Wilkinson identifies a number of themes found throughout the Bible that can help us understand the Creator God in a more complex and fulfilling way—as, in Wilkinson’s own words, “a Creator God who is worthy of worship, enjoyment, and trust.”

Understanding John Polkinghorne: Theology of Nature

John Polkinghorne’s interest in natural theology is important, but what really sets him apart from most others is that he combines it with an equally strong interest in theology of nature, which is not the same thing. Where natural theology involves, “metaquestions about the pattern and structure of the physical world,” theology of nature involves, “metaquestions about how its historical process is to be understood.” Rather than “looking to the physical world for hints of God’s existence,” we look “to God’s existence as an aid for understanding why things have developed in the physical world in the manner that they have.” (Belief in God in an Age of Science, p. 13)

On this front, Polkinghorne advances a strongly Christocentric theology of creation, stressing Jürgen Moltmann’s notion of The Crucified God . In the context of Polkinghorne’s theology of nature, the point is that the Creator is the crucified and resurrected second person of the Trinity. Since I devoted a column to this before, I won’t say more here, except to alert readers to the singular importance this particular idea has for him—especially when facing the problem of suffering. “The insight of the Crucified God lies at the very heart of my own Christian belief, indeed of the possibility of such belief in the face of the way the world is.” (Belief in God in an Age of Science, p. 44)

Situating John Polkinghorne: The Resurrection of Jesus

Many Christians today see science as posing dangerous threats to their faith, challenging their understanding of the Bible and undermining core tenets such as the bodily Resurrection of Jesus, the historical basis on which the Christian faith stands or falls. “Evolution” is often identified as the problem, but the real danger is unbridled naturalism. A commitment to naturalistic methods, known as “methodological naturalism,” (MN) has been an integral part of science and medicine since the ancient Greeks. Those methods have been highly successful at producing a coherent, often very convincing picture of nature and the history of nature.

Advocates of Intelligent Design and some other Christians reject MN, but many Christians who work in the sciences and related fields (such as engineering, medicine, or the history and philosophy science) support MN as a properly grounded and properly limited way of understanding reality. In their view, a robust Christian faith is consistent with a commitment to MN, provided that the limits of scientific inquiry are not simply equated with the limits of rationally grounded belief. Polkinghorne fits squarely in this category.

To understand more clearly where Polkinghorne lies on the larger landscape of science and religion, let’s consider his approach to the Resurrection. Many contemporary thinkers, including some theologians and clergy, believe that “science” has somehow made it impossible to believe in the Resurrection, the deity of Jesus, and even belief in the transcendent God of the Bible.

A prime example is John Shelby Spong, a retired Episcopalian bishop whose books have sold more than one million copies. Spong sees the bodily Resurrection as a figment of the disciples’ imaginations, a vestige of a theism that now we must throw away like a threadbare suit of clothes. For Spong, Christians today need to go "beyond theism" throwing out the baby of divine transcendence—the fundamental truth of monotheism—along with the bath water of the credulity and mythology of the pre-modern authors of the Bible and the ecumenical creeds. Spong’s message is that “Christianity must change or die,” and all in the name of “science.”

As Spong likes to say, his work is very controversial, and not just among rank-and-file Christians. Scholars have also railed against him. “I have been attacked in books from the religious right by such people as Alistair MacGrath [whose surname is actually spelled McGrath], N.T. Wright, and Luke Timothy Johnson,” he complains (Why Christianity Must Change or Die, p. xvi).

I understand (with much sadness) that we live in a highly polarized age. Nevertheless, it’s difficult for me to grant much credibility to an author who identifies McGrath, Wright, and Johnson as representatives of the “religious right.” Indeed, if anyone here is distorting the news it is Spong, not they. As the (late) great Catholic biblical scholar Raymond Brown once observed, “I do not think that a single NT [New Testament] author would recognize Spong’s Jesus as the figure being proclaimed or written about.” (Birth of the Messiah, note 321 on p. 704)

Isenheim Altarpiece, ca. 1515), Unterlinden Museum,
Colmar, France

Polkinghorne certainly understands science far more than Spong does, and his conclusions about the implications of science for Christian beliefs are markedly different. With respect to the Resurrection, he is basically on the same page with his friend Wright, whose profound book, The Resurrection of the Son of God, he cites with appreciation. Belief in the Resurrection is well supported by the evidence, and the Resurrection, itself, is “the pivot on which the claim of a unique and transcendent significance for Jesus must turn.” Considering authors like Spong (although he does not explicitly name him), he adds, “it would be a serious apologetic mistake if Christian theology thought that operating in the context of science should somehow discourage it from laying proper emphasis on the essential centrality of Christ’s Resurrection, however counterintuitive that belief may seem in the light of mundane expectation.” (Theology in the Context of Science, pp. 135-6)

Amen.

Looking Ahead

This is the Easter season, and I’ll return in a couple of weeks to begin examining Polkinghorne’s approach to the Resurrection more fully, using excerpts from the chapter on “Motivated Belief” from his recent book, Theology in the Context of Science.

To illustrate why the debate about origins isn’t simply a matter of science versus religion, imagine living in a culture where there is a similar debate about the weather. The Bible clearly teaches that God governs the weather. Many Bible passages proclaim that God causes rain and drought (see Deut. 11:14-17; 1 Kings 8:35-36; Job 5:10; 37:6; Jer. 14:22). Writers of Deuteronomy, the Psalms, and Jeremiah refer specifically to storehouses of rain and snow (see Deut. 28:12, 24; Ps. 135:7; Jer. 10:13).

What causes the rain? Most of us were taught that water evaporates from the ground level, rises to where the air is cooler, and condenses into water droplets that form clouds. We learned how cold fronts and warm fronts and low pressure systems bring rain. When we watch meteorologists on television, we hear that scientists now use sophisticated computer models to help them understand and predict the weather a few days in advance. Their ability to understand meteorology is especially important for farmers, airline pilots, military personnel, and coastal residents. Every year scientists develop increasingly accurate computer models of the weather.

Now imagine that debates arise about what should be taught in schools about the weather. Imagine that prominent scientists write popular books about meteorology that state, “From our scientific understanding of the causes of wind and rain, it is clear that no divine being controls the weather.” Imagine that a professional organization of science teachers writes a set of guidelines that state, “Students must learn that all weather phenomena follow from natural causes; weather is unguided and no divine action is involved.” Meanwhile, other people insist that these scientific explanations of rain and wind must be wrong because the Bible clearly teaches that God governs the weather. These people write books and give public speeches saying, “Atheists have invented their godless theories about evaporation and condensation. But we can prove that their so-called scientific theories are false and that the Bible is true.” They go to churches and teach, “If you believe what these scientists are saying about the causes of wind and rain, then you’ve abandoned belief in the Bible.” They petition school boards and courts to require that science classrooms also teach their “storehouses” theory of the weather as an alternate explanation to evaporation and condensation.

If you lived in a world with that sort of debate going on, would you be content to see it simply as a conflict between science and religion? Would you be willing to agree wholly with one side or the other?

Fortunately, we don’t have such debates about what causes the weather. The majority of Christians say that when it comes to the weather, both science and the Bible are correct. God governs the weather, usually through the scientifically understandable processes of evaporation and condensation. And the majority of atheists today would also agree that having a scientific explanation for the weather, by itself, neither proves nor disproves the existence of God. So there are no court battles about what science classrooms should teach about the weather. Debates about creation, evolution, and design have some similarities to the above example, but in many ways they are more difficult. The questions about how to interpret Scripture are more challenging, and these debates raise more theological issues. Still, a good place to start in making sense of these debates is to remember that more than two options exist; it is not simply a choice of science or faith.

Christians in Agreement

When Christians discuss creation, evolution, and design, it is easy to focus immediately on areas of controversy and disagreement. We think it is important to start by pointing out certain areas on which nearly all Christians agree. Christians generally agree about the fundamentals of God, God’s Word, and God’s world in the five areas.

God created, sustains, and governs this universe.

This truth is confirmed in the first line of the Apostles’ Creed, one of the ecumenical creeds of the church which many Christians recite every week: “I believe in God, the Father almighty, creator of heaven and earth.” Christians believe that God created all things from nothing, bringing them into being through his Word, his Son (John 1:1-3). God continually sustains the whole universe, governing all creatures according to his providential care.

The God who created this world also reveals himself to humanity.

God has revealed himself at various times and in multiple ways throughout history, including the written Scriptures and the Incarnation. As it says in the first verses of the book of Hebrews,

In the past God spoke to our ancestors through the prophets at many times and in various ways, but in these last days he has spoken to us by his Son, whom he appointed heir of all things, and through whom also he made the universe. The Son is the radiance of God’s glory and the exact representation of his being, sustaining all things by his powerful word. After he had provided purification for sins, he sat down at the right hand of the Majesty in heaven. (Hebrews 1:1-3, NIV)

The God who created this world is also our Redeemer.

We belong to God because he created us, but when humanity turned from God he bought us back. He redeemed us through the incarnation, life, suffering, death, and resurrection of Jesus Christ.

The Bible is authoritative and sufficient for salvation.

God inspired its human authors and ensured that the Bible truthfully teaches what he intends. The Holy Spirit testifies in our hearts that the Bible’s message is from God, not merely human writing. Christians accept the sufficiency of the Bible for establishing our core beliefs and practices; all that we need to know for salvation is taught there. God certainly can use various means— including the natural world—to teach us new things. But these new things should be compatible with, not contradictory to, what God teaches in Scripture.

God is sovereign over all realms of human endeavor and has given human beings special abilities and responsibilities. Theologian Cornelius Plantinga puts it this way:

God’s creation extends beyond the biophysical sphere to include the vast array of cultural possibilities that God folded into human nature. . . . God’s good creation includes not only earth and its creatures, but also an array of cultural gifts, such as marriage, family, art, language, commerce, and (even in an ideal world) government. The fall into sin has corrupted these gifts but hasn’t unlicensed them. The same goes for the cultural initiatives we discover in Genesis 4, that is, urban development, tent-making, musicianship, and metal-working. All of these unfold the built-in potential of God’s creation. All reflect the ingenuity of God’s human creatures—itself a superb example of likeness to God. —Cornelius Plantinga, Engaging God’s World, 2002.

Applying this idea to the natural sciences, we conclude that God has graciously given humans the ability and responsibility to study the natural world systematically. As with all human endeavors, we do it imperfectly. We must seek to do it as God’s imagebearers, in gratitude for God’s gifts.

Christians in Disagreement

Christians have always agreed about who created everything, but in the last few decades they have often disagreed about how God created everything. These disagreements are over two basic questions:

• As we study God’s Word, what is the best way to understand passages that talk about God’s acts of creation?
• As we study God’s world, what can we reliably conclude that it tells us about its history?

Some Christians describe themselves as young-earth creationists. They believe that the best interpretation of the book of Genesis is that the earth is only a few thousand years old and was shaped by a global flood. Young-earth creationists hold a range of views about how to interpret Scripture, the extent to which scientific data indicates a young universe, and the extent to which it indicates at least an appearance of long history.

Other Christians describe themselves as old-earth creationists. Some believe that in the best interpretation of Genesis 1, the events on each day actually describe several long epochs of scientific history. Others believe that the best interpretation of the book of Genesis does not imply anything about the age of the earth one way or the other and that drawing conclusions about the age of the earth from Scripture is reading into it something it was never intended to teach.

Some old-earth creationists describe themselves as evolutionary creationists. They believe that the best understanding of the scientific data—in conjunction with the best interpretation of Scripture—implies that God governed and used evolutionary processes in the unfolding of creation. Other old-earth creationists describe themselves as progressive creationists. They believe that science and Scripture both indicate that God used not only natural processes but also some miracles along the way, particularly in the history of life. Arguments for Intelligent Design are usually, though not always, used to support versions of progressive creation.

In the remainder of the book Origins, the Haarsmas expand on these topics, investigating different Christian positions in detail.  Stay tuned for more excerpts in future posts.  Next week, we’ll feature an excerpt on the reliability of historical science.

Despite this usage, most of us know that randomness has something to do with probability, and that it often implies a lack of conscious intentionality. But what do mathematicians and scientists mean when they say something is random? Can a random process lead to an ordered, even predictable outcome? Is there evidence that God makes use of random processes to fulfill his creative purposes?

These are big questions, and we won’t address them all today. But I think randomness is an important topic to cover for two reasons: 1) it is integral to many processes in biology (and math, physics, chemistry, etc.), and 2) it is commonly misunderstood to be incompatible with Christianity.

As I said above, most of us know that randomness has something to do with probability. If you pick a card “at random” from a shuffled deck, you have a small probability of drawing an ace (4 out of 52, or a 7.7% chance). If you flip a coin, you have an equal probability of getting heads or tails.

Randomness also seems to imply a lack of intentionality or purposefulness. After all, you might hope for an ace when you draw a card, but you can’t choose one on purpose. You might call heads when you flip a coin, but you can’t know beforehand what the outcome will be. Thus the outcome is indeterminate, but is it purposeless? Not necessarily. Indeterminacy simply means the result cannot be predicted from the outset.

It should be noted that indeterminacy does not imply that God does not have foreknowledge of future events. Christians ought not to be uncomfortable with the idea of God interacting with his creation through chance. We often describe a seemingly-random (i.e. unplanned by us) sequence of events as being “providential,” or planned by God.

In biology, it is very hard or impossible to calculate precise probabilities for most processes, so when we say a process is random, we typically mean it is extremely unpredictable. Eventually we will discuss randomness within biological evolution, but first we must consider some simpler processes, like the self-assembly of a virus.

Viruses are remarkably efficient entities. Coiled tightly within a protein-based shell is a small amount of DNA needed for self-replication. The shell, called a capsid, is made of many repeating protein subunits and is therefore highly symmetrical (see figure). Important biomedical insights have certainly been gleaned from structural studies of viruses, but viruses also teach us about the emergence of order from non-order.

The virus life cycle has four main steps: 1) enter a host cell, 2) hijack the cell’s replication and translation machinery to make many copies of itself, 3) assemble into many virus particles, and 4) exit the cell to invade another host.

When I first learned about this process, I found it very hard to believe it just “happens.” The idea that a bunch of molecules bumping into each other inside a crowded cell could spontaneously assembly into a fully-functional virus seemed a bit far-fetched. Many viral capsids have over 100 protein subunits that must interact with each other in just the right way, or it won’t work. Surely there must be something driving this process, right?

There is! Random motion. I had to see it to believe it. I distinctly remember sitting in class during my first year of graduate school when the professor demonstrated self-assembly of a virus using a 3D model as shown in the following video. In less than 30 seconds, you can watch a jumbled heap of proteins become a beautifully ordered structure.

As the narrator explains, sub-assemblies form and break apart en route to the most stable structure, the full capsid. As the sub-assemblies begin to form, further associations with free subunits become more favorable and as a result occur rapidly, while the final steps may take considerably longer. While the subunits in the model are rigid, in reality the proteins take on multiple conformations, allowing the capsid to “breathe.”

Amazing as it is, the system we just considered—one virus capsid in a jar—is pretty simple. One wonders how self-assembly can happen in a crowded cell, where there are countless other molecules diffusing around, potentially getting in the way. We can’t directly see how it happens in a cell, but we can reconstitute the process in a test tube using different combinations of constituent molecules.

Consider two viruses, where each protein subunit in one virus is the mirror image of the corresponding subunit in the other. Putting the two viruses together by hand would be pretty tricky, because the constituent parts look so similar. But random motion can do the job in short order:

From this model, we can see clearly, in real-time, how distinct complex structures can arise from their parts randomly interacting with one another. Many large viruses also use special scaffolding proteins to assist in the assembly process, and some even use their own genomes as a scaffold. In addition, two closely-related viruses that happen to infect the same cell can exchange parts to create a new virus. This is one way viruses can evolve quickly to evade the host’s immune system.

Here we have seen how viruses demonstrate a principle inherent in God’s world—that order can emerge out of chaos from random processes. In my next post, we will look at some other biological processes that make use of—rather, depend on—randomness. This will set the stage for us to see that such processes can not only assemble a structure within seconds or minutes, but also generate complex, information-bearing molecules over billions of years. Even though the freedom inherent in nature sometimes produces unintelligently-designed structures (like viruses, which can kill us), we see that God has made, and continues to oversee by his providence, a good creation that, at least in part, is capable of creating itself.

Next weekend, we’ll continue this series about randomness and God’s divine will. Up next: how God created the body to heal itself, and how can random mutations can be both harmful and benign.

“This is 2,300 year old wisdom from the Book of Ecclesiastes that seems to very concisely understand the water cycle. That water evaporates from the ocean, gets stored in the atmosphere via clouds, comes down as snow or rain, and when it comes down on the mountain it’s often stored there, as snow is gathered via groundwater, streams, and rivers, and then through the river, returns to the ocean, again. What a beautiful, complex, interdependent, wonderfully mysterious way of providing water, life to the land … But what does this beautiful system teach us, Father, Son and Holy Spirit, about who we are? What is your word, God, about this river, that runs through the center of where we live?”

In this sermon, Pastor Jon Van Sloten of New Hope Church in Calgary, Alberta, describes how he set out to learn where the water from the Bow River, near their home in the Rocky Mountains, actually comes from. He interviewed scientists who study hydrology and have learned a curious truth about how this particular river keeps a steady flow the full year round. This modulating geophysical “safeguard,” which allows the Rocky Mountains to hold water and let it out at a slow trickle rather than a deluge during the annual snowmelt, speaks to Van Sloten of God’s grace at work in the world—grace we can’t see with the naked eye, but is there all the same.

Grantees will benefit from in-person interaction through a series of summer workshops in 2013, 2014, and 2015. These meetings will not only foster a broader knowledge base, but will build a sustained network of scholars and church leaders, both young and seasoned, who are serious about addressing the concerns of the church about evolution. Also in 2015, in connection with the third summer workshop, BioLogos will host a large conference open to scientists, scholars, and church leaders from around the world.

ECF History

In January 2012, BioLogos was awarded a multi-million dollar grant from the John Templeton Foundation to fund the work of scholars and church leaders on evolution and Christian faith. In spring 2012 we worked hard to get the word out. You may have seen announcements on the BioLogos website, in our newsletters, on the Books & Culture, Leadership Journal, or First Things websites, on your professional society’s listserv, or perhaps on your friend’s blog.

The response was overwhelming: we received 225 letters of intent for a total request of $21 million—about seven times the amount we had to offer. We needed to invite the most promising applicants to submit a full proposal, but recognizing the projects with highest potential would require broad expertise. From the beginning, we envisioned that a panel of scientists, pastors, and scholars would oversee the application and review process as well as play key advisory roles throughout the project. A team of eight highly qualified individuals came on board in the early months of the project. They reviewed each proposal and together recommended that BioLogos invite 86 applicants to submit full applications.

The deadline for submissions was October 1, 2012. As in the previous round, the ECF panel evaluated each proposal. In addition, we asked 55 other experts to participate, so that each proposal received 3-4 scores. Criteria for the decision included significance of topic, project design, creativity and innovation, long-term impact potential, feasibility, and budget.

The panel then met together November 29-30, 2012, to make the final funding decisions. In the end, they recommended that BioLogos give 37 awards, ranging from $23,000 to $300,000. BioLogos staff notified applicants of their awards on December 14, 2013.

The Grantees

As part of our objective to create a network of scholars and leaders, we awarded grants to organizations across the U.S. and the world. Thirty of the 37 grantees are domestic; seven are international, hailing from Canada, France, Great Britain, Netherlands, and Spain.

Two-thirds of the accepted projects will be led by teams—some with three or more Project Leaders. We expect that the teamwork and time spent together at our summer workshops will be the start of a long-lasting network of people dedicated to helping the church think carefully about origins.

Applicants chose to apply under one of three program tracks: interdisciplinary scholarship (Track 1), intra-disciplinary scholarship (Track 2), and translational projects (Track 3). Track 1 projects focus on both the collaboration between individuals in different disciplines and the development of projects at the interface of different content areas. Track 2 projects focus on work done within a specific discipline. Track 3 focuses on projects that encourage Christians, especially those within more conservative traditions, to engage in meaningful and productive dialogue to reduce tensions between mainstream science and the Christian faith. The numbers of grantees in Tracks 1, 2, and 3 are 6, 8, and 23, respectively.

Many of the scholarly projects tackle questions about Adam and Eve, the Fall, human identity, and Original Sin—some of the most critical interpretive issues for evangelical theology.  Some examples: 

• Theologian Oliver Crisp of Fuller Seminary will take an analytic theology approach to ask to what extent a theological account of the origin of human sin depends upon the evolution of modern humans from one and only one ancestral pair—especially if that pair does not appear to correspond to what we would think of as modern human beings. 

• Pastor Michael Gulker and philosopher James Smith, leading a large team from The Colossian Forum, ask a related question: if humanity emerged from non-human primates—as genetic, biological, and archaeological evidence seems to suggest—then what are the implications for Christian theology’s traditional account of origins, including both the origin of humanity and the origin of sin? 

• Biologist Dennis Venema of Trinity Western University and New Testament scholar Scot McKnight of Northern Seminary will write a book on the evidence for evolution and population genetics, with informed theological reflection on how these issues interact with orthodox Christianity.

• Biologist David Wilcox of Eastern University will develop an updated model of human identity which reflects the complex recent scientific advances in genetics and paleoanthropology and yet is sensitive to theological concerns.  

These are just a few of the scholarly awards; check out the Grantees page for full descriptions of all Track 1 and Track 2 projects.

All projects have translational potential, but Track 3 projects are designed to meet the needs of a particular constituency within the evangelical church. These projects run the gamut from ethics to education to media production to ministry resources.  Some examples include:

• Theologian Lee Camp of Lipscomb University will produce “The Questions in Monkey Town,” an episode of Tokens, a live variety show that features musical performances, comedic sketches, brief interpretive monologues, and dialog with authors and scholars. The episode will be performed and filmed on the site of the famous Scopes Trial in Dayton, Tennessee.

• Chaplain Joshua Hayashi and Educator Diane Sweeney of the Punahou School in Hawaii will lead a team to produce multimedia curricula aimed at helping high school students connect with their biology curricula and, at the same time, deepen their Christian faith.

• Physics teacher and pastor Benoît Hébert of Science et Foi Chrétienne in France will lead an international, multi-denominational team of French speaking Evangelical scientists, pastors and church leaders to produce a large number of resources on evolutionary creation.

• Pastor Seung-Hwan Kim of Grace Truth Community Church, a Southern Baptist church in Cambridge, Massachusetts, will produce teaching and preaching materials about evolution for church leaders.

• President Gregory Wolfe and Director of Resource Development for IMAGE will gather artists and writers of faith whose work explores the dialogue between evolutionary science and faith practice, convening a conversation between them and scientists, theologians, and church leaders in private and public conferences.

Again, this is just a taste of the diversity of Track 3 projects. Read more about each project on the Grantees page. You can look forward to an incredible variety of resources coming out of the ECF program, many of which will be featured right here on the BioLogos Forum.

A common argument leveled against the theory of evolution is that scientists have not been able to produce the expected transitional fossils that show the change of one species into another. If evolution were true, wouldn’t there be instances of clear intermediary species, like, for example, a species that was half whale and half hippo to show the transition between those two? In this BioLogos podcast, Kelsey Luoma addresses this misconception about what a transitional fossil actually is. Rather than a mix between two related species, transitional fossils point back to the common ancestors that modern species share. The fact is that the number of transitional species is massive and it grows with each passing year. Given the rarity with which organisms are actually fossilized, the amazing thing is actually the completeness of the fossil record, not its incompleteness. The transitional species story strongly supports, and certainly does not disprove, evolutionary theory. ¹

Showing Christian schoolteachers that one can be a believer who embraces the Bible as God’s inspired Word and evolution as His creative process has always been a mission of BioLogy by the Sea, the accomplishment of which is never guaranteed. During the first few days, several participants expressed doubt that their faith could be compatible with evolutionary creation. However, as the week came to a close, some of those who had previously denied compatibility seemed to be much more considerate of the notion—if not fully accepting of the idea altogether. If you’ve ever doubted evolution yourself, then you know that such acceptance is no small feat. There are numerous theological and philosophical barriers that must be dealt with, and to think that this could occur in the span of just one week is pretty amazing. Then again, the program had some pretty amazing guest speakers and activities—the most significant of which occurred throughout the week: prayer and worship to the One we all serve, our Lord and Savior Jesus Christ.

While these times served to glorify God and nurture participants’ souls, the week was also filled with activities designed to nurture participants’ minds through the study of biblical passages and biological content. In addition to graduate level courses and accompanying labs in either biodiversity or developmental biology, participants went on field trips to the intertidal zone, the Natural History Museum of Los Angeles County, the La Brea Tar Pits, and the Gaslamp Quarter. Furthermore, presentations given by Dr. Gregg Davidson, professor of geology and geological engineering from the University of Mississippi, and Dr. Mary Schweitzer, paleontologist and associate professor of marine, earth and atmospheric sciences from North Carolina State University, offered key insights into their fields and demonstrated how the tenants of both are based on evidence rather than conjecture.

In short, this year’s BioLogy by the Sea offered another comprehensive look at what it means to be a Christian who accepts the conclusions of mainstream science—not at the expense of our faith in God or His Word, but in light of it. We can only hope that these teachers, who spent an entire week of their summer break with us, left with not only a greater sense of oneness as the body of Christ, but also found new ways to engage their students in matters of science and faith—another facet of the program’s mission. After all, the first step in protecting the next generation from the faith crisis that many seem to experience after they learn about evolution from a secular perspective is showing that it need not be an either-or situation. It’s also an important part of ensuring that Christian young people can rise to the forefront of global scientific research.

These facts persist in the face of educational guidelines in most states that mandate the teaching of evolution, court decisions that have declared the teaching of creationism as unconstitutional and having “no scientific merit or educational value as science [because it] is simply not science” (McLean v. Arkansas Board of Education, 1982), thousands of scientific papers and books that document evidence for evolution, direct observations of evolution, and countless endorsements of evolution (and rejections of creationism) by professional scientific organizations. Decades of costly science education reform have not reformed popular acceptance of evolution: most of the public continues to see religion and mainstream science as diametrically opposed, and when presented with that choice, most will choose the supernatural over science, even when it means rejecting the foundations of modern biology. Why?

Many factors – for example, the media and religion -- influence people’s beliefs about the evolution and creationism, as well as their acceptance of science. One of these influences is education. What are students taught about evolution and creationism?

Evolution and Creationism in High School Biology Courses

Students have widely variable introductions to evolution in their high school biology courses. Although most states have educational guidelines that mandate the teaching of evolution, only about 70% of students entering college report that their high school biology courses included evolution (in some form) and not creationism. Although educational guidelines provide important support for teachers wanting to teach evolution, these guidelines are irrelevant to many biology teachers and administrators.

Approximately 20% of students are taught neither creationism nor evolution in their high school biology courses (Moore, 2007). Another “cautious 60%” of biology teachers want to avoid controversy, and neither advocate evolution nor explicitly endorse nonscientific alternatives (Berkman and Plutzer, 2011). Even when teachers do teach evolution, they often cover the topic in a trivial or disparaging way (Bandoli, 2008, and references therein), thereby perpetuating a cycle of ignorance reinforced by popular opinion (Berkman and Plutzer, 2011). When these students arrive on college campuses, they are predisposed to remain skeptical of evolution, for their perceptions and prior knowledge strongly influence their learning. This is especially important for evolution, for many students view evolution as negative and undesirable (Brem, Ranney, and Schindel, 2003) and sense an “overlap of some ideas that the theory [of evolution] advocates with other social, epistemological, and religious beliefs” (Hakoyem and BouJaode, 2008).

The Creationists Down the Hall

Most Americans reject evolution, and most biologists have grown accustomed to headlines such as “Four in 10 Americans Believe in Strict Creationism” (Gallup, 2010) and “In U.S., 46% Hold Creationist View of Human Origins” (Gallup, 2012). However, most biologists are less familiar with the fact that creationism is thriving among undergraduate biology majors (Verhey, 2005; also see above), biology graduate students (Gregory and Ellis, 2009), and former students who have become biology teachers (Berkman, Pacheco, and Plutzer, 2008; Moore, 2007, and references therein).

Despite their training, many biology teachers are creationists. Indeed, fully one-sixth of biology teachers are young-Earth creationists (Berkman, Pacheco, and Plutzer, 2008), and a presentation of young-Earth creationism as legitimate science would presumably confuse students about the basic tenets of science in general, and of evolution in particular. Because teachers’ personal views about a subject affect their teaching of the subject (Carlesen, 1991; Grossman, 1989), and because teachers with strong religious convictions accept evolution less often than their less-religious peers (Trani, 2004), it is not surprising that many of today’s biology teachers explicitly teach creationism in their biology courses. Although few biology teachers in public schools teach creationism without mentioning evolution, 20-25% of today’s biology teachers teach evolution and creationism in their courses (Moore, 2007, and references therein). Although a handful of creationism-based biology teachers are confronted for their malpractice (e.g., Rodney LeVake; see Moore, 2004), most are tolerated — and sometimes even encouraged — to teach creationism, possibly because of pressure from the public and administrators to ignore evolution and/or teach creationism (Cavanagh, 2005, Verango and Toppo, 2005). As Don Aguillard, the lead plaintiff in Edwards v. Aguillard (1987) noted in 1999 (Moore, 1999), “Creationism is alive and well among biology teachers.”

When Biology Teachers Teach Creationism, What Do They Teach?

When biology teachers teach creationism, they usually present only a particular version of the Judeo-Christian creation story. Moreover, these stories are often presented as a scientific alternative to evolution (Moore, 2008), despite the fact that creation science has “no scientific or educational value as science [because it] is simply not science” (McLean v. Arkansas Board of Education, 1982). Relatively few biology teachers who teach creationism present it as religious idea, philosophical idea, or as part of a survey of several religions (Moore, 2008). They do not “teach the controversy,” in other words, but present the relationship between modern evolutionary biology and their faith as one of self-evident conflict, assuming (and teaching) that their version of creationism is the only true alternative.

Does It Matter When Biology Teachers Teach Creationism?

Yes—high school biology courses have a strong and lingering impact on students’ views of evolution and creationism (Moore and Cotner, 2009). Students who were taught creationism in high school know significantly less about evolution when they enter college than do students who were taught evolution in high school. Similarly, students who claimed that most of their knowledge of evolution came from non-school sources (e.g., the media, church) knew less about evolution than did students who claimed that their primary source of knowledge about evolution was their high school biology class (Moore, Cotner, and Bates, 2009).

Solving the Problem?

Several studies have claimed that additional evolution-related training will help improve the teaching of evolution in high schools. We are not nearly as optimistic. Although workshops and short-courses presumably help and encourage teachers willing to consider teaching evolution, focused instruction about evolution often does not affect students’ or teachers’ acceptance of evolution (Alters and Nelson, 2002; Chinsamy and Plaganyi, 2008). Moreover, these workshops will not reach creationism-based biology teachers who are dedicated to substituting their religious beliefs for science in their classes.

In our experience, these teachers rarely attend such workshops, even if they are paid to do so, and even then their acceptance of evolution is unaffected. After all, these teachers have access to and know the evidence for evolution – it’s widely available, including in the textbooks that they adopt and use in their classes – and they are not convinced by that evidence. We know of no evidence that the availability of such solely science-focused workshops, seminars, and other forms of evolution-related education will significantly affect what creationism-based biology teachers teach. Since the impediments to better teaching of evolution are primarily the philosophical and religious views of biology teachers, programs that do not address the more personal, “non-science” issues of science educators directly and effectively are likely to have little impact on what students learn in high-school biology classrooms. Instead, if further fact-based instruction in evolution is part of the answer, it is likely to be most effective with young children, who are developmentally primed to seek explanations for natural phenomena. However, evolution instruction is essentially absent prior to high-school biology; by high school, a student’s teleological demands have likely been met by supernatural explanations, creating a cycle of adults who know little about evolution and teach creationism-flavored biology.

Creationism has long been popular among biology teachers (Moore, 2007), and there is no evidence that improved state educational standards, proclamations by professional organizations, and decades of science education reform have made much difference. As John Scopes commented almost 50 years ago, “I don’t think the world changes very rapidly” (Anonymous, 1966).

Part of the BioLogos mission, then, is to show how all things hold together in Christ—to show how a Christian worldview integrates the knowledge we have of God through the Scriptures with the knowledge we have of God through the other areas in which he reveals himself as Creator and Redeemer. Our website contains a wealth of Christian scholarship in a wide range of fields—from biology, to cosmology, to mathematics, to Biblical studies, to history, to theology—all demonstrating that the best contemporary science is compatible with Biblical Christian faith. But today we introduce a new tool—the BioLogos Navigator—to make these posts more accessible, and to show how they inter-relate (see sidebar on the right).

Modeled on the astrolabes that early astronomers and sailors used to orient themselves under the heavens, our Navigator makes the cross of Christ the starting point by which we understand the cosmos. Each of the four arms of the cross represents one of the domains of knowledge and experience through which God reveals himself to the world: Scripture, the Church, Nature and Culture. These domains are not in opposition to each other, but are complementary and inter-related areas through which we can recognize God at work in the world. Linking these four domains is a network of specific topics relevant to the science and faith conversation. Their arrangement suggests how each relates to the four domains but also to teach other. Clicking on an individual topic tag highlights not only that topic, but other topics that are linked to it—sometimes in unexpected ways.

Clicking a topic tag a second time takes you to the Topic Landing page: a curated selection of the best resources on that subject from the BioLogos archives. (The image above shows the Christianity & Science—Then and Now Landing page, complete with Navigator and highlighted tags.) At the bottom of each page is a link to our Resource Finder, where you can investigate additional materials on that topic, as well. By exploring the relationships between the topics on the Navigator itself, and by delving deep into each topic via the resources presented on the landing pages, readers can focus on specific aspects of the harmony between science and Christian faith while also getting the wide view of God’s providential work in all things in the heavens and on the earth.

In the coming days and weeks, the BioLogos Navigator will be more fully integrated into the rest of the site, accessible directly from the Forum homepage and from the Resources dropdown list at the top of every page. We’ll also be including features that help place each blog post on the “knowledge map” defined by the domains and topic tags. Finally, the Topic Pages will also be periodically updated with the latest and best new materials in each topic. In the meantime, you can access the Navigator by clicking anywhere on the small image in the sidebar, above, and find a link to this post at the upper right corner of our homepage. So take some time to explore our site with this new tool, which we think will to help orient our readers in the science and faith conversation, while always pointing to Jesus, the Christ, through whom all things were made.

If a cadre of outspoken, strong atheists wrote a litmus test for scientists, that might very well be question #1.

"Scientists, if you're not an atheist, you're not doing science right," PZ Myers -- a well-known blogger, biology professor and atheist -- regularly preaches.

But if this is true, then as many as half of scientists are doing science wrong. A 2009 study from the Pew Research Center polled members of the American Association for the Advancement of Science (AAAS). Fifty-one percent of respondents reported a belief in a higher power. Does this mean that it's too late for science? Has religion already pillaged the minds of researchers worldwide? No, of course it hasn't.

"It seems to me that we as a society have lately been caught in this false dichotomy where it's either God as the guy with the beard on the cloud or nothing at all," neuroscientist David Eagleman told Discovery News.

Staunch atheists often falsely characterize followers of religion as being "all-in" with their beliefs, opining that they ascribe to the whole creationist, woo-y shebang. "Where's your evidence?" atheists mockingly question. "You can't prove that God exists!" they accuse (correctly). Yet, hypocritically, strict atheists are guilty of the exact same crime: belief without evidence.

"We know too little to commit to a position of strict atheism. [But] we know way too much to commit to any particular religious story," Eagleman said.

Just as it's a leap of faith for a religious person to assert that God incontrovertibly exists, it's an equally large leap for a strict atheist to declare, without question, that God does not exist. As Carl Sagan eloquently explained:

An atheist is someone who is certain that God does not exist, someone who has compelling evidence against the existence of God. I know of no such compelling evidence. Because God can be relegated to remote times and places and to ultimate causes, we would have to know a great deal more about the universe than we do now to be sure that no such God exists. To be certain of the existence of God and to be certain of the nonexistence of God seem to me to be the confident extremes in a subject so riddled with doubt and uncertainty as to inspire very little confidence indeed.

Absence of evidence is not evidence of absence. As this statement applies to science, so does it apply to religion. History is replete with signs that an all-powerful deity may not exist, but such substantiation is nowhere near tantamount to proof -- especially, as Albert Einstein said, in a universe as incomprehensibly vast as our own:

The human mind, no matter how highly trained, cannot grasp the universe. We are in the position of a little child, entering a huge library whose walls are covered to the ceiling with books in many different tongues. The child knows that someone must have written those books. It does not know who or how. It does not understand the languages in which they are written. The child notes a definite plan in the arrangement of the books, a mysterious order, which it does not comprehend, but only dimly suspects. That, it seems to me, is the attitude of the human mind, even the greatest and most cultured, toward God. We see a universe marvelously arranged, obeying certain laws, but we understand the laws only dimly.

Ultimately, the key is not to be swayed to one extreme or the other -- fundamentalist religion or strict atheism -- but to walk a reasoned middle path. Eagleman believes that path is "possibilianism," the concept of holding multiple beliefs or hypotheses whilst exploring new ideas.

"The goal is to avoid committing to any particular story," Eagleman told Discovery News, "whether that's religious fundamentalism or strict atheism. The goal of possibilianism is to retain the wonder that drives us all into science in the first place and to avoid acting as though we know the answers to things we can't possibly know at the moment."

Strict atheists do the world an incredible service by promoting the scientific method, skepticism, and critical thinking. But they do a disservice by campaigning against religion or touting -- as pure truth -- the non-existence of God, for those actions (especially the latter) are just as unscientific as a blind belief in all aspects of religion.

This summer, a worldwide poll showed that atheism is on the rise and religiosity is on the decline. It is my hope that these "New Atheists" and agnostics won't narrowly focus on denigrating religion, but will instead focus on encouraging open-mindedness and discouraging fundamentalism.

That would surely make the world a more enlightened place.

(4) Methodological naturalism (MN) is not a legitimate principle to employ, when it comes to understanding the origin(s) of objects exemplifying “specified complexity.” MN arbitrarily restricts science to finding only “natural” causes, when “intelligent” causes may actually be operative in some instances. Furthermore, MN is tantamount to “methodological atheism,” and to insist on it in each and every case leads to ontological (or metaphysical) naturalism—another word for atheism.

This might be the single most important tenet of ID, even more important than (2), that the universe itself, and some of the objects that compose it (both living and nonliving), exhibit abundant evidence of having been “designed.” This is also probably the most controversial of the tenets, and in order to see why, we need to understand the meaning of methodological naturalism.

A few years ago, when historian Ronald Numbers tried to determine who coined the term (“Science Without God,” p. 320 note 2), he tentatively credited it to philosopher Paul de Vries of Wheaton College, who had used it in a paper he delivered at an academic conference in 1983 and then published three years later (see the Print References). His article is not available on the internet, but one can get a good sense of his idea and what motivated him from a commentary written by Southern Baptist theologian Hal Poe and his former student Chelsea Mytyk. De Vries stressed that MN is simply a disciplinary method that makes no claims about God’s existence, while “metaphysical naturalism” is a wider philosophical position that denies a transcendent God. Many TEs endorse precisely this distinction, whereas I cannot name any ID author who likes it. This may indeed be the single most fundamental difference between TE and ID.

It’s worth noting in passing, however, that de Vries was not actually the first person to speak about “methodological naturalism.” Several authors since the early twentieth century have used the term, though not always with the same precise meaning. Perhaps the most significant of these was theologian Edgar Brightman, a student of Borden Parker Bowne, whose philosophy of religious “personalism” influenced some important modernist Protestants from the 1920s. Brightman discussed a form of MN on pp. 213-14 of A Philosophy of Religion (1940), a work that influenced Martin Luther King, Jr.

For our purposes, though, I’ll use the definition from an article I wrote with philosopher Robin Collins (who was at the time a Fellow of The Discovery Institute). We defined MN as “the belief that science should explain phenomena only in terms of entities and properties that fall within the category of the natural, such as by natural laws acting either through known causes or by chance.” This is to be distinguished from “ontological naturalism” (or “scientific naturalism”), “the claim that nature is all that there is and hence that there is no supernatural order above nature,” plus “the claim that all objects, processes, truths, and facts about nature fall within the scope of the scientific method.”

Ever since the Pre-Socratic philosophers, scientists and physicians have insisted on giving “natural” explanations for “natural” phenomena, leaving miracles explicitly out of science. Christians have done likewise, going back at least to the high Middle Ages if not earlier. It would be easy to cite many “big name” examples, including Johannes Kepler and Robert Boyle. Readers who want to know more about this are invited to consult the essays by Numbers and Davis & Collins in the appended list of references. I’ve also seen several more examples in an excellent essay on the topic of God and MN by a Christian philosopher (whose name does not appear anywhere in this column), but it would be inappropriate for me to cite it before it’s been published.

This doesn’t mean that no scientists believe in miracles; quite the contrary—probably tens of thousands of American scientists (including many TEs) believe that miracles are possible and that some have happened. They simply don’t believe that miracles can be part of scientific explanations. Even proponents of the YEC view don’t invoke miracles in what they call “operation science” (or “experimental science” or “ordinary science”), reserving them only for “origin science” (or “historical science”). (See my discussion of this distinction in "Galileo and the Garden, Part 2".)

According to mainstream science (including most advocates of TE), scientific explanations are “natural” explanations; they can’t invoke the “supernatural,” i.e., God or the gods or miracles. To some extent, I think that ID cannot entirely escape this problem, as I explained in my previous column. However, another important distinction poses “natural” causes vis-à-vis “intelligent” causes, which are not necessarily “supernatural.” We all know, for example, that skyscrapers don’t come about “naturally,” but they require “intelligent” causes to design them. The real question is whether any “natural” objects—such as galaxies, rocks, trees, or people—also require “intelligent” causes to design them and, if so, whether such causes should be part of any scientific explanations of those objects. Dembski’s idea of “specified complexity” and Behe’s idea of “irreducible complexity” come into play just at this point. ID proponents believe that the scientific toolbox needs to include “design,” an explanatory tool that includes rather than excludes intelligent causation as part of the explanation for how certain things came into existence. Their opponents think the scientific toolbox is large enough as is, without adding “design” to the set.

This is a difference of opinion about the nature of science itself. As a philosophical argument, it’s not likely to be settled by appeals to bacterial appendages or the Cambrian explosion or pseudogenes in humans and chimps. Prior to the Scientific Revolution, “design” was generally accepted or assumed within science. During the Scientific Revolution, a split began to take place, as some scientists argued that invoking design had no scientific benefit (design might explain why we have something, but now how it works), even though almost all of the early scientists were Christians who fully accepted the reality of a God who had, in fact, designed all of nature. By around the middle of the 19th century—coinciding with Darwin, who sought to make biology look more like physics and astronomy, disciplines in which unbroken “natural laws” already held sway—design largely disappeared from scientific discourse.

NOTE: Contrary to what is sometimes said, natural theology did not disappear after Darwin. Scientists themselves (not just philosophers and theologians) continued to contribute to it, right down to our own day (Polkinghorne is an obvious example). It’s simply that one no longer expects to find “God” or “design” (in the transcendent sense that is clearly meant by ID proponents) in scientific literature.

There are probably several reasons for this development, but I’m not confident that I understand them well enough to talk about it here. For our purposes, it’s enough just to state that ID proponents want to reverse this history. As William Dembski has written, “The scientific picture of the world championed since the Enlightenment is not just wrong but massively wrong.” What is the root problem? “Naturalism is the intellectual pathology of our age. It artificially constricts the life of the mind and shuts down inquiry into the transcendent.” ID, on the other hand, is “the only alternative” to naturalistic evolution, and in order for it to succeed we must “dump methodological naturalism. We need to realize that methodological naturalism is the functional equivalent of a full-blown metaphysical naturalism. Metaphysical naturalism asserts that nature is self-sufficient. Methodological naturalism asks us for the sake of science to pretend that nature is self-sufficient.” (Intelligent Design, pp. 224, 120 and 119, his italics)

Advocates of ID challenge both forms of naturalism at every opportunity. In their view, MN is really nothing but “methodological atheism,” another term that rose to prominence in the debate about ID but also originated earlier. (It might have been introduced by sociologist Peter Berger in the late 1960s.) According to Phillip Johnson, the founder of the ID movement, “Methodological atheism and [the world view of] naturalism are identical.” (Reason in the Balance, note on p. 99, his italics) Thus, some ID thinkers—especially the evangelical philosophers Alvin Plantinga, Steven Meyer, and J. P. Moreland—have made the case for rejecting MN in favor of what Moreland calls “theistic science” or Plantinga calls “Augustinian science”. Another evangelical philosopher, Robert O’Connor, offers a vigorous defense of MN. Many other Christian scholars have weighed in on this; some examples are among the links assembled here. (In passing, let me note that most of these articles were published in the ASA’s journal. This belies the charge sometimes made by ID advocates that the ASA is unfriendly to their position; I think this simply reflects frustration that more ASA members have not found ID sufficiently persuasive.)

So—is MN in fact equivalent to atheism? That’s the rock bottom question here, and there simply is no consensus—neither among Christians nor even among atheists, for that matter. I defended it myself several years ago in a brief exchange with Phillip Johnson, who had written a letter in reply to my review of three ID books, including one of his, which ran as a cover story for Reports of the National Center for Science Education.

Let me give the final word to Loren Wilkinson of Regent College, whose short article, “Does Methodological Naturalism lead to Metaphysical Naturalism?” should not be missed:

“What is at issue, therefore, is not the fact of an elusive and ultimately unattainable scientific description [a complete scientific description of the origin and development of living things], but rather whether the ideal of such a description is incompatible with the loving, personal, creator God revealed to us in Scripture and in Jesus Christ. Yet the ideal that complete understanding of a process excludes God from the picture contradicts our normal Christian practice. We regularly, for example, thank God for our food: rightly recognizing it as God’s provision. Yet we could, if we took the effort, trace the corn or tomato back through many manmade and ‘natural’ processes to its source. The practice of the ‘methodological atheism’ of going regularly to the store (or the garden) to obtain such food does not necessarily produce ‘metaphysical atheism’ in the eater, who still ought to thank God for his provision.” (Darwinism Defeated? pp. 169-70)

It’s your turn now to weigh in. I hope your comments will reveal some familiarity with the books and articles I’ve mentioned, but of course there are so many others that I failed to mention—in which case I hope you will introduce all of us to them. HAPPY THANKSGIVING to my American readers, and best wishes to all.

Looking Ahead

I’ll be back in about two weeks, to discuss some conclusions we might draw about ID.

The first video, “10 Questions with Katherine Hayhoe”, introduces the scientist in a brief and lighthearted interview. Hayhoe is presented with 10 questions concerning her personal life and beliefs. When asked, she explains that one thing people should know about Christianity is that having a relationship with the God of the universe is one of the most incredible experiences that a person can have. As the video unfolds, the viewer quickly begins to realize that, despite her unique profession of two seemingly incompatible beliefs, Hayhoe is a remarkably sane and “normal” individual. Her role model, she explains, is her father-- the person who first introduced her to science and showed her that it could be “really cool”. On a more serious note, the scientist admits that being both a scientist and a Christian can be difficult. The most frustrating thing about her position, she says, is the amount of disinformation which is targeted at her very own Christian community.

In the second video, “Climate Change Evangelist”, Katharine Hayhoe delves into deeper discussion of the perceived conflict between climate change and Christian faith. She explains that admitting her identity as a Christian scientist can be uncomfortable. Since evangelicals are the targets of much disinformation concerning science in general -- and specifically the science surrounding climate change -- many people in the church have a misguided view of the subject and do not look kindly at her career choice. One woman encountered by Hayhoe at a church in Texas, for example, believed that global warming was a lie taught in schools to mislead her children. In an effort to realign misguided views like these, Katharine Hayhoe and her husband wrote a book addressing the deep-rooted emotions often associated with climate change. People fear that addressing the climate issue will bring forth changes in the economy and uproot their way of life. However, Hayhoe encourages her viewers to act out of love, as the Bible calls us to do, rather than out of fear. Acting out of love inspires us to consider the poor and disadvantaged people around the globe when we respond to the reality of a changing climate.

In the final segment of this three part video montage, Hayhoe addresses the question of what climate change means. Specifically, she is concerned about how global warming affects people on a personal level. While global warming generally brings to mind melting ice caps and polar bears, its implications are far more widespread, affecting the lives of everyone around the world- from cotton farmers in Texas to public health workers in Chicago. If nothing is done to change current emission levels, the number of days per year which exceed 100 degrees Fahrenheit, for example, will begin to increase dramatically, and if emissions are increased, many areas will even develop extreme conditions like those seen currently in Death Valley. Hayhoe’s goal is to demonstrate clearly that the only way to preserve the world for future generations is to significantly reduce dependence on inefficient means of getting energy and instead transition to cleaner renewable energy sources.

There are more things in heaven and earth, Horatio, than are dreamt of in your philosophy.

—Hamlet Act 1, Scene 5

We live in a world driven by the gods of economics, technology and science. Particularly in a time of economic austerity, it is tempting to see the arts or humanities as an optional “extra”—a happy by-product of those true engines of society when they are running smoothly. But in this article we will look at how a biblically informed worldview might turn this perspective on its head, and what the humanities might have to tell us about the present contours of the science and faith conversation.

In his iconic 1959 Rede lecture, “The Two Cultures,” CP Snow noted the dysfunctional relationship between science and the humanities, arguing that the situation is principally the result of our educational system in the West. Ken Arnold, from the medicine and arts focused Wellcome Collection in London, believes that the split continues today, but with the further extension that

In emerging countries . . . amongst the middle classes there is a strong pressure to join the ranks of doctors and scientists and engineers because they see that as the place where future economies are growing. . . . In some ways you could almost begin to feel sorry for the arts and the humanities because they seem to be worth less than the sciences.¹

Is Protestant Christianity also peculiarly prone to such thinking? A skepticism of art in religious spaces as a result of iconoclasm and the reformation, combined with a proud history of the protestant work ethic, economic success, and a profound influence on the history of science, might lead Protestants to be more inclined towards the sciences and technology than to the arts. However, there are more corrosive reasons that science has usurped the humanities in our culture than merely educational or theological bias.

In the early 20th century, logical positivists regarded the humanities as expressions merely of our inner states and desires, but having nothing to do with objective reality. Such imperialistic claims to knowledge denied that other knowledge claims referred to any true reality, and were therefore not really forms of knowledge at all. Bertrand Russell writes,

But if there is a world which is not physical, or not in space-time, it may have a structure which we can never hope to express or to know … Perhaps that is why we know so much physics and so little of anything else.²

Christian scientists are of course very sensitive to this, and work hard to explain that science cannot answer questions of ultimate meaning or the existence of God, which are beyond the scope of science. Often, this line of thinking can be narrow in focus, delineating the limits of the science, and naming those assumptions made by science that cannot be justified empirically. Such arguments can be very fruitful within this narrow context, but we should not be led into thinking that our true perception of reality is limited to such analytic and evidential approaches. There are fields of inquiry that science isn’t able to explain (such as metaphysical judgments, ethics, and beauty), and even our confidence in mathematics— upon which so much of science itself is based—rests upon assumptions that cannot be experimentally demonstrated.

The human condition

Mathematics and the sciences do seem to provide tools by which we are able to perceive the external world and its regularities. However, the arts and humanities, too, are a way of understanding reality, and they tell us less about external reality than the internal human condition. The problem is that the ‘human condition’ seems to have been relegated by many to the realm of mere desire and subjective feeling and, therefore, not reality.

The modernist account of science is that, through our reason, we are somehow able to get outside of nature and describe it objectively. The biblical account, though, has human beings as part of the created order, and so embedded in nature—made from the dust of the earth. Given that, human thought life is also part of the natural world, even despite the fact that it is not best described by the sciences.

The works of Shakespeare, for instance, are part of the created order, as are the poems of Wordsworth, the sculptures of Michaelangelo, and the music of Bach, not to mention children’s nursery rhymes, home decoration, and humming tunes whilst waiting for the bus. As C. S. Lewis wrote, "This is not panache, it is our nature." ³

A little reflection on life reveals something very strange going on here. Somehow, the mythic ‘war’ between science and religion has become the dominant battleground for defending the Christian faith, and competing explanations of the material world are used as apologetic weapons. But the reality is that science plays a peripheral role in our experience of life, not least our life as Christians. Of course that is not to deny the enormous impact of science on the material conditions of our lives, or the prevalence of the products of science. Instead, it is to observe that science plays a facilitatatory role, enabling us to carry out the real core business of our lives, which does not revolve around science. Cars, trains and airplanes are modes of transport to take us to work, or to see family, or go on holiday. Social media provide another way of being in relationship with people. Health services are not an end in themselves, but aim to make people well, so that they can get on with their lives. Why then, when life is not about science, does science dominate our way of thinking about life?

In focusing so much energy on opposing positivism are we not being inadvertently drawn into a positivist way of thinking, that science and material explanations of things are, indeed, our basic reality, what is ultimately true?

A biblical model

“We feel,” wrote the philosopher Ludwig Wittgenstein, “that even when all possible scientific questions have been answered, the problems of life remain completely untouched.” ⁴ Likewise, philosopher Susanne Langer questions any philosophy which claims to be able to explain everything:

Philosophers in every age have attempted to give an account of as much experience as they could. Some have indeed pretended that what they could not explain did not exist; but all the great philosophers have allowed for more than they could explain, and have, therefore, signed beforehand, if not dated, the death-warrant of their philosophies.⁵

Fortunately, the Bible preserves us from total positivist oblivion. There are a great many types of literature represented in the Bible, with the notable exception of scientific writing. If we long to be able to express our deepest emotions, we have the psalms; if we are looking for wise advice, we have the proverbs; if philosophical reflection, Ecclesiastes. There is poetry, song, history, biography, but there is no science. In addition, the Bible refers to the use of the visual arts in, for example, the designs of the tabernacle and temple. The Bible does seem to think the arts and humanities are fundamental for human life, but it doesn’t seem to think that what we think the physical world is constructed of matters much at all.

Do we sometimes read the Bible more like a science textbook than a novel or a poem? Most will agree that each type of literature needs to be read in its own way, but lip-service to that idea notwithstanding, recent arguments prove that it is still possible to read a poem with a scientific mentality—looking out for the ‘facts.’ Is that because we have too high a view of science, or because we have too low a view of the humanities? To say something is poetic is not to declare it ultimately untrue, futile and meaningless—it is to say it is more profound and meaningful and true than many other modes of expression.

According to Langer, part of the problem is the priority that has been accorded to discursive language as the only valid way we have of representing reality to each other. She observes that a study of symbolism shows us that this is actually only one way humans use to abstract from reality, and in fact, the situation even with discursive language isn’t as simple as has been made out. She notes that our sensory organs mediate our perceptions of the world and are already on the job— formulating, framing the world to us—before our cognitive apparatus gets to work. It must be so, or we would not be able to evaluate the importance of the vast array of sensory data we receive and reality would appear as a blur.

A linguistic symbol carries a concept we associate with it, which in turn denotes a reality. In language there is a commonly agreed definition for each word we use, thus enabling communication. But each person also has associations unique to him or her which color any particular concept. Though such personal associations with words are present all at once, they can only be expressed and communicated one at a time, because language is also sequential.

A picture also acts symbolically, though in a different way. Even something as ‘realistic’ as a photograph is likewise a representation of reality and not the reality itself. It also carries with it layers of meaning which reflect the subjective intentions of the person who took the photograph, and opens up for interpretations and associations of the person ‘reading’ the picture. A picture, though, is not sequential. All the information comes at once, and individual blotches of color carry no significance on their own, but only as part of the whole.

No amount of words could ever describe a picture in full. The number of blotches of color and their relations to each other are vast in their complexity, and one could never read words quickly enough to carry the meaning a picture brings in an instant, even if it warrants a far longer period of contemplation. Indeed, though we are only speaking here of visual perception, the same is true of our other sensory inputs, too: they all carry knowledge in quite distinct and profound ways, whilst we, in line with the Greeks, have tended to give sight a special place as the most ‘objective’ of our senses.

As we dig down into empirical science and explore the mechanisms by which sights and sounds and textures are transmitted and processed by the brain, we discover that the meaning of the sense-data which we perceive and which we attempt to describe is likewise profoundly limited by the use of words—much less mathematics—and that our science, as such, represents a tiny fraction of reality.

To suggest, then, that science is the only true way of representing reality—as positivism has done—or to exclude the humanities from our world, leaves us without a proper or even adequate means of expressing the significance we attach to even the most mundane day-to-day activities. Science is very good at describing the regularities of the physical world, but the experience of being human is no less part of the real natural world than are the structure of proteins or the movement of planets, and science does not have the appropriate tools to explore our inner worlds.

Nowadays it seems that Christian cultural life has also too-often failed to fully acknowledge other ways of representing reality than materialist science—ironic because this state of affairs is so at odds with the Bible’s model of using the arts and humanities to profoundly explore the human condition. Perhaps it is time to recover that side of the biblical witness, and remind ourselves that there are more ways of representing the world to each other than positivism has ever dreamt.

Science and Technology are powerful forces in our modern world. Innovations in transportation, communications, agriculture, and medicine have dramatically improved the quality of human life. On the other hand, science and technology have also made it possible to destroy life on an unprecedented scale through instruments of modern warfare. It’s no wonder then that science evokes a wide range of emotions—from praise and hope to fear and distrust. In addition to a wide array of applied technologies, science also has unique explanatory power: it has revealed the immense age of the universe, the history and development of life, and the delicate balance of our environment. Science inspires us and challenges us, and like it or not, it continues to shape our lifestyles and self-understanding.

Given the diverse attitudes towards science in our country, it is important that we ask the question, “What exactly is science?” Does it give us absolutely certain knowledge? Is science truly objective and value-free? Does it eliminate purpose from the universe? Are there any limits to science?

This essay seeks answers to these questions. We will investigate them first by formulating workable definitions about what science is. Here in this post, we will focus on the philosophical and ethical foundations of science. In the next post, we will examine the goals and limits of science. In doing so, we will find that science is not a rigid, impersonal assemblage of facts, but a dynamic and distinctly human enterprise.

Defining Science

Mariano Artigas

What is science? Many authors have labored over this question, but the Spanish physicist and philosopher Mariano Artigas has offered a particularly insightful three-pronged definition:¹

1. Science is a goal-directed activity towards the knowledge and control of nature

As a goal-directed activity, science itself has purpose—it strives towards a more complete understanding of nature and the ability to modify it to serve human needs. These goals are understood to be valuable and worth the painstaking efforts necessary to achieve them. In these respects, science has values at its very core.

2. Science is a well-defined method

Another essential component of science is its method. Both Artigas and physicist Ian Hutchinson maintain that the scientific method defines science itself. Hutchinson singles out two particular characteristics that distinguish it from other forms of intellectual inquiry.² First, science relies upon experimental or natural evidence. Ideally, this evidence should be reproducible and thus subject to verification by other researchers. (Note: in some fields such as astronomy where one cannot actually reproduce events that take place many light-years away, one can make numerous observations as a basis of comparison. In disciplines such as the life sciences, biologists can rely on a multiplicity of specimens to approximate the need for reproducibility.)

Second, besides requiring a particular kind of evidence, the scientific method also demands certain types of explanations. They should be mathematical, mechanical, measurable, or quantifiable in some way. For example, one can take measurements of mass, number, length, time, velocity, pressure, volume, or many other discrete units. The goal is to create unambiguous results that are capable of creating consensus among other researchers, and understandable by anyone else who carefully investigates the topic.

3. Science is a body of knowledge

With these three dimensions of science firmly in mind, we have the basis for distinguishing science from non-science.³

Philosophical Foundations of Science

Despite its day-to-day reliance on empirical and measurable data, science rests on certain assumptions about knowledge itself that cannot be empirically proven. These basic premises are what allow us to ask scientific questions in the first place. While the lack of complete certainty is perceived by critics as a weakness, the dynamic nature of science is actually a great strength⁴— since scientific presuppositions are not set in stone, new discoveries produce feedback that enables us to reassess, and if necessary, modify our assumptions.⁵ Furthermore, our understanding of natural phenomena can improve dramatically over time provided that we first accept that “understanding” is possible in principle. With that in mind, let’s investigate some of the implicit premises that undergird the scientific enterprise and speak to the knowability of the world.⁶

Realism

Setting aside various nuances, realism basically maintains that there is a world that exists outside our minds. While this may seem self-evident, it is exceeding difficult, if not impossible, to demonstrate. Everything that we have ever experienced is mediated through our minds, and while we can imagine that an external world is stimulating our senses, the fact remains that we are still thinking about it. Plato and Descartes have famously wondered whether our lives are just a continuous dream, and in our own culture, the movie Inception explored this very same question. In a related way, the movie The Matrix invited us to consider whether our “reality” was just a computer simulation designed to placate us.

Philosophers have debated this topic ad nauseum, but scientists, in order to do their work, must suppose that there actually is an external world—otherwise, they would only be chasing dreams and illusions. The challenge of science is to figure out what the universe contains and how it works, not whether it exists at all.

Nature exhibits order and regularities

Science relies on the premise that there is some underlying order the universe that we can discover and understand. If nature were to totally reshuffle every day, none of the experiments we conducted yesterday would be reliable today, and there would be little basis for making any judgments about past or future events. Therefore, scientists depend on some degree of regularity within the universe in order to carry out their goals—namely the search for consistent patterns, structure, and organization of the physical world.

At the same time, science does not have a particular commitment to exactly what kind of order exists. Thus this presupposition is actually a flexible, accommodating principle that adapts to ongoing empirical research. Lest we think that modern discoveries have marred our conception of an ordered universe, even chaos theory and Heisenberg’s uncertainty principle have given rise to a better understanding about how nature is organized.⁷

Causality

Another distinguishing characteristic of modern science is the premise that every event is caused by another event; things don’t simply happen for no reason at all.⁸ When investigating various aspects of the natural world, scientists search for natural causes and natural explanations of those phenomena.⁹ Though this approach may seem unnecessarily constrained, it has had great success in accounting for previously mysterious terrestrial events like lightning, earthquakes, and volcanic eruptions, as well as celestial phenomena like comets, eclipses, and supernovae. On the human level, scientific research led to the development of germ theory, which has led to effective treatments for numerous diseases that used to be deadly. These are compelling practical reasons to adopt a scientific approach to natural phenomena, rather than being resigned to fate or purely supernatural interpretations of our world.

Natural laws regulate the universe

If you accept the three basic premises that there is a world external to your senses, that nature exhibits consistent and unvarying order, and that causality is universal, it follows that one can formulate natural laws that effectively describe and predict many phenomena that we encounter. In fact, describing the behavior of matter through mathematics and statistics has been enormously successful at the small scale of physics and chemistry, and computational approaches hold great promise in many fields of biology. Natural laws also help explain events on the largest scales of astronomy and cosmology.

On the other hand, human activities continue to vex us. It is notoriously difficult to predict political developments, economic fluctuations, and social movements. Some people think that this is due to fundamental uncertainties and vicissitudes of human behavior. Others think that it is “just a matter of time” before scientists uncover the laws that dictate our individual and collective decisions.

Are naturals laws completely universal in time and space, absolutely certain and inviolable? Not necessarily-- since empirical science only makes measurements at particular times and places, science itself cannot demonstrate that natural laws invariably apply to every event in the universe. Uncertainty is a central feature of the human condition, and not even science can eliminate it completely.

It should now be evident that science does not proceed from completely provable foundations. However, its fundamental principles are not arbitrary or dogmatic. The practice of science itself enables us to revisit and modify our initial premises. As Mariano Aritgas puts it, “Scientific progress provides feedback on its presuppositions—it retrojustifies, enriches, and refines them.” Science may not give us the complete certainty that many humans seek, but it does provide us with profound and remarkably reliable insights into the physical world we inhabit.

Ethical foundations

A publication of the National Academy of Sciences

We have just examined how science is grounded in a number of philosophical premises without which empirical research cannot proceed. But given how often we hear that science is purely objective and impartial, it may be surprising to learn that science also contains ethical premises. In fact, certain human values are intrinsic to the entire scientific enterprise. Research communities collectively embrace intellectual freedom, the right of dissent, cooperation, accurate communication of results, and personal responsibility for one’s claims.¹⁰ When individual practitioners or institutions circumvent these values, great damage can occur not only to the progress of knowledge, but in certain fields like biomedicine, they can endanger human life.¹¹

Science is not an activity carried out by uncaring automatons. It is a distinctly human endeavor conducted by those who believe that it is better to know than be deceived and that it is better to thrive than to suffer. Thus, to call science a strictly value-free and objective enterprise is a misnomer. Instead, it promotes distinct human values: the longing to understand the world that surrounds us, and the desire to improve and perpetuate human society.^{12, 13}

These approaches are not inferior to natural science; in fact, they can explore places that science cannot reach.

As we discussed yesterday, the most dramatic innovation yet observed in the E. coli Long Term Evolution Experiment (LTEE) was the ability, acquired by one of the twelve cultures, to use citrate as a carbon source under aerobic conditions. When we last discussed the LTEE in 2011, we noted what was known then about the mutations that eventually combined to produce the Cit+ trait:

Tracking down the nature of this dramatic change led to some interesting findings. The ability to use citrate as a food source did not arise in a single step, but rather as a series of steps, some of which are separated by thousands of generations:

1. The first step is a mutation that arose at around generation 20,000. This mutation on its own does not allow the bacteria to use citrate, but without this mutation in place, later generations cannot evolve the ability to use citrate. Lenski and colleagues were careful to determine that this mutation is not simply a mutation that increases the background mutation rate. In other words, a portion of what later becomes “specified information for using citrate” arises thousands of generations before citrate is ever used.
2. The earliest mutants that can use citrate as a food source do so very, very poorly – once they use up the available glucose, they take a long time to switch over to using citrate. These “early adopters” are a tiny fraction of the overall population. The “specified information for using citrate” at this stage is pretty poor.
3. Once the (poor) ability to use citrate shows up, other mutations arise that greatly improve this new ability. Soon, bacteria that use citrate dominate the population. The “specified information for using citrate” has now been honed by further mutation and natural selection.
4. Despite the “takeover”, a fraction of the population unable to use citrate persists as a minority. These cells eke out a living by being “glucose specialists” – they are better at using up glucose rapidly and then going into stasis before the slightly slower citrate-eaters catch up. So, new “specified information to get the glucose quickly before those pesky citrate-eaters do” allows these bacteria to survive. As such, the two lineages in this population have partitioned the available resources and now occupy two different ecological niches in the same environment. As such, they are well on their way to becoming different bacterial species.

As such, we noted three distinct steps observed by the Lenski group: steps they call potentiation, actualization, and refinement. Potentiation mutations do not themselves result in the ability to use citrate under aerobic conditions, but they are necessary for it to appear later. Actualization is the mutation that first brings about the Cit+ trait, though, as we noted, this step produced only a very weak Cit+ effect. This nascent ability, however, then undergoes refinement through additional mutations and selection to give the final, robust Cit+ trait observed in the culture.

While some things were known about these steps when the Lenski group last published on this topic (in 2008), the precise details remained unclear. What was needed was a complete characterization of the Cit+ bacteria through whole-genome sequencing to help indentify the changes. These long-awaited results are now available in a new paper published last month by the Lenski group, and they shed light on all three stages of the process.

Lights, camera, actualization

The key step - and the one of greatest interest - is of course actualization: the mutation that converted a Cit- cell to a Cit+ one. This is also one of the easiest steps to study, since the mutation provides the cell with a new feature that can be detected experimentally. Though E. coli cannot use citrate as a carbon source in the presence of oxygen, they are capable of using citrate in anoxic conditions (i.e. when oxygen is absent). To do so, they employ a protein that imports citrate in to the cell while at the same time exporting a compound called succinate. Since this protein is already present in the E. coli genome, it was long suspected that a genetic regulatory change that turned on its production in the presence of oxygen could be the key innovation that produced the first Cit+ bacterium in the culture. As we discussed yesterday, Behe notes that this change could result from a loss-of-FCT or a gain-of-FCT mutation:

“If the phenotype of the Lenski Cit+ strain is caused by the loss of the activity of a normal genetic regulatory element, such as a repressor binding site or other FCT, it will, of course, be a loss-of-FCT mutation, despite its highly adaptive effects in the presence of citrate. If the phenotype is due to one or more mutations that result in, for example, the addition of a novel genetic regulatory element, gene duplication with sequence divergence, or the gain of a new binding site, then it will be a noteworthy gain-of-FCT mutation.”

Interestingly, the actualization mutation was indeed a change of regulation of the anoxic citrate / succinate transporter, and it arose through a gain-of-FCT mutation. The mutation turned out to be a side-by-side duplication of the citrate / succinate transporter gene, as well as portions of two genes on either side of it. This imprecise duplication placed a partial fusion of these flanking genes next door to one of the copies of the citrate / succinate transporter gene. This brought the copy under the control of promoter sequences derived from of one of its neighbors, a gene that is active when oxygen is present. The resulting product was a copy of the citrate / succinate transporter gene that was now very weakly expressed in aerobic conditions. Since this is an example of a mutation that duplicates a gene and simultaneously creates a new regulatory element for it (causing significant sequence divergence), this is a clear-cut example of a gain-of-FCT mutation.

Responding to the data

While Behe has not yet, to my knowledge commented on this particular development within the LTEE, one of his colleagues in the Intelligent Design Movement (IDM), microbiologist Ann Gauger, has offered her thoughts. Two themes emerge in her commentary: that the Cit+ trait is “not new”, and that the number of mutations it required were within the bounds set out by Behe and another member of the IDM, structural biologist Douglas Axe:

When is an innovation not an innovation? If by innovation you mean the evolution of something new, a feature not present before, then it would be stretching it to call the trait described by Blount et al. in "Genomic analysis of a key innovation in an experimental Escherichia coli population" an innovation [...]

The total number of mutations postulated for this adaptation is two or three, within the limits proposed for complex adaptations by Axe (2010) and Behe in Edge of Evolution. Because the enabling pre-adaptive mutations could not be identified, though, we don't know whether this was one mutation, a simple step-wise series of adaptive mutations, or a complex adaptation requiring one or two pre-adaptations before the big event.

But does this adaptation constitute a genuine innovation? That depends on the definition of innovation you use. It certainly is an example of reusing existing information in a new context, thus producing a new niche for E. coli in lab cultures. But if the definition of innovation is something genuinely new, such as a new transport molecule or a new enzyme, then no, this adaptation falls short as an innovation. And no one should be surprised.

While Gauger does not speak to the tension between her description of the Cit+ mutation as “not genuinely new” and Behe’s criteria that this should be classified as a gain-of-FCT mutation, it is clear that she views this event as within Behe’s “edge” – i.e. within the bounds of “what Darwinism can do.” Additionally, she sees it as falling within the scope of what is evolutionarily possible as proposed by Axe’s work. In the next installment of this series, we’ll revisit how Behe defines his (claimed) limit of what evolutionary processes can accomplish, with this new evidence in hand. In doing so, a careful examination of the potentiation and refinement phases of the Cit+ transition will be informative.

In 1774, the French chemist Antoine Lavoisier replicated the relevant experiments in more controlled ways to demonstrate that mass was conserved during combustion. He also renamed the part of the air that burned 'oxygène.' English scientists resisted the French scientist's new name, not least because the English Priestly had already published his discovery of the gas. 'Oxygen' nonetheless entered the common English vocabulary in part due to one of the first popular science books, The Botanic Garden (1791), which included a poem praising the gas using the preferred French name. By coincidence, this book also promoted some early ideas about biological evolution (specifically, it suggested that sexual reproduction might be important to evolution, which might help to explain the popularity of a book of poems about science). It was written by Erasmus Darwin, the grandfather of Charles Darwin, who first proposed the modern form of the theory of biological evolution in his 1859 book, On the Origin of Species.

150 years later, we are discovering that the lines connecting evolution and oxygen run deeper than the Darwin family tree. We now know, for instance, that for roughly half of the Earth's 4.6-billion-years of history, there was little to no oxygen in the atmosphere. Instead, oxygen entered the atmosphere in two major pulses, with one between 2.4 and 2.2 billion years ago, and another between 0.8 and 0.54 billion years ago. Recent evidence suggests that the first pulse may have actually been the largest event in a series of fits and starts beginning at around 2.7 billion years ago that finally produced a stable low oxygen atmosphere by around 1.8 billion years ago.

Remarkably, both episodes of atmospheric oxygenation happened just before explosions in biological diversity. We have spotty evidence of unicellular eukaryotes (cells with nuclei) before 2.4 billion years ago, but the first fossil evidence for large, diverse eukaryotic communities comes at 1.5 billion years ago. If you are a human, this is part of your history; humans are multicellular eukaryotes descended from one of these early unicellular pioneers. Multicellular animal life is an innovation that seems to have required more oxygen: animals don't appear in the fossil record until about 0.61 billion years ago, toward the end of the second pulse of oxygen.

It is, perhaps, not surprising that major evolutionary events in the eukaryotic family tree, including the origin and diversification of the animals, would be tied to or even driven by major changes in atmospheric oxygen abundance. Eukaryotes generally, and animals specifically, are oxygen lovers. As the subjects of Mayow and Priestly died to prove, we require oxygen for respiration. In general, the larger and more organizationally complex we are (for instance, a human versus a slime mold), the more oxygen we require.

But where did all the oxygen come from? Ultimately, it was produced by the bacterial equivalents of the plants in Joseph Priestley's experiment, a group of photosynthetic microbes called the cyanobacteria. These bacteria are the first and only organisms to have evolved the ability to produce oxygen by photosynthesis. In fact, plants are able to photosynthesize only because their cells harbor descendants of one of the early cyanobacteria. We call them chloroplasts and think of them as little cellular organs, but they are actually the great-great-great... granddaughters of a cyanobacterium that long ago gave up its independence in exchange for the stable environment inside a eukaryotic cell. In any case, photosynthesis is the only known geological process capable of producing oxygen at the rates required for the two pulses of atmospheric oxygenation. The first pulse was probably largely accomplished by cyanobacteria, while the second pulse was probably mostly associated with the cyanobacterial denizens of eukaryotic algae.

What is remarkable about all of this is the extent to which modern life and the atmosphere are products of each other's evolution. The tiniest of photosynthetic organisms played one of the most important roles in shaping the sky, and the sky helped to usher in the age of animals! As a Christian and a geobiologist, I do not believe that this relationship is anticipated or predicted by the Biblical creation accounts.

But then again, why should it have been? The original audience for these accounts would have found concepts like bacteria or even oxygen incomprehensible. The people for whom the Bible was originally addressed thought about origins primarily in terms of ongoing national conflicts and the current human condition. Faced with a variety of violent creation myths that reinforced national conflicts, Genesis said that the universe was created to be good, peaceful, and orderly by one god. It specifically listed things worshipped by other nations as creatures of that god, and in the climax of the creation account, Abraham was called by the same god to be a blessing to all the nations through Israel.

I am not claiming that the Bible cannot be read in a way that can shape us in real and meaningful ways today. In fact, for those who believe that the Bible is inspired, part of the meaning of inspiration has to be that the Bible is God's powerful word to both those with no concept of modern science (most of the world's population, both today and in the past) and to those deeply engaged in its practice. But, and this is a big but, we contemporary Americans read the Bible best when we are sensitive to the assumptions of the original audience, carefully observe how the Bible transformed those assumptions, and look for opportunities to do the same thing with our thinking.

I think that it is important for Christians to reflect on the view of origins that science has given us in light of the thinking evident in the Biblical creation accounts. We have to do this because science gives us a story that is inherently without philosophical or theological meaning; it is up to us to give it meaning by understanding it in relationship with our beliefs. For instance, some see the evolutionary history of life and the Earth and give that history meaning by elevating chance and necessity to the level of prime actors in their own modern creation account. This meaning is not inherent to the theory of evolution; it is supplied by an atheistic belief system external to the theory. I suggest that this view mistakes created things (chance and necessity) for the Creator.

Others have preferred to see the regularity of the universe as the action of an orderly God. This is an old approach to natural theology that was popular among many early scientists, and saw God as responsible for doing such things as maintaining the planets in consistent paths around the sun. Still others look for God in the unexplained. This is a newer approach that sees God as acting primarily in short bursts not explainable by the regular, orderly function of the universe. Looking for God in these ways is a little like trying to capture him in a bell jar, an approach that worked perfectly well with oxygen for Mayow, Priestley, and Lavoisier, but one that is unlikely to impress the Creator described in the Bible.

I prefer to see the same history in the light of a God who desires to share aspects of his nature with his creation, notably including his creativity. Just as he has made humans to be creators (with a little 'c'), he has given the rest of our world the gift of being instrumental in its own creation through the process of evolution. This surely must have been part of what God saw when he described his creation as good! It is my hope that the modern American church can learn to see the goodness of creation in things like the evolutionary history of life and the atmosphere, as well.

This post first appeared in October 2009

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?”

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.”

Early this month, researchers from ENCODE released more than thirty papers presenting their findings. During a Science magazine online chat, the project’s data coordinator, Ewan Birney, explained the outcome:

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.

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.

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.

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.

According to the abstract of one of the lead papers from Nature, 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 some biochemical function. As a Science news article put it, these 30 papers “sound the death knell for the idea that our DNA is mostly littered with useless bases.”

The pro-Intelligent Design organization The Discovery Institute has heralded the discovery as the “demise of junk DNA.” Casey Luskin writes for their blog Evolution News:

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.

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.”

So with all this in mind, is ENCODE a stunning victory for ID, as Luskin believes? Bryan College biologist Todd Wood thinks not. He writes, “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.”

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—through the elegant processes of evolution, not in opposition to them.

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 post on our site, including a striking comparison between 29 different mammal genomes and the human genome). In fact, another ENCODE researcher participating in the Science magazine chat, John A. Stamatoyannopoulos of the University of Washington School of Medicine, thinks the findings align beautifully with evolutionary theory:

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.

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.
