unc-115b”. The green arrows are pointing to two different “versions” of how p24-2 is made into an mRNA working copy. The Unc-115b gene (blue arrow) has five different mRNA versions. (One of the p24-2 mRNA versions has a lot of Unc-115b sequence that is not used when the p24-2 protein is made).  </p>

<p align="center"><a href="http://biologos.org/uploads/static-content/Venema_UEIC2_2_large.png"><img src="http://biologos.org/uploads/static-content/Venema_UEIC2_2_small.png" alt="" height="285" width="570"  /></a><br />(Click Image to Enlarge)</p>

<p>Finding a duplicated gene next door to the sequence it is copied from is pretty common in genomes – when chromosomes are copied or recombined during cell division, side-by-side copies of parts of chromosomes show up every now and then. It’s also not surprising to see a new gene cobbled together with another gene. In this case, Unc-115b and p24-2 are overlapping but separate functional entities: they each have their own protein sequences, but each includes the code of the other as a sequence that does not actually translate into protein. The details of how this “cobbling” happens aren’t important for this discussion, other than to note that the mechanisms are known and not rare.  In the chart above, then, the orange sections indicate the active parts of the transcribed sequence, while the gray are sections that are included in the RNA molecule, but do not get used directly to code for the new protein. </p>

<p>When we look at this same chromosome region in <em>D. simulans</em> and <em>D. erecta</em>, however, p24-2 is missing. Éclair and Unc-115b are there, but p24-2 is not, since it arose after <em>D. melanogaster</em> separated from its common ancestors with the other species. (Note: this entire region is a mirror image in <em>D. simulans</em> and <em>D. erecta</em> when compared to <em>D. melanogaster</em> due to a large scale chromosome inversion that covers this whole area. So, while it looks “backwards” compared to the image above, that is not surprising, it’s expected):  </p>

<p align="center"><a href="http://biologos.org/uploads/static-content/Venema_UEIC2_3_large.png"><img src="http://biologos.org/uploads/static-content/Venema_UEIC2_3_small.png" alt="" height="255" width="570"  /></a><br />(Click Image to Enlarge)</p>

<p>So, with the p24-2 gene in <em>D. melanogaster</em>, we have a bona-fide, recent gene duplication event. This gene is brand new, evolutionarily speaking (less than 3 million years old, given the calculated speciation times of <em>D. melanogaster</em> and <em>D. simulans</em>). Not only is it brand new, it is also essential for survival in <em>D. melanogaster</em>: if you remove it, the fly dies. Obviously, since every other <em>Drosophila</em> species lacks p24-2, this gene is not essential for survival for any other species. It’s new, and now it’s necessary.  </p>

<h3>Do new, essential genes refute the Intelligent Design (ID) argument from Irreducible Complexity (IC)?</h3>

<p>So far, nothing we have discussed explicitly threatens the ID argument from IC, though it does threaten the ID argument that new information cannot arise through evolution, a topic we have discussed in detail <a href="http://biologos.org/blog/series/origin-information-series">before</a>. Michael Behe, the main ID proponent of the argument from IC, has <a href="http://behe.uncommondescent.com/2011/01/even-more-from-jerry-coyne/">commented</a> on this research by Chen and colleagues (thanks to commenter “Bilbo” for pointing this out). Behe’s rejoinder was to a blog post by biologist and atheist blogger Jerry Coyne, who used the paper by Chen and colleagues to attack Behe’s ideas. Since Behe’s reply deals with his understanding of how gene duplication relates to his argument from IC, I will quote it here at length:  </p>

<blockquote><p>I have never stated, nor do I think, that gene duplication and diversification cannot happen by Darwinian mechanisms, or that “they play almost no role at all” in the unfolding of life. (As a matter of fact, I discussed several examples of that in my 2007 book <em>The Edge of Evolution</em>. That would be silly — why would anyone with knowledge of basic biochemical mechanisms deny that, say, the two gamma-globin coding regions on human chromosome 11 resulted from the duplication of a single gamma-globin gene and then the alteration of a single codon? What I don’t think can happen is that duplication/ divergence by Darwinian mechanisms can build new, complex interactive molecular machines or pathways. Assuming (since he is in fact critiquing them) Professor Coyne has been attentive to my arguments, one background assumption that he may have left unexpressed is that he thinks the newer duplicated genes discovered by Professor Long’s excellent work represent such complex entities, or parts of them. </p>

<p>There is no reason to think so. A gene can duplicate and diversify without building a new machine or network, or even changing function much. The above example of the two gamma-globin genes shows that duplication does not necessarily result in change in function. The examples of delta- and epsilon-globin, which, like gamma-globin, presumably also resulted from the duplication of an ancestral beta-like globin gene, show that sequence can diversify further, but function remain very similar. Even myoglobin, which shares rather little sequence homology with the other globins, has not diverged much in biochemical function. </p>

<p>In his recent work Professor Long discovered that many of the new genes were essential for the viability of the organism — without the gene product, the fruitflies would die before maturity. Perhaps Professor Coyne thinks that that means the genes necessarily are parts of complex systems, or at least do something fundamentally new. Again, however, there is no reason to think so. The notion of “essential” genes is at best ambiguous. We know of examples of proteins that surely appear necessary, but whose genes are dispensable. The classic example is myoglobin. It is also easy to conceive of a simple route to an “essential” duplicate gene that does little new. Suppose, for example, that some gene was duplicated. Although the duplication caused the organism to express more of the protein than was optimum, subsequent mutations in the promoter or protein sequence of one or both of the copies decreased the total activity of the protein to pre-duplication levels. Now, however, if one of the copies is deleted, there is not enough residual protein activity for the organism to survive. The new copy is now “essential”, although it does nothing that the original did not do. </p></blockquote>


<p>The main points of Behe’s reply can be summarized as follows:  </p>

<ol><li>Gene duplications and subsequent changes to the copies (diversification) can and do happen, but the results are nothing really “new”— no new molecular machines or pathways (nor parts of such pathways), nor much in the way of new functions. </li>

<li>Duplicated genes can become essential simply by “sharing” the original function, and then reducing their share to a minimum, perhaps through the amount of protein that each copy makes. Again, this is not anything really new, since the copy doesn’t do anything that the original didn’t do already. So, the finding that some gene copies are essential genes is not a threat to the IC argument.  </li> </ol>

<p>Note that Behe’s reply makes predictions that can be tested with further research. These predictions might be summarized in this way:  </p>

<ol><li><em>If IC is correct, duplicated genes will not be part of new, complex molecular pathways or machines.</em></li> 

<li><em>If IC is correct, duplicated genes that are both essential should “share” the original function.</em></li></ol> 


<h3>Testing IC with new research</h3>

<p>Behe’s reply to the Chen paper is of course hypothetical and speculative – as demonstrated by his own comment that “there is no reason to think” that the duplicated genes are components of new complex pathways or systems. Accordingly, the validity of Behe’s reply depends on its ability to hold up over time as more work is done. Of note, the functions of p24-2 and its parent gene Éclair have been studied intensively since 2010. These studies, as we shall see in the next post in this series, shed quite a bit of light on these questions. </p>
