        <description>In this series, Kathryn Applegate addresses the concern that randomness implies the absence of God&apos;s activity and involvement in the natural world.  She begins by clearing up some common misconceptions about the concept of &quot;randomness&quot;, and later focuses on the mechanisms of the immune system to demonstrate that God works through random processes to preserve life.  Far from being an indication of a &quot;godless&quot; universe, one might conclude that randomness is one of God’s favorite mechanisms for creating and sustaining life!</description>
        <content:encoded><![CDATA[<p>You hear it all the time: “That’s so random!” When used by people of my generation, the word “random” can simply mean “cool” or “surprising.” Or it can mean something like “disconnected,” as in the phrase, “I had a random thought” (which returns 189,000 hits on Google, by the way—random!).</p>

<p>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?</p>

<p>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.</p>

<p>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.</p>

<p>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 <em>indeterminate</em>, but is it purposeless? Not necessarily. Indeterminacy simply means the result cannot be predicted from the outset.</p>

<p>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.</p>

<p>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.</p>

<p>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.</p>

<p>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.</p>

<p>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?</p>

<p>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 <a href="http://models.scripps.edu/" target="_blank">model</a> as shown in the following video. In less than 30 seconds, you can watch a jumbled heap of proteins become a beautifully ordered structure.</p>

<p align="center"><object height="385" width="480"><param name="movie" value="http://www.youtube.com/v/X-8MP7g8XOE&amp;hl=en_US&amp;fs=1&amp;rel=0" /><param name="allowFullScreen" value="true" /><param name="allowscriptaccess" value="always" /><embed allowfullscreen="true" allowscriptaccess="always" height="385" src="http://www.youtube.com/v/X-8MP7g8XOE&amp;hl=en_US&amp;fs=1&amp;rel=0" type="application/x-shockwave-flash" width="480"></embed></object></p>

<p>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.”</p>

<p>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 <em>see</em> how it happens in a cell, but we can reconstitute the process in a test tube using different combinations of constituent molecules.</p>

<p>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:</p>

<p align="center"><object height="385" width="480"><param name="movie" value="http://www.youtube.com/v/YbpTusoDEgA&amp;hl=en_US&amp;fs=1&amp;rel=0" /><param name="allowFullScreen" value="true" /><param name="allowscriptaccess" value="always" /><embed allowfullscreen="true" allowscriptaccess="always" height="385" src="http://www.youtube.com/v/YbpTusoDEgA&amp;hl=en_US&amp;fs=1&amp;rel=0" type="application/x-shockwave-flash" width="480"></embed></object></p>

<p>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.</p>

<p>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 <em>un</em>intelligently-designed structures (like viruses, which can kill us), we see that God has made, and continues to oversee by his providence, a <em>good</em> creation that, at least in part, is capable of creating itself.</p>

<p class="intro">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.</p>]]></content:encoded>

        <title>A Plea to My Shepherds</title>
        <link>http://biologos.org/blog/a&#45;plea&#45;to&#45;my&#45;shepherds?utm_source=RSS_Feed&amp;utm_medium=RSS&amp;utm_campaign=RSS_Syndication</link>

        <description>... I would exhort these, my fellow conservative evangelical shepherds and thinkers, to set aside all reticence and fear, emerge from anonymity, and storm the forum of discourse, engaging this most pressing matter with vigor, equanimity, and humility. In doing so, know upfront that there will be few handrails to guide; you will not be building upon an extensive precedence of published conservative thought.</description>
        <content:encoded><![CDATA[<p>As I mentioned in my <a href="http://biologos.org/blog/scripture-vs-the-facts-working-through-a-crisis-of-understanding/">last post</a>, I’m deeply troubled by my fellow conservative evangelicals’ skepticism – even hostility – towards much of modern science, and believe that barring change, this disposition will prove spiritually catastrophic to our children and grandchildren, who are today being taught that assertions of an ancient universe and macro-evolution are unequivocally incompatible with the Cross of Christ, and tomorrow will enroll in universities that powerfully demonstrate the integrity of these scientific claims, thereby setting the stage for devastating crises of faith for countless thousands of young believers.</p>

<p>That said, I genuinely empathize with those who are reluctant to abandon traditional theological concepts for newer, still- developing ones. Given spiritual leaders’ biblical mandate to protect their families and congregations against error, a responsibility for which God will hold them strictly accountable (James 3:1), I respect their refusal to expose their flock to ideologies they regard as conflicting with the Word of God.</p>

<p>I further understand pastors and theologians’ resistance to tethering theology—which is meant to provide a solid epistemological foundation—too closely to that intrinsically dynamic endeavor called science. All humans need ideological stability, perhaps especially so with respect to spiritual matters. Recognizing this, pastors rightly ask why they should abandon or substantially revise an internally-consistent systematic theology that has served the church with relative stability for many hundreds of years. Science, on the other hand, is a realm for adventurers, groundbreakers, and ideological athletes intent on not just polishing or expanding today’s body of knowledge, but shattering it when necessary. Resounding with the jousts and clashes of competing ideas and arguments, and the stunning reversals of ideas once widely held, science often appears to be a messy–even tumultuous–business. Spiritual shepherds are insistent that the epistemological dynamism that necessarily characterizes science never become the mainstay of the Christian experience, which must be fundamentally stable and dependable. They see wisdom in maintaining a safe distance between the Church and the choppy waters of science.</p>

<p>The question, then, is whether the waters of scientific thought, particularly with respect to the age of the earth and evolution, have sufficiently smoothed out to warrant conservative thinkers’ taking a deeper look. Of course, the catch-22 here is that this can’t be answered without actually embarking upon an expedition of exploration and investigation, much as I recently did. Once undertaken, however, the conservative explorer will likely be confronted by a formidable problem:</p>

<p>As I can personally attest, navigating the crowded forum of wildly-differing ideas as to how to resolve the faith-science divide can be terribly daunting. Making this especially disconcerting for the conservative is the sobering reality that amidst the chorus of conflicting theories, one finds very little <em>substantive</em> published input from respected conservative theologians. As a result, the conservative seeker is sure to find herself awash in an ocean of seemingly novel theological “solutions” that are fundamentally antithetical to her evangelical sensibilities. This is likely to result in the impression that there is in fact no way to reconcile the findings of modern science with the key doctrines of orthodox Christianity, and hence the termination of the endeavor. Not only was this dynamic a constant challenge to me, but has proved a stumbling block to many would-be seekers that I personally know.</p>

<p>Whence then change? I believe the breakthrough will begin with a particular subgroup of conservative evangelical pastors, elders, and theologians. I know firsthand that there are many who, truth be told, have not been entirely at peace with their fellow conservatives’ summary rejection of—and apologias against—the findings of mainstream science. They have a gnawing sense that devastation looms for the Church and her children unless detachment yields to engagement, and rhetoric to substance. These have likely admitted to themselves that despite stridently asserting anti-evolution/old-earth views, they actually don’t understand these views in depth (nearly every conservative pastor and elder I’ve spoken with has conceded this). To date, these shepherds and thinkers have remained silent about their misgivings, reluctant to be perceived by their congregations and peers as betraying true Christianity. Given the astonishing fruitfulness of modern science and the comparative barrenness of young-earth creationism, I believe these evangelical leaders may now finally regard themselves as justified in stepping forward and publicly questioning whether the latter is in fact the view that a truth-revealing God would have His people believe.</p>

<p>Indeed, if I may, I would exhort these, my fellow conservative evangelical shepherds and thinkers, to set aside all reticence and fear, emerge from anonymity, and storm the forum of discourse, engaging this most pressing matter with vigor, equanimity, and humility. In doing so, know upfront that there will be few handrails to guide; you will not be building upon an extensive precedence of published conservative thought. Rather, you will be pioneers, with the open prairie of contemplation and consideration before you and the Word of God as a faithful, orienting star. The journey will be at times confounding, often scary, and never without challenge. Yet only through such robust, self-critical analysis will you find yourself in a posture where God can correct and refine all that He would, and only after which will you be able to pass on to your flocks a cogent, truly harmonious portrait of our Lord and His Creation that finds rich consistency between His written and natural revelations. I firmly believe that the fuller, more deeply informed portrait of the Lord and His universe that emerges from this investigation will fill your congregations with an unprecedented new sense of awe at our beloved God as Creator, and profoundly enhance their worship of Him. This has certainly been the result of my own journey.</p>

        <title>Science and Scientism in Biology: The Origin of Morality</title>

        <guid>http://biologos.org/blog/science&#45;and&#45;scientism&#45;in&#45;biology&#45;the&#45;origin&#45;of&#45;morality?utm_source=RSS_Feed&amp;utm_medium=RSS&amp;utm_campaign=RSS_Syndication</guid>
        <description>The problem is that as human beings, we know that goodness exists, so it must be accounted for, and if one is a staunch believer in scientism, it must be accounted for scientifically.</description>
        <content:encoded><![CDATA[<p>The idea that all current mysteries will eventually be solved using the scientific method has been called scientism. Stephen Barr describes scientism as the notion that “all objectively meaningful questions can be reduced to scientific ones, and only natural explanations are rational.” In biology, a subcategory of scientism is evolutionism, the concept that all biological questions (including those concerning the nature of humankind) are reducible to explanations derived from the Darwinian theory of evolution by natural selection.</p>

<p>One of the more outspoken proponents of this view is Sam Harris, a leading figure among the New Atheists, and a fierce antitheist. Harris has written a book and given talks on the idea that morality—broadly, the act of discerning good from bad—can be derived from science.</p>

<p>On the face of it, this seems strange, since the scientific consensus, especially in evolutionary biology, has always been that nature is morally neutral. We know, as scientists, that sharks are not “bad” any more than dolphins are “good.” The true evolutionary view (I always thought) was that fitness is related to success, not goodness.</p>

<p>The problem is that as human beings, we know that goodness exists, so it must be accounted for, and if one is a staunch believer in scientism, it must be accounted for scientifically. In some situations, this accounting seems to be possible. There is a large literature on kin selection as the basis for some kinds of altruism, and Dawkins has made the case that what he calls “misfiring of genes” for kin altruism are responsible for human goodness.</p>

<p>Harris claims that moral values can be based on scientific principles, and that no kind of cultural context, especially faith-based context, is necessary for humans to have a code of morals. He bases this argument on the idea that moral values are based on facts, and that these facts can be tested for their truthfulness. To some extent, this is an old idea. Murder, adultery, theft and lying—some of the best-recognized universal moral prohibitions, all tend to destabilize the coherence of social groups and would therefore be selected against in all societies.</p>

<p>But Harris goes much further, using arguments and examples that are anything but scientific. Since Harris is a leader of the antitheistic movement, and is interested in finding examples of religious practices that he believes can be scientifically proven to be immoral. He cites the abusive treatment of women in Islamic societies as a main example, and he mentions corporal punishment of children as a slap at Christianity.<br />
<br />
So how does Harris prove scientifically that forcing women to cover their bodies, and hitting school children with rulers are morally wrong? He doesn’t. Here is what he actually says:</p>

<blockquote>But we can ask the obvious question</em>:&nbsp;Is it a good idea, generally speaking,&nbsp;to subject children to pain&nbsp;and violence and public humiliation&nbsp;as <em>a way of encouraging healthy emotional development&nbsp;</em>and good behavior?&nbsp;<em>Is there any doubt&nbsp;</em>that this question has an answer,&nbsp;and that it matters?</blockquote>

<p>Harris clearly believes the answer to that question is no, and I agree with him. But where is the science here? Has he data to show that children who were subjected to corporal punishment had worse emotional development and behavior than children who did not undergo such punishment? No. He has no such data, and in fact while he considers the wrongness of corporal punishment to be an obvious fact, there are millions of people who consider it to be just the reverse. There is no science here; there is simply a basic underlying moral idea, which Harris shares with others.<br />
<br />
Harris touts the evils of Islamic fundamentalism as morally indefensible from a scientific point of view. But what kind of fact is it to say that making women cover their bodies is wrong, other than the “fact” that Harris thinks it is? Is there a science for determining the optimal way to treat women? If there is, it isn’t mentioned by Harris.&nbsp;<br />
<br />
While it may seem obvious that the oppression of women is morally wrong, proving scientifically that its disadvantageous to the thriving of our species is more tricky. In fact, the moral values of Harris, which are typical Western Judeo-Christian values, are largely counter-evolutionary. What we see when we look at history or sociology, is a background of true selection-positive behavior—indiscriminate killing of enemies, sexual aggression, concentration of power in a dominant faction—on which has been superimposed a moral code, followed and enforced despite its anti-evolutionary tendency. The real question to ask is: How is it that humans obey any of these moral codes that do not help them survive as individuals or as members of a culture?<br />
<br />
In truth, there is no science at all behind Harris’s grand claim of factual moral values, (beyond such obvious things as it isn’t a good idea to add cholera germs to the water supply). He even admits this by stating:</p>

<blockquote><p>Now the irony, from my perspective, is that the only people who seem to generally agree with me and who think that there are right and wrong answers to moral questions are religious demagogues of one form or another.</p>
</blockquote>

<p>Of course that is correct, because both Harris, and the people whom he calls “religious demagogues,” have formulated moral codes that they hold to in the absence of any “scientific” data.&nbsp;<br />
<br />
The argument that morality is outside the scope of science is not a hard one to make, but it isn’t only morality that must be excluded from the domain of science. The more important argument is that very few of the ideas of evolutionism are based on anything remotely scientific. This is because the evolutionism paradigm includes many distortions of Darwin’s great theory, and too many of these distortions have become accepted by an antitheistic academic culture without proper rigorous analysis.&nbsp;<br />
<br />
Like Steven Jay Gould, I see no evidence that the biological mechanisms of evolution by natural selection can be extrapolated beyond the bounds of biology. Gould devotes several chapters in&nbsp;<em>The Richness of Life</em>&nbsp;to attacking the “adaptationist paradigm,” which is a central part of evolutionism. In responding to Daniel Dennet’s assertion that adaptation and selection explain just about everything, Gould says:</p>

<blockquote><p>The fallacy of Dennet’s argument undermines his other imperialist hope that the universal acid of natural selection might reduce human cultural change to the Darwinian algorithm as well … The chief strategy proposed by evolutionary psychologists for identifying adaptation is untestable and therefore unscientific.</p>
</blockquote>

<p>Cunningham has also explored this issue in&nbsp;<em>Darwin’s Pious Idea</em>. Social Darwinism, eugenics, evolutionary psychology, sociobiology, mimetics and other nonbiological applications of Darwin’s theory are not rationally consistent with the fundamental properties of evolution by natural selection.&nbsp;<br />
<br />
Evolutionism has been used to “explain” all sorts of dynamics in culture, using evolutionary concepts. But, while the evolution of devices that play music (as an example) might bear a resemblance to the evolution of carnivores, it is a superficial resemblance. Devices do not replicate themselves, so they cannot be the target of selection.&nbsp;<br />
<br />
Scientism is a failed philosophical approach to the pursuit of universal truth. Its failure should be evident especially to scientists who, more than most, understand the limits of their fields of study, as well as the enormous effort it takes to wrest nuggets of pure truth from nature. We must, as previous generations of enlightened thinkers have done, admit that issues of morality, beauty, thought, love, art, and culture are not approachable by scientific methodology or tools, or we risk losing a huge part of our human endowment of special (if not divine) genius.</p>

        <description>Once we have a scientific hypothesis for how something exists, it is tempting to make the philosophical inference that this is also why it exists.</description>
        <content:encoded><![CDATA[<p>Once we have a scientific hypothesis for <em>how</em> something exists, it is tempting to make the philosophical inference that this is also <em>why</em> it exists.  Richard Dawkins (1976), as well as Michael Ruse and Edward O. Wilson (1993), do this in the evolution of human morality.  Scientifically, they hypothesize that, once humans started living in large, complex social groups, individuals whose genes made them constantly selfish were punished by the group and therefore produced fewer offspring than individuals whose genes made them believe in an objective moral code. Moving into philosophy, Ruse and Wilson (1993) write,</p>

<blockquote>Morality, or more strictly our belief in morality, is merely an adaptation put in place to further our reproductive end.</blockquote>

<p>Important scientific theories invite philosophical and theological reflection. Dawkins, Ruse, and Wilson, have described their conclusions. But scientific theories are often compatible with multiple philosophical and religious interpretations. For example, Newton's laws of motion and gravity allow several competing theistic and atheistic interpretations.</p>

<p>To avoid Ruse and Wilson's philosophical conclusion, we need not dispute their scientific hypothesis about how morality evolved. We need only dispute their philosophical extrapolation as to why morality exists. Even if we restrict ourselves to an atheistic worldview, this extrapolation is questionable.  Donald MacKay (1965) would call this an example of "the fallacy of nothing but-tery".  This is the assertion that a description of something at one level renders other levels of description meaningless.  From our everyday experience, we know that a successful description on one level does not invalidate other levels of description.  For example. one might assert that a Shakespeare sonnet is "nothing but" ink blots on a page (MacKay 1965).  True, one way to describe a sonnet is to precisely specify the page coordinates of every ink blot.  This description is valid and complete on its own level; however, one could also analyze the sonnet linguistically, emotionally, socially, historically, and on other levels.  If one is programming an inkjet printer, the most important description is in terms of ink blot coordinates. For almost every other purpose in life, however, that is an unimportant level of description.  In the same way, a complete evolutionary description of the existence of morality does not necessarily invalidate the truth, utility, or significance of other levels of description of morality.</p>

<p>If we do not restrict ourselves to atheism and instead allow for the existence of a creator, the extrapolation from <em>how morality evolved</em> to <em>why morality exists</em> fails further. Consider an analogy.  Suppose an inventor builds a robot which could do a variety of useful things-- mow the lawn, clean the house, grade homework, write book chapters, and so on.  One thing this robot can do, given a complete set of spare parts, is build a replica of itself.  Whenever the inventor needs another robot, she gives one robot a set of spare parts and has it build a replica of itself.  Amongst all the software subroutines within this robot, there is a set of subroutines that govern the robot's self-replication, including the replication of those self-replication subroutines.  Would it be correct to say that the purpose of the robot's existence is merely to reproduce those particular self-replication subroutines? Do all of the other software and hardware of the robot--which allow it to mow the lawn, and so on-- merely further the reproductive ends of those self-replication subroutines? At one level, the robot's hardware and software do serve to reproduce those self-replication software routines.  At another level of analysis, however, those self-replication software routines serve the robot to produce more copies of itself.  At still another level, those self-replication software routines serve the robot's creator.  The creator of the robot should get the last world as to which of those levels of description is most important.</p>

<p>In humans, does morality exist to further the reproduction of certain genes, or do those genes exist in order to allow for the production of new human beings who can behave morally? If human beings have a creator, the creator gets the final word on the question of purpose.  The mechanism which the creator used to make those genes-- whether <em>de novo</em> or via evolution-- is secondary.  The creator's purpose in creating those genes decides the issue.</p>

        <description>In this three&#45;part series, Cal DeWitt offers insights and examples of why science and ethics must work together to help us make informed, practical decisions within our society.  DeWitt’s science&#45;ethics&#45;praxis model provides a framework by which we can live more effectively as God’s stewards.</description>
        <content:encoded><![CDATA[<h3>The Science-Ethics-Praxis Triad</h3>

<p>Today, as I write, I am no longer in the desert of southern California, nor in the beech-maple forest of New Hampshire, but on a glacial drumlin in Waubesa Wetlands—a large marsh four miles south of Madison, Wisconsin. Here Ruth and I have our home, and here I study creatures whose watery habitats my neighbors and I have worked to save from eventual destruction. While my desert study site now is covered by a city where people live alone in the land—absent the desert creatures—my wetland study site remains occupied by all kinds of native plants and animals. Embracing it is the Town of Dunn, whose land stewardship plan helps people understand, serve, and maintain this and the other ecosystems. Our town stewardship plan encourages restoration of the landscape, protects agricultural lands, and strives to transmit an intergenerational heritage of secure and wholesome homes, livelihoods, and habitats for the animals, plants, and people that live here. We live largely in harmony and accord. </p>

<p>House-building on slabs poured onto desert sands first alerted me to the question of praxis, the third point on the napkin. But it was later, in my work as organizer of the Waubesa Wetlands Scientific and Agricultural Preserve, and as supervisor and later as chair of the Town of Dunn, that I came to realize that science and ethics do no earthly good unless put into practice. In serving my town, I came to apply what I had learned in the desert: praxis uninformed by science and ethics usually creates more problems than are solved.</p>

<p>“How do you put it all together?” those students in New Hampshire wanted to know. For me, it was building a framework for stewardship that simultaneously considered the questions “How does the world work?” “What is right?” and “What then must we do?” This science-ethics-praxis triad is a framework for living, for learning, for teaching, and most importantly for acting. It is a framework for stewardship.</p>

<p>In order to live and act rightly in the world, we need to know how the world works. We need to know how the systems that sustain us work, and how we interact with them. Without such knowledge we could drown in a flash flood, have our homes undercut by desert winds, cross the street in the path of an oncoming car, or get sick from consuming foods with toxic ingredients. As human beings develop more and more of the world, and as the reach of human actions extends regionally and globally, our knowledge must increase accordingly. This knowledge is not limited to what we acquire from a formal education; it also includes the knowledge we gain from family and friends, and from experience and experiment. In order to live and act rightly in the world, we need to know how the world works.</p>

<p>In order to live and act rightly in the world, we need to know what we ought to do. A century ago, this question was addressed in many colleges across America in a course for graduating seniors on moral philosophy. The purpose of this course was to convict students that they should apply their knowledge for the pursuit of good instead of pursuing self at others’ expense. At my university, this aspect of college education is expressed in a quotation from Abraham Lincoln carved in stone on a bench behind Lincoln’s statue at the top of Bascom Hill: “Let us have faith that right makes might, and in that faith, dare to do our duty.” The question “What is right?” is represented by the ethics corner of our triad. Moving directly from the Science corner to the praxis corner, or from the ethics corner to the praxis corner, proves problematic, even disastrous. Consider the result of going from knowledge of nuclear fission (science) directly to producing and dropping an atomic bomb (praxis), or moving from the belief that death is bad (ethics) to removing dead wood from forests (praxis); both are examples of these disastrous shortcuts.</p>

<p class="caption-left"><img src="http://biologos.org/uploads/static-content/DeWitt_Cover_thumb.jpg" alt="" height="270" width="200"  /></p>

<p>But knowing the science and observing the ethics of this stewardship framework does absolutely no good if it is not put into practice—placed into service. By themselves, the very best science and the most substantial ethics are no substitutes for action. We need to act appropriately and deliberately in the light of scientific and ethical knowledge. Praxis by itself, without being grounded in science and ethics, results in mere activism—activism that is unlikely to do good and that may produce harm. All three corners of the triad are essential—but not by themselves. Taken together and working interactively, they provide a framework for stewardship.</p>

<p>But will these three operate in dynamic interaction? Will they interact in ways that preserve and achieve the integrity of human life and the environment? The answer depends on what we know and understand about ourselves and the world (science), what we believe we should do (ethics), and what we in fact do, and how we respond to our successes and failures (praxis). It depends on our will, our motivation, our determination, and our dedication to strive for a harmonious world of creatures before their Creator. What might make us strive for such a world?</p>

<p class="intro">Part 3 explores the challenge of translating ideals into concrete actions.</p>

        <title>Series: To Serve and Preserve—Genesis 2 and the Human Calling</title>

        <guid>http://biologos.org/blog/series/to&#45;serve&#45;and&#45;preservegenesis&#45;2&#45;and&#45;the&#45;human&#45;calling?utm_source=RSS_Feed&amp;utm_medium=RSS&amp;utm_campaign=RSS_Syndication</guid>
        <description>In this series, David Buller pays careful attention to the original language and cultural context of Genesis 2, revealing that our responsibility to care for creation is a sacred task given to us by God, not merely a modern secular activity.  By taking Scripture seriously, we learn that we have a God&#45;given mandate to be diligent stewards of His creation.</description>
        <content:encoded><![CDATA[<p>The Bible provides us with several beautiful, theologically rich accounts of creation – in Genesis 1 and 2, but also in the Psalms and Job as well. If I had to pick a favorite from these passages, I think I’d choose Genesis 2, which tells the story of creation by zeroing in on the creation of humanity and a garden somewhere “in the East.” This chapter is packed with theological truths, yet we unfortunately often miss them; we may think of this chapter as less significant than Genesis 1, or merely as a setup for Genesis 3. At the same time, our curiosity about scientific matters (and blindness to symbolic language) might predispose us to skip right over the theological truths that this passage teaches. But if we approach Genesis 2 on its own terms, what might we learn from it?</p>

<p>A careful study of this chapter is important because it gives us a beautiful picture of the proper relationships we should have with God, the natural world, and each other. Numerous posts could be written on each of these relationships, but in this post I’d like to focus on how Genesis 2 describes our relationship to the rest of creation. These relationships are given deeper significance when we recognize that the garden is being described as a temple-like “sacred space,” not just an ordinary garden. There are numerous clues in the passage that this is the case. John Walton writes that the Garden/temple parallels “are givens that are simply assumed by the author and audience”<sup> 1</sup> of Genesis, but we completely miss them if we take fail to read the text the way the ancient author and audience would have.</p>

<h3>Temples and Gardens</h3>

<p>In the Ancient Near East (ANE), all sacred space was conceived of as something like a temple; it was a place where humans would serve God and experience their closest access to Him.  Thus in ANE cultures, a temple complex was seen as being the apex and a microcosm of creation and the earthly abode of the god(s). Descriptions of temples often pictured a river flowing from under the temple and flowing out through an adjacent garden, symbolizing the fertile extravagance of the divine provision. A temple garden would be no mere backyard vegetable patch, but rather an elaborate, beautifully landscaped botanical park.</p>

<p>The same temple/river picture can be seen in the description of the eschatological temple in Ezekiel (ch. 47) and Revelation (chs. 21-22, where the final temple is God Himself). Sound familiar? In Genesis 2 we also have a river flowing “from Eden [‘Abundance’] to water the garden” (v. 10).<sup>2</sup> Not only is the Garden filled with “every beautiful tree with edible fruit” (v. 9), but the area itself is rich with gold, resins, and gemstones (sometimes translated “bdellium and onyx”), the same materials later used to decorate Israel’s tabernacle, temple, and priestly garments. Furthermore, many scholars are convinced that the design of temple’s Menorah (candlestick) deliberately echoes the Garden’s Tree of Life, and some also think that the Ark of the Covenant in the temple parallels the Tree of the Knowledge of Good and Evil.<sup>3</sup></p>

<h3>Made for Sacred Service</h3>

<p>As inhabitants of this temple-garden, it comes as no surprise that Adam and Eve enjoyed a special closeness to God’s presence (Gen. 3:8 pictures God taking an evening walk through the Garden). But as inhabitants of the Garden, they had special responsibilities as well; they were told “to farm it and take care of it” (v. 15). The two Hebrew words used here have a broader range of meaning than their English translations suggest. As John Walton writes, the broader meaning of the word here translated “to farm” (particularly when used in a sacred context) “is often connected to religious service deemed as worship (e.g., Ex. 3:12) or of priestly functionaries serving in the temple precinct (e.g., Num. 3:7-10).”<sup> 4</sup></p>

<p>The usage in Genesis 2 seems to have two layers of meaning: “farm/cultivate the Garden” (since it is an agricultural space) and “serve/worship God” (since the Garden is also a sacred space). The dual meanings are as intertwined in Hebrew grammar as they are intended to be in practice. The second Hebrew word (translated “take care of”) has a deeper religious meaning as well. The word can refer to protecting farmland from external threats, but in a danger-free sacred space like the Garden, the word more generally refers to “performing duties on the [temple] grounds,” that is, to “sacred service.”<sup>5</sup></p> 
 
<p>Walton therefore translates these two Hebrew words as “serve and preserve.”  These same words appear again together several times in Numbers to describe the priest’s duties in the temple.  Because of all this, Gordon Wenham describes Adam as “perhaps…an archetypal Levite” with a “quasi-priestly” role in the garden.<sup>8</sup>  Eve was created as Adam’s companion and “helper” in his work, a word which nowhere in the OT refers to a subordinate assistant, but rather to one who is at least equal to the one being helped.<sup>9</sup></p>

<p>Genesis 2 should banish from our minds any idea that creation care is somehow “secular” work for a Christian, or that it is not even our responsibility. This was the first task given to humanity, to serve and worship God by cultivating and protecting the natural world. The centrality of our responsibility in this regard is even clearer when we back up to the beginning of the chapter. We know there was a river “flow[ing] from Eden to water the garden” (v. 10), symbolizing that “all fertility emanates from the presence of God.”<sup> 10</sup> Nonetheless there could be no cultivated plants in the garden because “there was still no human being to farm the fertile land” (v. 5). With no gardener and no rain, the ground was watered indiscriminately; a human was needed to irrigate the waters and support a garden.<sup>11</sup> Therefore, God “formed the human from the topsoil” (Hebrew wordplay equivalent to “human from the humus”) before planting the garden. God certainly could have watered it another way without needing us, but He chose not to, and the resulting collaborative picture here is a beautiful one. All provision flows from God, but He has chosen to give us an essential part in further channeling his provisions in the natural world. Far from countering God’s creative work by destroying nature, we are intended to work with Him to preserve and further it.</p>

<p>Of course, though created primarily to glorify God, the world was also made to provide us abundantly with the food and resources that we need to live (Gen. 2:16). Yet we don’t need to look far to see that we have often failed in our responsibility to properly care for creation. We live in a fallen world, and sin has fractured the intended harmony of our relationships with God, creation, and each other (as described in Genesis 3:14-24).</p>

<p>I recently heard a striking crystallization of this fallen perspective in Spencer Tracy’s narration in the opening scene of the sprawling 1962 western film “How the West Was Won.” As the camera flies over majestic Western fields and mountains, the narrator tells us that “This land has a name today, and is marked on maps. But the names and the maps all had to be won, won from nature and from primitive man.” This is the fallen perspective – advancing our human purpose on earth is done through <em>defeating</em> nature and other people (derogatively labeled “primitive,” as well) apart from God. This perspective perfectly illustrates the conflict-based relationships that sin brings about, already described for us back in the first chapters of the Bible.</p>

<p>Are we doomed, then, to live helplessly in this way? If this is just the way the world is and the way we are, shouldn’t we just accept that? Apart from Christ the answer would be “yes,” but the New Testament makes it clear that though we are still fallen, the saving work of Christ has brought about a profound change in us. As N.T. Wright makes clear in his book <em>Surprised by Hope</em>, Jesus taught (and the Resurrection vindicated) that the Kingdom of God “was and is breaking in to the present world, to earth.”<sup> 12</sup>  Christ’s Resurrection was the first act of the future new creation. If we are truly “born again” into this new reality, this new way of living, we must strive (in the Spirit’s power) to live lives of wholeness and right relationships, putting our sinful nature to death (Colossians 3). In doing so, we would be wise to include Genesis 2 as we seek to follow God’s will and God’s Kingdom, “on earth as it is in heaven” (Matt. 6:10).</p>

<p class="intro">In part 2 of this series, David describes how Genesis 1, Genesis 2, and modern scientific accounts offer complementary and mutually enriching perspectives in our understanding of God's creation.</p>

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

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

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

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

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

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

<h3>Interpretive communities</h3>

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

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

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

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

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


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

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

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


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

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

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

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

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

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

<h3>Notes </h3>

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

        <description>It is not uncommon to hear voices proclaiming that biology and physics have shown us that—at fundamental levels—nature is random, hence meaningless, purposeless, and without a creator.  But how might God work providentially through indeterminate processes?

        <content:encoded><![CDATA[<p>It is not uncommon to hear voices proclaiming that biology and physics have shown us that—at fundamental levels—nature is random, hence meaningless, purposeless, and without a creator.  In fact, chance (or randomness) has often been seen as inconsistent with Christian faith by Christians, too, not just by those opposed to faith.  For instance, none other than John Calvin wrote:</p>

<blockquote><p>Suppose a man falls among thieves, or wild beasts; is shipwrecked at sea by a sudden gale; is killed by a falling house or tree.  Suppose another man wandering through the desert finds help in his straits; having been tossed by the waves, reaches harbor; miraculously escapes death by a finger’s breadth.  Carnal reason ascribes all such happenings, whether prosperous or adverse, to fortune.  But anyone who has been taught by Christ’s lips that all the hairs if his head are numbered [Matt. 10:30] will look further afield for a cause, and will consider that all events are governed by God’s secret plan. </p></blockquote>

<p>In this passage, Calvin presents belief in “fortune” as evidence of carnal reasoning, and statements like this one have contributed to a widely-held notion that modern scientific understandings of the role that randomness plays in nature is inconsistent with belief in divine providence.  In other words, if “randomness” equals blind and capricious “fortune,” then how can God be said to be working all things to his ends? </p>

<p>But Calvin could not have known of the very different understanding of randomness held by today’s scholars. Physical scientists, mathematicians, and statisticians have not yet agreed on a single unambiguous definition of the term “randomness,” but among these scientists, the term consistently refers to a family of related concepts focusing on <em>unpredictability of the outcomes of single events and the absence of pattern in sequences of outcomes</em>.  I like this statement by John Polkinghorne, “Chance doesn't mean meaningless randomness, but historical contingency. This happens rather than that, and that's the way that novelty, new things, come about.”  In Polkinghorne’s view, chance is an agent of creativity and can be perceived as being purposeful. </p>

<p>In fact, there are abundant examples of phenomena in nature in which randomness plays a role one could understand as being purposeful.  For example, osmosis is a marvelous mechanism that enables all 10 trillion cells in our bodies to be nourished – it depends on the random motion of molecules.  The human immune system is able to defend the body against attacks from millions of different microorganisms using a relatively small number of building blocks and random combinations of these to fashion defenses specific to each adversary.  We never take a breath and find it to be all nitrogen or carbon dioxide – random motion of molecules keeps oxygen close to uniformly distributed throughout the atmosphere.  </p>

<p>In 2007, a British statistician, David Bartholomew published <em>God, Chance, and Purpose</em> in which he argues that God “can have it both ways”—that he can use low level randomness to accomplish divine purposes while simultaneously maintaining order at a higher level.  Of course, we cannot prove that God ordained these random processes to achieve divine purposes in the world.  But to a person of faith, such an interpretation in both consistent with the observations we make in science and with the Scriptural notion of God’s providential care for the world.</p>

<p>Considerations like these led the John Templeton Foundation to provide a generous grant of $1.69 million to support a new research initiative on the theme of Randomness and Divine providence.  Beginning this past summer, the program has the purpose of providing support for solid theoretical exploration of the kinds of ideas and possibilities expressed above—involving theology, philosophy, natural science, mathematics, and statistics.  The grant will support individual scholars and teams of scholars who are willing to devote a significant amount of time between March of 2013 and June of 2015 to such work, and the project’s request for proposals suggests the following as questions researchers might pursue:</p>

<ul><li>How might God work providentially through indeterminate processes?  Can recent advances in understanding the nature of randomness offered by algorithmic information theory, physics, biology, and other sciences provide insight into this question?</li>
<li>Can we bring clarity to the concept of "randomness"?  Philosophers and scientists have tried on occasion to give precise definitions of when a process is random, but more work needs to be done on the question.  How do (or should) conceptions of randomness vary across academic disciplines?</li>
<li>What are some possible implications of randomness for hiding or unfolding divine creativity and purpose in the world?  Could God use randomness to (1) generate creativity, (2) hide divine actions, or (3) unfold information? Why might God do so?</li>
<li>How might we identify and come to understand a significant collection of nondeterministic processes in which agents could intentionally employ randomness to bring about purposeful results?</li>
<li>How might we mathematically and physically model random processes in ways that help us understand how divine providence could be exercised in a "chance-governed" world?</li>
<li>How do "laws and orders" in nature interplay with "chance and randomness" in bringing about results that can be interpreted as aspects of divine providence?</li>
<li>Might randomness be evidence of limitations in human knowledge but nothing more?  Or might it be evidence of ontological indeterminism?  Might this be tested?</li>
<li>What implications does randomness have for aspects of God’s relationship with the physical world such as God’s relationship to time and God’s role in causation?  How might randomness be reconciled with God’s foreknowledge?</li>
<li>How might an understanding of providence based on an extended Molinism and/or open theology incorporate randomness?  For example, could an extended Molinism provide a plausible account of the relationship between quantum mechanics and divine providence?</li>
<li>What are some theodical implications of randomness, particularly for the issue of natural evil?</li>
<li>How have the theological traditions of Augustine, Maimonides, Aquinas, Luther, and Calvin addressed chance and fortune?  In what ways might they incorporate ontological randomness?</li>
<li>How do or could religions other than the Judeo/Christian tradition understand and incorporate randomness?</li>
<li>How is the concept of randomness understood by advocates of secularism, naturalism, and new atheism?  What are the strengths and weaknesses of these usages?</li>
<li>How might an understanding of randomness in the world alter our conceptions of divinity, especially our understanding of divine providence?</li></ul>

<p>Despite the range of issues mentioned above, research is by no means restricted only to these topics. In fact, the structure of the program is designed to foster collaboration and build community between scholars, with the end of expanding the range and integration of their work: two conferences will be held to bring scholars together with each other and then with members of the public—one at Calvin College in 2013 and the other at Fuller Theological Seminary in 2015. To get more information and to learn how to submit a proposal, see the <a href="http://www.calvin.edu/mathematics/randomnessproject/">project website</a>; then join us in exploring the truth that all creation glorifies God—even randomness!</p>

        <description>Charles Darwin’s personal struggles and ultimate rejection of Christianity are well documented, and people are eager to link his loss of faith to his evolutionary theory.  David Lack, on the other hand, began his scientific career as an agnostic, but shortly after publishing his famous book on the evolution of &quot;Darwin&apos;s finches&quot;, he converted to Christianity.</description>
        <content:encoded><![CDATA[<h3>David Lack</h3>

<p>In my previous <a href="http://biologos.org/blog/david-lack-and-darwins-finches" Target=”_blank”>essay</a>, I discussed “Darwin’s finches” and how surprisingly little Charles Darwin himself had to say about them.  In fact, it was actually the British ornithologist David Lack (1910-1973) who conducted the critical research that immortalized the finches in biology textbooks and popular lore.  In 1973, the eminent German zoologist <a href="http://www.achievement.org/autodoc/page/may1pro-1" Target=”_blank”>Ernst Mayr</a> wrote:</p>

<blockquote>Already well known among professional ornithologists, his work on the Galapagos finches gave David Lack world fame… There is no modern textbook of zoology, evolution or ecology which does not include an account of his work.<sup>1</sup></blockquote>

<p class="caption-left"><img src="http://biologos.org/uploads/static-content/320px-Ernst_Mayr_PLoS.jpg" alt="Ernst W. Mayr" height="218" width="320"  /></br>Ernst W. Mayr</p>


<p>Decades have passed since Mayr wrote these words, and David Lack’s name has largely faded from public discourse.  On the other hand, the Galapagos finches have become one of the most recognized symbols of evolution in the world today.  Does it really matter whether Lack or Darwin gets credit for describing the evolution of these remarkable birds?</p>

<p>Insofar as evolutionary theory contrasted with religious belief, it makes a <em>big</em> difference. In a culture that is eager to equate evolution with atheism, it should come as no surprise that these birds are only known as “Darwin’s finches”.  Darwin’s personal struggles and ultimate rejection of Christianity are well documented, and people are eager to link his loss of faith to his evolutionary theory.  David Lack, on the other hand, began his scientific career as an agnostic, but shortly after publishing his famous book on the evolution of Galápagos finches, he converted to Christianity! <sup>2</sup></p>

<h3>A Christian at the forefront of evolutionary biology</h3>

<p>Lack’s Christian conversion did not mark the end of his scientific achievements, either.  In fact, he continued as a prolific researcher until just weeks before he died.  Among his many achievements, he was Director of the Edward Grey Institute of Field Ornithology (1945-1973), Fellow of the <a href="http://en.wikipedia.org/wiki/Royal_Society">Royal Society</a>, and President of both the International Ornithological Congress (1962-66) and the British Ecological Society (1964-65).  His fellow scientists held him in great esteem:</p>

<blockquote>He was described as one of the most outstanding among world ornithologists; he was certainly this, but he was also one of the world’s leading evolutionists.  All the time one saw developing his use of birds as material for the study of wider, deeper, biological problems.<sup>3</sup></blockquote>

<p class="caption-right"><img src="http://biologos.org/uploads/static-content/Lack_Chimney.png" alt="David Lack in search of Chimney Swifts" height="206" width="288"  /></br>David Lack at the International Ornithological Congress, 1962.</p>

<p>Clearly David Lack was an outstanding scientist, and his commitment to Christianity did not tarnish, hinder, or undermine his research on evolution.  But we might also ask, what was Lack like as a Christian?  Did he keep his faith hidden from view, afraid that it might compromise his reputation as a scientist?  Ernst Mayr, who interacted with David Lack professionally and personally for nearly 40 years, had this to say:</p>

<blockquote>I have known only few people with such deep moral convictions as David Lack. He applied very high standards to his own work and was not inclined to condone shoddiness, superficiality and lack of sincerity in others. This did not always go well with those who preferred to compromise in favour of temporary expediency. David had been raised in an environment in which great stress was layed on moral principles and this attitude was later reinforced by his Christian faith. This explains his extraordinary unselfishness and modesty, and his great devotion to his family, to his students, to his friends, and to all the things that he lived for. The equanimity, indeed serenity, with which he faced death after his terminal cancer had been diagnosed is further evidence of the strength which his faith gave him.<sup>4</sup></blockquote>

<p>Like Asa Gray<sup>5</sup> before him, and Francis Collins<sup>6</sup> after, David Lack was an sincere, devout Christian, as well as a leading scientist who employed evolutionary theory to make brilliant discoveries about the natural world.  Though Lack did not see any conflict between his scientific and Christian beliefs, he was sympathetic to the concerns of his fellow Christians.  Therefore, ten years after publishing his masterpiece on <em>Darwin’s Finches</em>, Lack wrote another book entitled <em>Evolutionary Theory and Christian Belief: The Unresolved Conflict.</em></p>

<p>Originally published in 1957, this book deals with the very same science and faith questions that Christians struggle with today— topics like randomness and chance, death in nature, miracles, and evolutionary ethics.  While it would be unreasonable to expect anyone to completely resolve these matters, Lack offered numerous insights both as a devout Christian and one of the world’s leading biologists.</p>

<p>Let’s take a brief look at how Lack addressed some of these questions.
</p>

<h3>Blind Chance or Divine Plan?</h3>

<p>Evolutionary theory does not invoke supernatural forces in explaining the history of life on Earth; instead, it relies on naturally-occurring processes to account for the vast diversity of life.  Additionally, it explains animal behavior largely in terms of survival and reproduction, without appealing to any higher purpose of life.  Taken together, does this imply that God is absent, and that our lives are ultimately meaningless?</p>

<p>David Lack responded,</p>

<blockquote>Behind the criticism that Darwinism means that evolution is either random or rigidly determined lies the fear that evolution proceeds blindly, and not in accordance with a divine plan.  This is another problem that really lies outside the terms of reference of biology.  It is true that biologists have inferred that, because evolution occurs by natural selection, there is no divine plan; but they are being as illogical as those theologians whom they rightly criticize for inferring that, because there is a divine plan, evolution cannot be the result of natural selection.<sup>7</sup></blockquote>

<p>When rendering judgment on the ultimate meaning of life, biologists are speaking from their person beliefs, not from scientific authority.  Moreover, Lack pointed out that many science enthusiasts have employed the concept of “randomness” in ambiguous and misleading ways:</p>

<blockquote>Mutations are random in relation to the needs of the animal, but natural selection is not.  Selection, as the word implies, is the reverse of chance.<sup>8</sup></blockquote>

<div class="see-also">See more about <a href="http://biologos.org/blog/evolution-is-god-just-playing-dice2">randomness and divine governance</a>.</div>

<p>In support of his view, Lack pointed out that <a href="http://www.mapoflife.org/about/convergent_evolution/?section=0">convergent evolution</a> has produced uncanny resemblances between distantly-related species across the world, notably among marsupials in Australia.  Different evolutionary trajectories can lead to very similar results.<sup>9</sup></p>

<h3>Death in Nature</h3>

<p>After addressing concerns about the seeming “randomness” of evolution, Lack turned to another great concern, the role of death in natural selection:</p>

<blockquote>Various writers–some Christian and others agnostic–have been troubled about natural selection not only because it seems too random, but also because it is so unpleasant.<sup>10</sup></blockquote>

<p class="caption-left"><img src="http://biologos.org/uploads/static-content/fossilgraveyard_square.jpg" alt="" height="247" width="250"  /></br>Image courtesy John Marsh Photography via Flikr</p>

<p>Genetic mutations are generally harmful, and for evolution by natural selection to produce new forms of life, an awful lot of organisms must die.  For many Christians, it is inconceivable that a loving and merciful God would allow death on such a vast scale.</p>

<p>But Lack also pointed out that rejecting evolutionary theory doesn’t actually get rid of the problem of death.  Regardless of what we think about evolution, the brute fact of <a href="http://science.nationalgeographic.com/science/prehistoric-world/mass-extinction/">mass extinction</a> remains.  Fossils of innumerable animals, plants, and microorganisms clearly demonstrate that the vast majority of species that have ever lived are now dead.  It may be quite troubling for us to observe that our planet is a giant graveyard of natural history, but rejecting evolution will not change this fact. 

<p>Some Christians conclude that death could not have been part of the divine plan; instead, it must be the work of the devil, or the result of human sin.  But this interpretation contains an implicit assumption that death is always evil.  Is this really true?  David Lack offered two intriguing insights:</p>

<div class="see-also">See more on <a href="http://biologos.org/questions/death-before-the-fall">death and the Fall</a>.</div>

<p class="caption-right"><img src="http://biologos.org/uploads/static-content/greencourtship.jpg" alt="" height="241" width="240"  /></br>Blue-cheeked Bee-eater (Merops persicus) pair in<br /> courtship, seen in Basai, Gurgaon, India.<br /> Image courtesy <a href="http://www.flickr.com/photos/kkoshy/">Koshy Koshy</a>.</p>

<ol><li>For a population to maintain a stable size, all births must be balanced by a corresponding number of deaths.  A world in which no animals die is a world in which no animals are born.  That means no reproduction, no courtship, and by implication, no singing birds—much to the dismay of ornithologists and people in love! </p>

<li>Some people, taking cues from Isaiah 11:6-7, suppose that in a perfect world, animals only eat plants.  But in fact, plants themselves depend on the bacterial decay of dead organisms.  If animals didn't die, then essential nutrients would disappear from the ground, and plants could not continue to grow. Eventually, there would be nothing left for animals to eat, and all life would cease.<sup>11</sup></li></ol>

<h3>Miracles</h3>

<p>Many Christians are uncomfortable with evolutionary theory because it denies a miraculous, supernatural origin of life.  They fear that if those miracles are denied, it might lead people to reject the possibility of miracles altogether, including the central feature of the Christian faith—the resurrection of Jesus from the dead.</p>

<p>As a devout Christian, David Lack certainly affirmed the fundamental tenets of the gospel.  But at the same time, he explained to his readers that invoking miracles to account for unusual features of the natural world is not particularly helpful when trying to deepen our understanding of God’s great multitude of creatures:</p>

<blockquote>[The biologist's] research depends on repeated observations.  It need not, as popularly supposed, consist solely, or even mainly of measurements and experiments, but unless events are repeated, they cannot be assessed by science.  Hence truly unique events come outside the domain of science, though biologists are not usually convinced when told they must, therefore, leave such problems as miracles to others.   For one of the chief ways in which research has advanced is through the discovery of apparent exceptions to the known rules, and if further study shows the exceptions to be replicable, new regularities are revealed from which modified rules can be propounded.  This method has been so successful that the biologist tends to doubt whether there are any types of irregularity, or seeming irregularity, that will not yield to it.<sup>12</sup></blockquote>

<p>But just because a scientist cannot repeat a particular event doesn’t mean it didn’t happen.  Both natural history and human history contain unique events that only happened once.  As we peer into the past, the difficulty of discerning fact from fiction inspires us to further investigate the mysteries that surround us.
</p>

<h3>Conclusion</h3>

<p>David Lack’s book <em>Evolutionary Theory and Christian Belief</em> was quite insightful, but his enduring achievements took place in evolutionary biology, a place where many Christians are afraid to tread.  While it is significant that he himself found no contradiction between his faith and his science, perhaps the greatest testament to the compatibility between Christian faith and evolution is the life he led as a believer in both.  As we saw in Ernst Mayr’s candid praise, Lack reflected the light of Christ through both his personal and his professional relationships.</p>

<p>Today, many voices in our culture still insist that evolution is incompatible with a sincere faith in Jesus, but a careful look at history demonstrates otherwise. In the future, perhaps more people of faith will have confidence to study biology knowing that one of the most iconic symbols of evolution—the Galapagos finches—owe their fame in large part to a devout Christian named David Lack.</p>

        <guid>http://biologos.org/blog/gracious&#45;dialogue?utm_source=RSS_Feed&amp;utm_medium=RSS&amp;utm_campaign=RSS_Syndication</guid>
        <description>Our desire to engage in gracious dialogue with fellow believers who reject biological evolution has been receiving increased attention in both the Christian and secular press.  More importantly, we are being joined in this reconciling project by our brothers and sisters in Christ who have often been defined primarily as our “opponents”.</description>
        <content:encoded><![CDATA[<p>There are two main reasons why it is critically important that science & faith conversations between Christians be conducted with grace and humility.  First, as all of us see “through a glass darkly,” we need the insights of the entire Christian community (from scientists, to theologians, to Biblical scholars, to pastors to poets) in order to achieve the best understanding of the world God called us to cultivate and rule as his regents. No one discipline or perspective is sufficient in itself, whether focused on God’s Word or God’s world.</p>

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

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

<img src="http://biologos.org/uploads/static-content/CT_Cover.png" alt="" height="189" width="139" style="float:right;margin:0px 0px 0px 10px;" />

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

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

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

        <description>In this series, Davis identifies core tenets or assumptions about the view of concordism, beginning with propositions about the Bible before concluding with a short historical commentary.</description>
        <content:encoded><![CDATA[<p>The word “concordism” is found in neither <a href="http://www.merriam-webster.com">Merriam Webster</a> nor the <em>Oxford English Dictionary</em>, yet it’s often used in contemporary works dealing with origins. Derived from the word “concord,” meaning a state of harmony, “concordism” has been used sparingly in English for more than a century. However, its prominence today comes from a thoroughly scholarly book written shortly after World War Two by the late Baptist theologian <a href="http://en.wikipedia.org/wiki/Bernard_Ramm">Bernard Ramm</a>, <em>The Christian View of Science and Scripture</em> (1954). As Ramm defined it, concordism “seeks a harmony of the geologic record and the days of Genesis,” by which he really meant an old-earth creationist approach. </p>

<p>I am using the term in the same sense. Like Ramm, I don’t regard theistic evolution as a concordist view, even though some TE proponents like to say that evolution can be “harmonized” with Genesis. At the same time, Ramm completely rejected Price’s recent creation and Flood Geology, and he obviously did not consider that view to be a type of concordism either. Why not? On first glance, the YEC view might seem to fall within Ramm’s definition of concordism, and the authors of <a href="http://biologos.org/resources/books/origins">one of the books</a> recommended in the first column in this series classify it as a type of concordism. However, the harmony sought by YEC proponents comes at the cost of entirely rejecting the <em>standard</em> geologic record, which they replace with Flood Geology. That isn’t what Ramm had in mind by seeking a “harmony.”</p>

<p>Often the concordist view is called “progressive creation,” another term that Ramm used with much approval: “<em>We believe that the fundamental pattern of creation is progressive creation</em>,” he wrote prominently in italics. Indeed, it is sometimes assumed that Ramm invented both terms, “concordism” and “progressive creation,” when in fact he did no such thing. If anything, the latter term is even older than the former, having been used to refer to an OEC interpretation of natural history for about two centuries. The first American author to use it may have been <a href="http://en.wikipedia.org/wiki/Benjamin_Silliman">Benjamin Silliman</a>, an evangelical who was appointed the first professor of natural history at Yale by another evangelical, Yale’s president <a href="http://college.cengage.com/english/lauter/heath/4e/students/author_pages/eighteenth/dwight_ti.html">Timothy Dwight</a>. Silliman was the single most influential figure in American science during the nineteenth century. In his <em>Outline of the Course of Geological Lectures Given in Yale College</em> (1829), Silliman spoke of “the progressive creation, life, death and sepulture [fossilization], of animals and plants.” On another occasion he noted how the Bible describes “a successive creation of plants and animals, ending with man,” and that geology “proves this history to be true.”</p>

<p>Clearly, then, the concordist or progressive creationist view has been around for a long time. Let’s examine its main components.</p>

<h3>Core Tenets or Assumptions of Concordism</h3>

<p><strong>(1)	The Bible and science (mainly geology and astronomy) are <em>BOTH</em> reliable sources of knowledge about the origin of the earth and the universe. God has written two “books” for our instruction, the book of nature and the book of scripture. Since God is the author of both “books,” they must agree when properly interpreted.</strong></p>

<p>If this strikes you as worded deliberately to sound like <a href="http://biologos.org/blog/galileo-and-other-good-books-about-science-and-the-bible">Galileo</a>, you’re right—but only because so many proponents of the concordist view also have Galileo very much in their minds. The basic scheme is neatly depicted in this diagram:</p>

<img src="http://biologos.org/uploads/static-content/z-levels.gif" alt="" height="325" width="358" style="display:block; margin-left:auto;margin-right:auto;" />

<p>Recall Galileo’s belief that the book of nature, written in the divine and unambiguous language of mathematics, should be used to help interpret the book of scripture, written in the richer but more ambiguous language spoken by the ordinary persons for whom its vital message of salvation was intended. When they accept the evidence for an ancient earth, Silliman and many other evangelical scholars right down to our own day believe they have merely applied Galileo’s logic to a different set of biblical texts. </p>

<p><strong>(2)	Scientific evidence, when properly interpreted, is consistent with the Bible, when properly interpreted. </strong></p>

<p>Galileo again: because both “books” are written by the same Author, they must agree. As he said in his <a href="http://www.disf.org/en/documentation/03-Galileo_Cristina.asp">Letter to Christina</a>, “the holy Bible can never speak untruth—whenever its true meaning is understood. But I believe nobody will deny that it is often very abstruse, and may say things which are quite different from what its bare words signify. Hence in expounding the Bible if one were always to confine oneself to the unadorned grammatical meaning, one might fall into error.” </p>

<p>What about those who interpret the book of nature? Can they ever be mistaken? Should they ever yield to those who interpret the book of scripture? Evolution was not the source of Galileo’s concerns, but concordists today would give the nod to scripture mainly when it comes to evolution—especially human evolution. Regardless of how much evolution they accept for other organisms, concordists hold strongly to the separate creation of Adam and Eve as the first human beings. They believe that Genesis 1 was intended to be at least broadly historical, even though it does not provide detailed scientific information.</p>

<p>Mainstream conclusions in geology and cosmology, however, are almost always accepted; indeed, <a href="http://www.reasons.org/articles/big-bang---the-bible-taught-it-first">Hugh Ross</a> and some other <a href="http://www.bibleandscience.com/science/images/showmegod.jpg">OECs</a> not only accept the “big bang” theory of the universe, they actively promote it as central to Christian apologetics, because it presents us with a universe that is not eternal and that appears to be exquisitely designed as a home for living creatures, including ourselves. </p>

<p><strong>(3) The Bible does <em>NOT</em> tell us the age of the earth.</strong></p>

<p>Two main concordist approaches to resolving the tension between Genesis and scientific dating of the earth have been popular since the mid-nineteenth century: the “day-age theory,” which still has numerous advocates (including Ross), and the “gap theory,” which is now nearly extinct. One hundred years ago, however, the gap theory was probably the more popular option among conservative Protestants, and it remained so until the 1960s and 1970s, when the rapid spread of Scientific Creationism all but relegated the gap view to the dust bin.</p>

<h4>The Gap Theory</h4>

<img src="http://biologos.org/uploads/static-content/timeline.gif" alt="" height="230" width="568" style="display:block; margin-left:auto;margin-right:auto;"  />

<p>The gap theory posits a “gap” of untold length between “the beginning” of Genesis 1:1 and the first “day” of creation, starting with Genesis 1:3; the formless void of Gen 1:2 corresponds to this “gap.” Verse 1 refers to the original creation of the earth and the universe “in the beginning,” not to world as we now find it. The fossils represent creatures that populated the original creation. <em>Current</em> living creatures come from a second creation, after the “gap,” when God made them in six literal days, culminating in the creation of Adam and Eve just a few thousand years ago.</p>

<p>Although the creation of humanity matches the traditional biblical chronology—a major reason for the popularity of the gap theory in its heyday—the original creation cannot be dated from the Bible. Whether it happened 100 million years ago (as scientists thought around 1900) or billions of years ago (as scientists thought for much of the twentieth century), does not matter one bit to the Bible. Geologists can say whatever they wish about the age of the earth. The <a href="http://en.wikipedia.org/wiki/Scofield_Reference_Bible">Scofield Reference Bible</a>, originally published by Oxford University Press in 1909, taught the gap theory to generations of conservative Protestants in the English speaking world. The headings alone indicate Scofield’s endorsement of the gap theory, and he waited no longer than the second footnote to spell it out: “The first creative act refers to the dateless past, and gives scope for all the geologic ages.” (NOTE: the date “B.C. 4004" in the middle column refers to the start of the six days, not to “the beginning.” I’ll elaborate on that date in part two of this column.)</p>
 
<img src="http://biologos.org/uploads/static-content/scofield_page.jpg" alt="" height="507" width="570" style="display:block; margin-left:auto;margin-right:auto;" />

<p>As Scofield’s third note shows, the gap theory was usually placed within an elaborate theological structure about the fall of Satan and the angels, based on certain prophetic texts (see below). A full discussion would take us far afield, but something should be said about how gap theorists interpret Genesis 1:2, the crucial verse for their model. Scofield sticks with the King James Version, “the earth was without form, and void,” doing the exegetical work in his notes, but others like to <a href="http://www.bibleword.org/genesis1.html">render it</a> as, “the earth <strong><em>became</em></strong> a waste place,”, drawing out the implication (in their view) that God destroyed the original creation, laying waste to it in an act of judgment, leaving us with fossils of the pre-Adamic world. </p>

<img src="http://biologos.org/uploads/static-content/gap_image.gif" alt="" height="468" width="458" style="display:block; margin-left:auto;margin-right:auto;" />

<p>In some versions of the gap view, the original creation included pre-Adamite people—that is, humans who were not descended from Adam and Eve. This idea that took many forms, some with racist overtones. Perhaps this strikes you as a bit surprising, but in the mid-nineteenth century it was a commonplace conception among Protestants, and not <a href="http://www.newadvent.org/cathen/12370a.htm">unknown to Catholics either</a>. A prominent example would be <em><a href="http://archive.org/details/preadamiteearthc187000harr">The Pre-Adamite Earth: A Contribution to Theological Science</a></em> (1846), a very popular book by the English Congregational minister John Harris. Historian David Livingstone has written the definitive history of this fascinating idea. For more, see <a href="http://rorotoko.com/interview/20090206_livingstone_david_adam_ancestors_race_religion_politics_human_orig/?page=1">this interview</a>, but there is no substitute for reading the book itself! Let me make an invitation: who wants to borrow a copy and provide their own commentary here? </p>

<p>In all versions of the gap theory, however, fossils are vestiges of the pre-Adamic world, produced when it was destroyed; they are not a record of evolutionary history. All modern animals and many plants were created recently, in six literal days. Despite what YECs often say, there is just no way to see the gap theory as an “evolutionist” interpretation of Genesis!</p>

<h4>The "Day-Age" Theory</h4>
<p>The day-age theory takes the “days” in Genesis 1 as periods of indefinite length, such that neither the age of the earth nor the duration of any particular period in creation history can be determined from the Bible. The basis for this view is that the Hebrew word “yom” (day) can also mean an indefinite period of time. According to Hugh Ross, the leading advocate of progressive creation today, if the Hebrews had wanted to refer to a long period of indefinite length, they would have used the word “yom.” Thus, he claims to be giving a <em>literal</em> interpretation when he upholds the day-age view.</p>

<p>Numerous varieties of the day-age view have been proposed since the eighteenth century, too many to review here. They all teach that the major kinds of plants and animals were created separately, over the eons of earth history; the fossil record shows reliably which came earlier and which came later. Thus, the creation was accomplished “progressively,” as Silliman held in 1829 and Ross holds today. Ross thinks God performed <em>millions</em> of acts of special creation, but concordists differ substantially among themselves on the magnitude of the number for this.</p>

<p>Concordists mostly agree, however, that the first true humans were Adam and Eve, and that they were created <em>ex nihilo</em>—but, how recently were they created? Can the biblical 6,000 years be stretched far enough to encompass fossils of modern humans (<em>homo sapiens sapiens</em>) dating back perhaps to nearly 200,000 years? Can the biblical picture of Adam’s children living amidst cities and agriculture be reconciled with extensive evidence of humans who lived long before either existed? I’m no anthropologist, but anyone can see the relevance of such questions for this position. </p>

<p><strong>(4) The Flood was a real historical event, but it was not responsible for producing the fossils; rather, fossils are relics of organisms that were mainly here before humans.</strong></p>

<p>The last of the four basic assumptions shared by concordists is that they reject Flood Geology and accept the <a href="http://ebeltz.net/firstfam/geocolum.html">standard geologic column</a>. <a href="http://www.reasons.org/articles/exploring-the-extent-of-the-flood-part-one">Hugh Ross</a> and some others believe that the flood was <strong><em>geographically localized</em></strong>, covering part of the ancient Near East but not the whole globe. This is called the “local flood” view. Biblical scholar Paul Seely <a href="http://biologos.org/blog/series/the-flood-not-global-barely-local-mostly-theological">briefly assesses this view</a> in light of current knowledge here, but a full discussion of the issues goes well beyond of the scope of this online course. Anyone with appropriate expertise is invited to place comments below. The main point is that the flood has no <strong><em>geological</em></strong> significance for concordists, whether or not it was geographically “local.” </p>

<h3>Looking Ahead</h3>
<p>Our look at concordism concludes on July 3 with some conclusions about the OEC view and further historical comments. I’ll pay attention to your comments in the meantime.</p><br> </br>

        <description>This BioLogos videocast addresses the idea of randomness as a part of natural selection, and whether it challenges the possibility of God using the evolutionary process as a means of creation.</description>
        <content:encoded><![CDATA[<p>Today we present the fourth entry in our on-going BioLogos videocast series. So far we have looked at the fossil record and genetic evidence for evolution, as well as speciation and macroevolution. The latest entry addresses the idea of randomness as a part of natural selection, and whether it raises questions about the possibility of God using the evolutionary process as a means of creation. The script was written by biology student Joy Walters, with help from BioLogos president Darrel Falk.</p>

<p>For more, be sure to read Randall Pruim's recent series <a href="http://biologos.org/blog/series/randomness-and-gods-governance">Randomness and God’s Governance</a>, Kathryn Applegate's post <a href="http://biologos.org/blog/thats-random-a-look-at-viral-self-assembly2">That's Random: A Look at Viral Self-Assembly</a>, and our FAQ <a href="http://biologos.org/questions/chance-and-god">How Do Randomness and Chance Align with Belief in God's Sovereignty and Purpose?</a>.</p>

<h3>Author's Note</h3>

<p>I am so thankful that I grew up in a Christian environment, which both kindled and nurtured my relationship with Jesus Christ. The Biblical instruction I received from my parents, pastors, and teachers has been invaluable as I walk out my love for the Lord from day to day. However, there was one specific topic growing up which was not fully addressed, namely evolutionary theory. </p>

<p>Coming from a conservative Christian background, evolution was given little or no thought because of its seeming contradiction to the creation story in Genesis. To me, evolution meant a monkey became a human, and as far as I knew, I had never seen that happen! So, of course, it appeared too improbable to hold any truth. When it was discussed, an inadequate picture of its ideas was often painted, which caused immediate suspicion and rejection of the theory. I don’t think this was intentional, but most Christians have never learned an unbiased, in-depth theory of evolution that is completely detached from societal agendas and philosophical conclusions. Therefore, their explanations of the theory are often misinformed. </p>

<p>My senior year of high school, I took AP Biology, and finally learned the scientific reasoning supporting this theory. I was surprised by how logical and obvious the mechanisms of change (such as mutations, natural selection, genetic drift, and so on) were that gave rise to new species. My subsequent response was, “No wonder people believe evolution occurred.” At that point, I was convinced that microevolution (evolution within a species) existed, but I was still questioning macroevolution.  </p>

<p>Now, being at Point Loma Nazarene University as an undergrad in the Biology-Chemistry major and a year-round, student intern at BioLogos, my understanding of evolution has expanded enormously. I have enjoyed critically thinking through the evidence for evolution and reading articles that tackle difficult issues at the interface of science and Christian faith. Ultimately, I know that God has created all things, but the processes he used surpass my small understanding. </p>

<p>My personal wrestling with evolution and quest for truth has led to times of prayer and studying God’s Word, which has deepened my love for him in ways I cannot express. The first chapters of Genesis, in particular, have come alive. My whole life, the creation story was a straightforward list of facts about the creation of the world; I never searched further. I didn’t even perceive the truths Genesis declared over my very identity and God’s character. The more I study his Word and handiwork, I glimpse the awesomeness and majesty of the Creator, who loves me much more than I know. There is still so much to learn, but I am confident that he will lead me into all truth as I seek him out.</p>

<p>I desire to give others the opportunity to see evolution accurately and to distinguish it from the traditional, philosophical, and personal conclusions that too often cloud the scientific theory. I believe these conclusions alienate Christians from evolution more than the scientific theory itself. Ultimately, I do not mean to convince someone about evolution, but simply to give them the freedom to understand it. </p>

<p>Therefore, my goal for this podcast is two-fold:</p>

<ul><li>First, to offer a new perspective on randomness within natural processes that removes its negative connotations (especially as it relates to evolution).</li>
<li>Second, to expose why evolution is powerless to support conclusions beyond the physical realm.</li></ul>

<p>This will hopefully encourage others to study evolutionary theory and draw their own conclusions about its meaning in the framework of their faith.</p>]]></content:encoded>

        <description>In this three&#45;part series from Pruim’s chapter in the book Delight in Creation: Scientists Share Their Work with the Church, mathematician Randall Pruim explains what scientists and mathematicians mean when they speak of something being “random”. He also addresses God&apos;s use of apparent randomness in creation as a part of his sovereign rule.</description>
        <content:encoded><![CDATA[<p>I’ve enjoyed playing games as long as I can remember. Among my earliest memories are playing <em>Candy Land</em>, <em>Chutes and Ladders,</em> <em>Don’t Break the Ice</em>, and <em>Don’t Spill the Beans</em>. When I was a child, whenever someone did not know what to get me for a birthday or Christmas present, a game was always a good choice. Today, in the back room of our house, we have a closet filled with games that my children and I have accumulated over the years. The rest of our games are either in a closet upstairs or in one of several large boxes in the attic. Periodically we rotate the location of the games for variety.</p>

<p>Many of the games I enjoyed playing involve a combination of strategy and randomness: card games of various sorts, backgammon, and board games like <em>Monopoly</em> and <em>Parcheesi</em>. Some games that rely exclusively on chance (like <em>War</em> and <em>Candy Land</em>) or too heavily on chance (like <em>Sorry</em>) quickly became uninteresting to me. In fact, for <em>Sorry</em>, <em>War</em>, and several other games, I introduced additional rules to change the balance of strategy and luck—for example, by allowing each player to hold a hand of cards rather than merely flip a card and follow its bidding.</p>

<p>When my children were young, I played many games with them, especially those involving some amount of chance. I always play to win, so games of pure strategy like chess gave me too great an advantage—at least when they were still young. I still remember the first time I played the German game <em>Mitternachtspartie</em> with my children and some of their cousins. The game uses a die on which the number 5 has been replaced with the image of Hugo the ghost. Each player rolls the die and moves one of his figures the specified number of squares, unless Hugo is rolled, in which case Hugo moves instead. </p>

<p>I quickly worked out the expected distance Hugo would move for each of my turns and the expected number of squares I would get to move my own figures each turn. Using that information, I could strategically place my figures in the opening portion of the game. I fully expected to win this first game, since my young children were going to have to learn from experience what I already knew by the mathematics of probability. I lost—badly. As it turned out, the die had two Hugos on it. So compared to my expectations, Hugo moved twice as often, and my figures moved slightly less far. That combination turned the carefully calculated positioning of my figures into a disaster.</p>

<h3>From Fun and Games to Science</h3>

<p>I still enjoy playing games, including games that involve chance. But these days I encounter randomness even more often in my profession. I was trained as a mathematician and now work at the intersection of mathematics, statistics, and computer science.  Like many scientists, I use randomness on a daily basis as part of our toolkit for modeling and investigating all sorts of phenomena. Models known as stochastic models, which explicitly incorporate random components, often via simulation in computer software, are used to model everything from diffusion to genetics to quantum mechanics. Insurance companies and financial institutions use stochastic models to manage risk. If we include all the applications of statistics, then almost no area of science is untouched by the use of randomness.</p>

<p>Most of the time, scientists and game players alike don’t devote much thought to just what makes randomness tick. But they both know that the better they understand the probabilities, the more successful they are. Nevertheless, if you ask many of them what it means for something to be random, they may struggle to put it into words. I won’t try to give a precise definition either, but it is important that we have some idea what we are talking about, so let’s consider one of the prototypical examples of randomness: the tossing of a fair coin.</p>

<p>If I flip a coin, the result could be heads or tails. Until I flip the coin, I don’t know which it will be. In this sense, the coin toss is unpredictable. If the coin is fair, each result is equally likely, so while I cannot say in advance whether a particular result will be heads or tails, I can say something about a large number of flips: approximately half should be heads and the other half tails.</p>

<p>A little mathematics even allows me to determine a range around 50% in which the percentage will almost surely lie. For example, if I flip a fair coin 1,000 times, the percentage of heads will most likely be between 45% and 55% (where “most likely” means a 99% chance). If the percentage of heads lies outside this range—especially if it is quite far outside this range—I am going to be suspicious that the coin flipping process is not fair. That’s one of the key ideas in statistics: not only can we calculate the frequency with which an event occurs, but we can compare data to a stochastic model to see if they are compatible or incompatible.</p>

<p>There are several interesting things we can learn by considering a coin toss. First, probability calculations rely on assumptions. If the assumptions are incorrect, then the probability calculations will also be incorrect. For example, if the coin is biased (such as one that is heads 60% of the time), but we assume it is fair, then the probability calculations given above will be wrong. Of course, if the assumptions are not too far from correct, the results may still be sufficiently accurate for scientific conclusions. If we have an appropriate way to collect data, then we can test our assumptions by comparing data to projections made based on the assumptions.</p>

<p>Second, “random” does not imply “equally likely.” A fair coin should have equal probabilities of heads or tails, but a biased coin is no less random. It’s just different. It is not as simple to handle arithmetically as a situation in which all outcomes are equally likely, but it is not otherwise special. It is a common mistake to assume random events are equally likely when they are not (or when that assumption is not justified).</p>

<p>Third, randomness is about the process. It is a fun experiment to flip a penny 100 times, then spin a penny 100 times and record the side that is showing when it finally tips over, then to stand the penny on end (this takes a steady hand and a little practice) and record which side is showing after pounding the table. These are three different processes, and they do not yield the same results.</p>

<p>Fourth, random processes produce patterns. I sometimes ask my students to mentally flip a coin and record the results as a sequence of letters (e.g., “HTTHHTHT”). Then I have them actually flip a coin and record the results. If the sequences are long enough, I can almost always tell them which is which. The sequences imagined by the students tend to have too few runs of consecutive heads or tails. The sequences based on real coin flips usually include several heads in a row. People not familiar with randomness are often surprised at the patterns that result and assume that the process must not have been random when they perceive a pattern. Our eyes and minds are drawn to similarities and patterns—even those that are produced purely randomly. This can lead us to draw false conclusions from coincidences of all sorts. </p>

<img src="http://biologos.org/uploads/static-content/Pruim_Randomness_1_1.png" alt="" height="528" width="500"  />

<p>Consider the image in Figure 1. It was constructed using a computer to randomly throw 300 darts at a square board. Every position on the board was equally likely to be hit by a dart. This does not, however, mean that the dots are evenly spaced. There are 100 smaller squares. The average is three dots per square. But your eye is likely drawn to some clusters and voids. My eye also catches a graceful downward swoop in the lower part of the upper left quarter. All of this is exactly what we should expect from this random process. If we repeated this experiment, we should expect similar results. Several of the smaller squares would be empty and some others would have two or three times the average number of dots, but these clusters and voids would appear in different places.</p>

<img src="http://biologos.org/uploads/static-content/Pruim_Randomness_1_2.png" alt="" height="757" width="476"  />

<p>Finally, randomness can be used to produce patterns intentionally. Consider the two pictures in Figure 2. You may think the two pictures are identical, but they are not. However, they were each constructed using the same random process: 

<ol><li>Start at the lower left corner of the big triangle. </li>
<li>Randomly choose one of the three corners of the big triangle.</li>
<li>Move half way to that corner, placing a dot at the new location. </li> 
<li>Repeat steps 2 and 3, 50,000 times.</li></ol>

<p>The first few steps of this process for each image are illustrated in Figure 3. Although the final images look very similar, the route taken to get there is very different. In fact, the only point the two images have in common is the starting point. As the creator of the program that generated these images, I knew full well that the result would resemble a fractal image known to mathematicians as Sierpinski’s Triangle, even though I did not know or exercise any control over how the individual points would be selected.</p>

<img src="http://biologos.org/uploads/static-content/Pruim_Randomness_1_3.png" alt="" height="816" width="487"  />

<p>Despite our familiarity with children’s games and the importance of stochastic models throughout the sciences, many Christians have a reaction to randomness that falls somewhere between uneasy and antagonistic. And yet, those same Christians may well watch the evening news to learn about public opinion polls forecasting upcoming elections, take prescription drugs approved by the FDA based on statistics found in clinical trials, obtain electrical power from a nuclear power plant that uses random fission reactions, and insure their cars with companies that rely on stochastic models to set the rates. The foundation of each of these activities is a thorough understanding of randomness that begins with the simple description above.</p>

<p>So where does the uneasiness come from? Likely it comes from the feeling that taking randomness seriously means not taking God seriously. Or put more strongly, it comes from a fear that believing in randomness means not believing in God.  Next week we’ll address that problem by asking the question, “Could God use randomness to achieve his purposes?”</p><br></br>

        <description>It should not be surprising that John Cage asked the stuff he used to make paintings to take part in the process—to contribute its own identity to the intentional, purposeful, and determined work of creating “based on chance.”</description>
        <content:encoded><![CDATA[<p>Mathematician Randall Pruim ended the <a href="http://biologos.org/blog/randomness-and-gods-governance-part-1">first installment </a>of his series on randomness and God’s governance by noting that “many Christians have a reaction to randomness that falls somewhere between uneasy and antagonistic” because they think that “taking randomness seriously means not taking God seriously.” While Pruim will continue to explore randomness as a mathematical concept, I’d like to approach the counterintuitive idea that God would “intentionally” use chance processes in his creative work by looking at the practice of John Cage, an artist whose music and visual art was built around the use of chance. One set of Cage’s visual works in particular—the New River Watercolor series from 1988—can help us think about how “allowing” for chance is actually an opportunity for positive and intimate engagement with the created world. I’d like to offer this instance of human making using randomness as an analogy for thinking about how God uses randomness in his own making, and suggest that “chance” is always both limited and guided by the intentions of the creator.  To do that, though, we need to spend a little time understanding how Cage used chance in his work.  </p>

<p>In the 1950s, Cage began using various methods of “casting lots” to determine how elements of his music would be chosen and arranged—principally the Chinese system of <em>I Ching</em>.  His controversial program was to distance himself from his own creative process, and he explored many additional strategies to transform the role of “creator” into one of “observer.” Most famous of these was his musical composition, “4.33,” which consisted of a pianist sitting at the instrument doing nothing at all for four minutes and thirty-three seconds, while musician and audience listened to the ambient sounds of the concert hall.  Yet contrary to that main thrust of Cage’s work, a description of the activities during the week-long residency at the Mountain Lake Workshop where the New River Watercolor Series were made suggests that choice, constraint, and intention were integral and inescapable tools in putting randomness to work for creative ends.</p>

<p>Here’s art historian and theorist Howard Risatti’s description of Cage’s plan of action for the New River Watercolors, from the <a href="http://www.raykass.com/html/Cage/cage01.html">website</a> 
 of artist Ray Kass, who runs the Mountain Lake program and was Cage’s collaborator for his work there:</p>

<blockquote><p>Following upon [a previous (1983) Mountain Lake workshop] “painting experiment,” stones collected from the New River were sorted into three groups according to size, which were separately numbered; numerous and varied brushes were divided into two separately numbered groups; likewise, feathers to paint with, colors and washes, and papers were also divided and numbered. In this way, chance procedures using pages of random numbers that were now generated by a computer program could be used to determine the specific materials utilized for each painting (e.g., which painting instruments, what type of paper and which colors, how many washes, which stones to paint around, where to locate the stones on the paper).</p>
</blockquote>

<p>While this list enumerates all the specific variables that Cage and his team submitted to chance, there was an incredible level of personal engagement with the materials: Cage didn’t just show us drawings of where the<em> I Ching</em> said the rocks ought to be, he (or his assistants) placed them on the paper and used them as guides to paint around. Large custom brushes were constructed to lay on washes of color, and even the paints were hand mixed, combined, and diluted according to his desires.</p>

<img src="http://biologos.org/uploads/static-content/Cage_2txt.jpg" alt="" height="604" width="250" style="float:right;margin:0px 0px 0px 10px;"  />

<p>Cage’s use of chance, then, was not a “hands off” process, but neither was it a matter of total control: Cage selected processes to create a space of play between himself and the materials he used: the feather between himself and the paper, for instance, introduced variability of resistance and spring, its ability to hold paint, the width of the line. All of these things were elements of material ‘freedom,’ areas in which Cage asked the stuff he used to make the paintings to take part in the process—to contribute its own identity to the intentional, purposeful, and determined work of creating “based on chance.”  This should not be surprising, as all art, all creation that we can observe, happens as a dialectic between materials and the creator, and such engagement and interaction in no way lessons the purpose of making, the end in sight.</p>

<p>Kass’ book <em>The Sight of Silence: John Cage’s Complete Watercolors</em>, gives a much more complete account of the tools, processes, and interpersonal reactions between Cage, Kass, and the team of student assistants who helped at almost every stage of the creation of the works. The book goes to great length to honor Cage’s ideal of being present in but not controlling the outcomes (not least by nearly always putting words like “choice” in quotation marks), but the description of his process makes the centrality of Cage’s personal aesthetic and artistic motives inescapable, even more than his physical engagement.  What comes through perhaps even more than the way Cage intended to allow chance to ‘guide the creative process’ is that way Cage, himself, not only set the parameters of the chance he allowed into the system, not only engaged directly with the materials during the process, but also exercised judgment over the results, both in process and at the end:</p>


<blockquote><p>“Cage decided he didn’t want the images of the stones to overlap or go off the sides of the paper. To guarantee this restriction, he created conditions and rules to limit their possible placements.” (p. 51)</p>
</blockquote>
<blockquote><p>“For this single painting [Series IV, #1, pictured above] Cage chose to confine the images of the rocks to a lower area of the paper that represented the proportion of the “golden rectangle. . .” (p. 57)</p>
</blockquote>
<blockquote><p>“While “choice” established much of the work’s nature, “chance” highlighted the intrinsic nature of the materials to reveal a refreshing presence.” (p. 59)</p>
</blockquote>
<blockquote><p>“[H]e initially decided to remove [the first painting of Series III] from the group, and then, liking it more, changed his mind and returned it to the group that would be signed.” (p. 56)</p></blockquote>

<p>This last note is particularly interesting in that it highlights the fact that Cage was claiming these paintings, naming himself as their author, and was attentive to which ones he approved of enough to call his own. There is no way around the fact that Cage was subjectively as well as objectively the maker of these works: the author of the procedures by which they came to be, but well as the judge (and sometimes redeemer) of the results.  For Cage, randomness was a tool, no different than the brushes or rocks or paints is that its specific parameters were chosen at the outset, and always used within the context of his over-arching vision.  Perhaps we may likewise think of God’s use of chance—constrained by and tuned to the material conditions he established at the birth of the cosmos—as a way to both engage with and allow freedom for the creation itself.</p>

<p>With any work of art it is reasonable to ask, “Is it beautiful?” or more tellingly,  “Would I hang this on my wall?”  Seeing Cage’s watercolors for first time without any knowledge of the process or the relative fame of Cage himself, some might be intrigued by the structure of the work (the proportions of the golden rectangle, the overlapping stone shapes, the colors of the paint) while others would be completely uninterested, perhaps even after hearing about how they were made and seeing them in the context of the rest of the New River Watercolor series.  But if you had been there in the shop as an assistant, or even observer, if you had been party to the relationships that developed even over the few days Cage spent at the Mountain Lake Workshop, your sense of the beauty of these paintings (and perhaps even scraps of paper Cage used to try out brushes or washes), would take on a different meaning, in much the way we treasure the crayon drawings of our children not because they are spectacular art, but because they are tokens of our relationship.  </p>

<p>I make that observation to emphasize one other aspect of Cage’s creative process: that Cage was the instigator first and foremost of <em>relationships</em> of creation.  His process created not only paintings but the fellowship that developed as the work was being done.  That social, interpersonal dimension is what gives the objects a depth of meaning beyond their material composition, and suggests the particular roles humanity has been given by God.  One role is to join into the creative process as lesser, but not unimportant co-creators with him; the other is to observe, recognize and celebrate his activity in the world. Where some will see randomness as evidence of an absent God, our knowledge of this most personal and participatory aspect of creation points us to the God who is with us.</p>

<p>With God’s creation as with human art, we may (or may not) marvel at any one particular “work,” or even think the specifics of how it was made are interesting or attractive; but knowledge of and fellowship with the artist transforms our appreciation of the process as well as its results.   When we know the maker, we come to recognize and treasure even the most “random” bits of his handiwork, and name them as his, nonetheless.</p>

        <description>Perusing the writings of atheistic scientists and philosophers like Daniel Dennett, one could easily get the impression that arriving at a simpler explanation for something equates to a revelation that things are “lower, cruder, and more trivial.”</description>
        <content:encoded><![CDATA[<p>In his essay <a href="http://www.firstthings.com/article/2010/09/fearful-symmetries" target="_blank"><em>Fearful Symmetries</em></a>, published in the October 2010 issue of the journal <em>First Things</em>, physicist Stephen Barr offered a critique of the modern tendency to make the investigative strategy of reductionism into a “metaphysical prejudice.”  It is a mistake, he says, to take the extraordinary success of the scientific practice of looking at things in smaller and simpler parts as proof that “the further we push toward a more basic understanding of things, the more we are immersed in meaningless, brutish bits of matter.”</p>

<p>Perusing the writings of atheistic scientists and philosophers like Daniel Dennett, one could easily get the impression that arriving at a simpler explanation for something equates to a revelation that things are “lower, cruder, and more trivial.”  But at the heart of Barr’s critique is the observation that in fundamental physics and advanced mathematics, “simpler” does not mean more chaotic and inchoate, but rather more elegant and beautiful.  Those who hold to a philosophical reductionism “overlook the hidden forces and principles” that govern the processes of cosmic evolution.</p>

<p>Barr’s article lays out the way that the work of scientists and mathematicians exploring the fundamental principles of physics (from Kepler to Einstein to those currently running the Large Hadron Collider in Switzerland) actually suggests “that order does not really emerge from chaos, as we might naively assume; it always emerges from greater and more impressive order already present at a deeper level.”  This excerpt gives his first example, the starting point from which he guides us into strangely beautiful world of particle physics, and towards the discovery that “matter, although mindless itself, is the product of a Mind of infinite profundity and infinite simplicity.”</p>

<h3>Fearful Symmetries</h3>

<blockquote><p>“Let’s start with a simple but instructive example of how order can appear to emerge spontaneously from mere chaos through the operation of natural forces. Imagine a large number of identical marbles rolling around randomly in a shoe box. If the box is tilted, all the marbles will roll down into a corner and arrange themselves into what is called the “hexagonal closest packing” pattern. (This is the same pattern one sees in oranges stacked on a fruit stand or in cells in a beehive.) This orderly structure emerges as the result of blind physical forces and mathematical laws. There is no hand arranging it. Physics requires the marbles to lower their gravitational potential energy as much as possible by squeezing down into the corner, which leads to the geometry of hexagonal packing.</p>

<p>At this point it seems as though order has indeed sprung from mere chaos. To see why this is wrong, however, consider a genuinely chaotic situation: a typical teenager’s bedroom. Imagine a huge jack tilting the bedroom so that everything in it slides into a corner. The result would not be an orderly pattern but instead a jumbled heap of lamps, furniture, books, clothing, and what have you.</p>

<p>Why the difference? Part of the answer is that, unlike the objects in the bedroom, the marbles in the box all have the same size and shape. But there’s more to it. Put a number of spoons of the same size and shape into a box and tilt it, and the result will be a jumbled heap. Marbles differ from spoons because their shape is spherical. When spoons tumble into a corner, they end up pointing every which way, but marbles don’t point every which way, because no matter which way a sphere is turned it looks exactly the same.</p>

<p>These two crucial features of the marbles—having the same shape and having a spherical shape—should be understood as principles of order that are already present in the supposedly chaotic situation before the box was tilted. In fact, the more we reduce to deeper explanations, the higher we go. This is because, in a sense that can be made mathematically precise, the preexisting order inherent in the marbles is greater than the order that emerges after the marbles arrange themselves. This requires some explanation.</p> 

<p>Both the preexisting order and the order that emerges involve symmetry, a concept of central importance in modern physics, as we’ll see. Mathematicians and physicists have a peculiar way of thinking about symmetry: A symmetry is something that is done. For example, if one rotates a square by 90 degrees, it looks the same, so rotating by 90 degrees is said to be a symmetry of the square. So is rotating by 180 degrees, 270 degrees, or a full 360 degrees. A square thus has exactly four symmetries.</p>

<p>Not surprisingly, the hexagonal pattern the marbles form has six symmetries (rotating by any multiple of 60 degrees: 60, 120, 180, 240, 300, and 360 degrees). A sphere, on the other hand, has an infinite number of symmetries—doubly infinite, in fact, since rotating a sphere by any angle about any axis leaves it looking the same. And, what’s more, the symmetries of a sphere include all the symmetries of a hexagon.</p>

<p>If we think this way about symmetry, careful analysis shows that, when marbles arrange themselves into the hexagonal pattern, just six of the infinite number of symmetries in the shape of the marbles are ex-pressed or manifested in their final arrangement. The rest of the symmetries are said, in the jargon of physics, to be spontaneously broken. So, in the simple example of marbles in a tilted box, we can see that symmetry isn’t popping out of nowhere. It is being distilled out of a greater symmetry already present within the spherical shape of the marbles.”</p></blockquote>

<p>In the full essay, Barr gives a richer description of how this most basic kind of symmetry is just one sort of order, and how even this form points to other much more complex kinds of symmetry whose properties may be described only through the tools of complex mathematics. As he says, “the symmetries that characterize the deepest laws of physics are mathematically richer and stranger than the ones we encounter in everyday life.” But even more important than the fact that such mathematical concepts exist and are beautiful, more important even than the way such esoteric mathematical symmetries have suggested imminently practical experimental projects, is the way they point to a universe that is anything but brutish and trivial, though its elegance may be hard to see:</p>
 
<blockquote><p>“It is true that the cosmos was at one point a swirling mass of gas and dust out of which has come the extraordinary complexity of life as we experience it. Yet, at every moment in this process of development, a greater and more impressive order operates within—an order that did not develop but was there from the beginning. In the upper world, mind, thought, and ideas make their appearance as fruit on the topmost branches of an evolutionary tree. Below the surface, we see the taproots of reality, the fundamental laws of physics that shimmer with ideas of profound simplicity.”</p></blockquote>

<p class="intro">Today's video is courtesy of filmmaker Ryan Pettey, director/editor of Satellite Pictures and features physicist Ard Louis.</p>

<p>In today's video, Oxford physicist Ard Louis discusses the famous debate between renowned evolutionary biologists Stephen Jay Gould and Simon Conway Morris. Gould believed (and wrote in his book <em>Wonderful Life</em>) that if the "tape" of evolution were rerun, the chance that anything like human intelligence would emerge is essentially zero. In other words, humanity is here through random accident. Gould pointed to the work of Morris and fellow scientists in their research of the Burgess Shale as evidence for this view.</p>

<p>However, Morris himself disagrees, pointing to what is called evolutionary convergence. As Morris notes, there are numerous examples of identical features evolving multiple times throughout the history of life independently. Morris believes that if the tape of life were replayed, we would see something like humans emerge. A Christian might say, it looks like we were planned.</p>


<p>Some Christians might find Simon Conway Morris' viewpoint, with its implicit teleology, more attractive. Others, perhaps motivated by a high view of providence, may find Gould's emphasis on contingency equally congenial to their faith.  What do you think?</p>]]></content:encoded>

        <title>Mitochondrial Eve, Y&#45;Chromosome Adam, and Reasons to Believe</title>

        <description>When presented with the evidence for human population sizes over our evolutionary history, a common point of confusion for evangelicals is how this evidence fits with Mitochondrial Eve. How can we all come from one woman (and one man) but also come from a large population of 10,000 individuals?</description>
        <content:encoded><![CDATA[<p class="intro">One of the challenges for discussing evolution within evangelical Christian circles is that there is widespread confusion about how evolution actually works. In this (intermittent) series, I discuss aspects of evolution that are commonly misunderstood in the Christian community. In this post, we tackle the issue of why “Mitochondrial Eve” and “Y-chromosome Adam” are not an ancestral couple from whom all humans descend, as claimed by the Old-Earth Creationist organization <em>Reasons to Believe</em>.</p>

<p>It is reasonably well known among evangelical Christians that all living humans trace their mitochondrial DNA back to a single woman (a so-called “mitochondrial Eve”) and that all living males similarly trace their Y-chromosome DNA back to a single male (a so-called “Y-chromosome Adam”).  These individuals are commonly assumed by evangelicals to be the Biblical Adam and Eve, the first humans alive and the progenitors of the entire human race. While most young-earth and old-earth creationist organizations make this claim, perhaps one of the best-known organizations to do so is the old-earth creationist / anti-evolution organization <em>Reasons to Believe</em>, who have produced numerous  articles, podcasts, and even entire books on the subject.</p>

<p>In contrast to this common evangelical understanding, the scientific picture is rather different. Mitochondrial Eve, though the most recent common matrilineal ancestor of all humans, was but one of a large population living about 180,000 years ago. So too for Y-chromosome Adam: he was also a member of a large population, and he lived about 50,000 years ago. As has been discussed several times here at BioLogos, there are multiple lines of evidence that indicate the human population has never been below around 10,000 members at any time in its history: we branched off as a large population to form our own species.</p>

<p>When presented with the evidence for human population sizes over our evolutionary history, a common point of confusion for evangelicals is how this evidence fits with Mitochondrial Eve. How can we all come from one woman (and one man) but also come from a large population of 10,000 individuals? Aren’t these two observations in conflict?</p>

<p>The answer is no, these lines of evidence fit together. Humans do come from a large population, and all present-day humans do inherit mitochondrial and Y-chromosome DNA from specific individuals in the past. The reason for the apparent discrepancy lies in how mitochondrial and Y-chromosome DNA are inherited, as we shall see below.</p>

<p>Mitochondria are organelles responsible for energy conversion, and they contain their own small, circular chromosome that they replicate apart from regular chromosomes in the cell nucleus. Mitochondria are not passed on to progeny through sperm, but only through the egg: as such, mitochondrial DNA is passed on solely through the maternal line. Consider a small pedigree (family tree) below. Circles represent females, males are represented with squares. In this family, one grandmother (the woman at the top right of the pedigree) has passed on her mitochondrial DNA to her sons and daughter, but only her daughter passes it on to the next generation. All individuals who have this grandmother’s mitochondrial DNA are shown in blue:</p>

<p align="center"><img src="http://biologos.org/uploads/static-content/mito_eve_1.jpg" alt="" width="570" height="363"  /></p>

<p>Conversely, if we examine Y-chromosome inheritance in this same family, we would see that (obviously) women cannot pass it on to their children. Here, the red lines show all males who have descended from a grandfather of the family (the male at the top left of the pedigree):</p>
 
<p align="center"><img src="http://biologos.org/uploads/static-content/mito_eve_2.jpg" alt="" width="570" height="355"  /></p>

<p>Now we are ready to examine how these types of DNA are inherited in a larger group, and compare their modes of inheritance with regular chromosomal DNA. While it is not possible to draw out a pedigree for a population of 10,000 individuals, let’s examine a smaller group to see how a specific mitochondrial sequence can “take over” a population of organisms (note that this effect applies to other organisms besides humans that use an XX – XY system of sex chromosomes).</p>

<p>In the family tree below, three mitochondrial DNA variants are present in the first generation (the top row of the pedigree) and a represented with different colors (green, blue and red). Tracing the inheritance of these mitochondrial DNA versions through the family tree shows that all living members of this population (the bottom two rows) have inherited the red version only. The blue and green versions eventually hit a dead end where they were not passed on (either through females who did not have children, or males). As such, all living individuals can trace their mitochondrial DNA back to this group’s “mitochondrial Eve”, the woman at the top right of the tree with the “Mito 3” variant.</p>

<p align="center"><img src="http://biologos.org/uploads/static-content/mito_eve_3.jpg" alt="" width="570" height="391"  /></p>

<p>Let’s now examine Y-chromosome inheritance patterns in the exact same family tree. Suppose there are three Y chromosome variants present in the first generations:</p>
 
<p align="center"><img src="http://biologos.org/uploads/static-content/mito_eve_4.jpg" alt="" width="570" height="386"  /></p>

<p>Here we can see that the current population has inherited its Y-chromosome DNA from one individual as well (variant 1, the red lines) and that the other Y-chromosome variants (blue and green) hit dead ends through males that did not reproduce or men who only had daughters. All living members of the population trace their Y chromosome DNA back to an individual (filled in with yellow) who lived two generations after their most recent matrilineal common ancestor (the woman at the top right).</p>

<p>Now we are ready to examine regular chromosomal inheritance in this same family tree. Genetic variation on chromosomes other than the Y can be passed through either gender without problem, and individuals can have two variants at a time (one on the chromosome inherited from mom, the other on the chromosome inherited from dad). These key differences (compared to how mitochondrial DNA and Y chromosomes are inherited) produce a very different effect. In this same family, numerous variants (represented by the different colors) have been transmitted to the present generation without loss:</p> 
 
<p align="center"><img src="http://biologos.org/uploads/static-content/mito_eve_5.jpg" alt="" width="565" height="371"  /></p>

<p>Notice the middle couple in the first generation in the pedigree. This man’s Y chromosome did not make it to the present day, and similarly his wife’s mitochondrial DNA did not make it either (scroll up to see this if you need to refresh your memory). So, they contributed nothing to the current generation, right? Not at all: both of them have passed on regular chromosomal variation to the present day (traced as blue and black lines).</p>
  
<p>In other words, it would be incorrect to examine this population, determine (correctly) that they share common mitochondrial DNA and Y-chromosome ancestors, and then go on to conclude that these two individuals were an ancestral pair that started this entire family. We know that this group descends from a larger population, because genetic variation in the present population is too large to explain as coming from one pair (there are five colors, or genetic variants in this population, and the max any one pair could carry is four, with two each).</p>

<p>While this example examines a small family, the same principles apply to larger groups: mitochondrial and Y-chromosome lineages, though interesting, cannot be used to estimate population sizes over time. For that type of work, regular chromosomal variation should be examined. Present day human genetic variation indicates that though we all share a common mitochondrial DNA and Y-chromosome source, these individuals came from a population of at least 10,000 individuals, and that they lived over 100,000 years apart. If you are interested in examining the evidence for human population sizes, Darrel Falk and I have discussed it previously.</p>
 
<p>In summary, anti-evolutionary groups, such as <em>Reasons to Believe</em>, that claim that the evidence for Mitochondrial Eve and Y-chromosome Adam supports an ancestral couple for the entire human race are not interpreting the data correctly. They have failed to account for the unique pattern of inheritance these types of DNA have in populations.</p>

<p>In this video, physicist Ard Louis discusses the misconceptions about evolution and what it says about our purpose. A lot of the young earth arguments against evolution, says Louis, can be beneficial to those promoting atheism. According to Louis, both sides are attempting to extract theology from the natural world and wrongly accept the premise that where we come from determines who we are and how we should live. However, that’s not what the Bible tells us; rather, our value comes from God, and God determines who we are and how we should live.</p>

<p>Many understand evolution as a theory underlined by the idea that our existence is purposelessness. But our value and purpose do not come from whether or not we were created by an evolutionary mechanism. Evolution may tell us something about how we were created, but it is not the source of our worth. That worth comes from God.</p>

        <description>In his sermon, Dave Swaim discusses the early chapters of Genesis that seemingly contradict scientific evidence, and he suggests that Christians have simply asked the “wrong questions” about this ancient text, which has led to warfare between the two. In light of this, Swaim wraps up his sermon with the three concluding points that he feels sums up the Biblical truth of creation: there is an all&#45;powerful God, he has a perfect plan, and he has given us his love through Jesus Christ.</description>

<h3>Introduction</h3>
<p>Today BioLogos begins a series that we think ought to have significant impact on evangelical churches far beyond the local congregation in Arlington, Massachusetts where it was first delivered.  A recent   <a href="http://www.christianitytoday.com/ct/2011/june/noadamevenogospel.html/" target="_blank">editorial</a> in Christianity Today stated that many Christians likely face another "Galileo moment."  In that earlier era, finding that the earth moved around the sun--and not the other way around--caused the Church to reorient its understanding of certain scriptural passages.  Today, interconnecting strands of evidence all of which lie at the heart of biology, geology, physics and astronomy require segments of the Church to carefully evaluate its magnificent creation narrative--it needs to be certain it is hearing God's message in the way that God intends for it to be understood.  It is healthy for the conservative wing of Christianity to be carefully examining the genre of the creation narrative.  It has had to do this once before and, it is appropriate to prayerfully seek clarity once again.  Christians are truth-seekers and God's Spirit will guide the process as we sincerely seek that wisdom which is from above.</p>
  
<p>Oratory, at its best, has long been an important key in opening the door to new and dramatically important insights.     Pastor David Swaim of <a href="http://www.highrock.org/" target="_blank">Highrock Church</a> in the Boston suburb of Arlington illustrates this poignantly.  In fact his sermon is so significant, we've asked permission to post it in serial form so that each of us can deeply reflect on his words in a protracted fashion.  We encourage you to let others who are conflicted over this issue know about the series so that they can follow it.   Indeed, we believe It will be a great series for small group discussions--we need to lovingly support each other as we seek God's guidance in coming to understand God's truths.</p>

<p>In this sermon, Swaim discusses our belief in God as creator, or “Maker of heaven and earth”, as the Apostle’s Creeds so poetically states.  To begin, he reminds us that some passages in the Bible, like the parable of the prodigal son, convey deep truths even though they are not historical accounts.  Asking “the wrong questions”—questions that focus on arbitrary details—about such stories can cause us to miss out on their intended message.  In a similar way, he says, it is possible that we might be asking the “wrong questions” about the opening chapters of Genesis.  In recent years, conflict has erupted because a literal reading of Genesis seems to contradict the findings of science.  Swaim suggests, however, that accepting scientific evidence about things like evolution and the age of the earth need not rule out faith in Scripture.</p>

<p class="intro"><em>Introduction written by the BioLogos editorial team.</em></p>

<h3>"Maker of Heaven and Earth" (transcript)</h3>

<p>One of my favorite parables is that of the lost son.  There’s a lot to it. Basically, it’s a story that Jesus told about a young man who insulted his father by demanding his share of the inheritance early, then ran off to spend that money on wild living, and found himself destitute when the money was gone.  In desperation, he returned to his father, asking to work as a servant.  But instead of being angry, his father joyfully embraced his lost son and threw a huge feast to celebrate his return.  It is a great story that Jesus tells to help us understand God’s amazing grace.</p>

<p>How many of you know this story?  Raise your hand, if you would.  Okay.  Now I want to make sure I’m clear…that’s a lot of you…I don’t mean just like, you know it because I just told it to you.  I mean you know it because you’ve heard a sermon on this before, or maybe you’ve read it on your own.  Raise your hand high if that’s true of you.  Wow, still a lot of you.  That’s perfect because I actually have a couple of questions maybe you can help me with.  You see, it says that the father saw the son while he was still a long way off.  Can anybody tell me how far off was the son at that point?  Anybody know that? Because, you know, they didn’t have glasses back then, and the father was really old, so how far could he really see?  It just doesn’t really add up for me.  Can anybody tell me about that?  Nobody?  Okay.  Well I have another question.  Maybe this one’s easier.  What town did that family live in? Does anybody know that?  No?  Nobody?  What town they lived in?  People, this is one of the greatest stories of all time!  This is a story that has changed thousands of lives, including many of yours!  How can you say that you know this story, that you understand this story, if you don’t even understand these basic facts?  Okay, well maybe this is easier.  Speaking of family, the Bible’s into family values, so I want to know—where’s the mother?  Can anybody tell me?  Is this family not intact?  What’s wrong?  Did they get a divorce maybe?  And how come the father ended up with the custody of the sons?  And why did they only have two?  Families back then had much bigger families.  Maybe they just got divorced too early?  But I mean he seems so nice—why do you think she left?  Anybody know these things?  I mean I just don’t get it.  You all tell me you know this story, and yet you don’t understand just these simple things about it. </p>

<p>Obviously, my questions miss the whole point of the story.  There was no mother, or for that matter, no father or son either. This never actually happened.  It’s just a parable.  It’s one of the many marvelous stories that Jesus told in order to help us understand something that was hard to see.  Now does that make it so that this story isn’t true?  No, it is true.  This story communicates some of the most important truths in the universe—about God’s nature, and the way that we relate to him. There are many passages in scripture that promise God’s love, or praise God’s love, or even try to explain God’s love.  But this passage helps us grasp that truth in a way that’s much more effectively communicated than just through direct reporting.  This way helps us feel it.  This event never happened, but it’s one of the truest stories in the world.  And what a shame for someone to dismiss it as irrelevant because it’s not literal history, or miss the point by asking the wrong kinds of questions.</p>

<p>Now I bring this up because just like my questions miss the point of the lost son parable, so, I fear, many of us ask the wrong questions about the beginning of the book of Genesis, which we read from just a few minutes ago.  Not only does this generate needless confusion and division, it also makes us miss the point, miss the life-changing truths that we could see if we asked the right questions.  Right now we’re in a sermon series studying the Apostle’s Creed, an ancient declaration of faith in the God of the Bible.  And today, we’re considering the word “creator.”  So, Genesis seemed like the right place to go.</p>

<p>Like the story of the lost son, most of you know the basic outline: God created the universe in six days and then napped on the seventh (so those of you who nap through my sermons every Sunday, you’re in good company!).  But by adding up all the names of the people mentioned in Genesis, and throughout the rest of the Bible, seventeenth century Bishop Ussher determined that the creation of Adam and Eve, and everything else, happened in 4,004 BC—about 6,000 years ago.  And that’s great.  But you’re probably also aware that this creates some tension with contemporary scientists who suggest a different timeline.  Considering the evidence offered by the size and expansion rate of the universe, plate tectonics, fossil evidence, and genetics, their best guess is that the universe was created by a big bang about 13 billion years ago, the earth appeared about 4.5 billion years ago, and the earliest humans existed about 200,000 years ago.  In the past 300 years, this has become a very heated debate.  Apparently, we need to choose whether we believe in science or in scripture.  At least that’s the claim made by the most strident voices on each side, so the general population seems to have accepted that if you believe in God you can’t believe in evolution, and if you believe in evolution then you can’t believe in God.</p>

<p>This topic arouses passions and anxieties in many people, including some in this room.  No matter what your perspective is, I’m probably going to say something today that you’ll disagree with, and might even make you angry.  There’ll be plenty of time for you to set me straight in the coming weeks.  But for the next half hour, in order to allow the possibility that we might hear something new, or even learn from the Holy Spirit, let’s lay aside our defensiveness so that we can at least consider why we are so attached to whatever ideas we have, and evaluate whether our devotion to one truth may be blinding us to others.  As scientists have discovered more and more evidence supporting the basic evolutionary theory outlined in Darwin’s Origin of Species, Christians have responded in a variety of ways.</p>

<p>Science has been right about so many things, so some Christians have embraced evolution and felt forced to abandon their trust, not only in the truth of Scripture, but also in the God it describes.  Other Christians, including many renowned scientists, have fought back by pointing out the many flaws in evolutionary theory and proposing alternative theories of their own.  These include Young Earth Creation, which asserts that the earth was created in six days six thousand years ago, and offers thoughtful explanations to reconcile the findings of science with the words of Genesis 1.  Old Earth Creationists do the same thing, but contend that each of the days in Genesis could represent an epoch, or a million years, or whatever amount of time, instead of just a 24-hour day.  This is linguistically legitimate—it’s a fine interpretation of the Hebrew word “day” in Genesis—and it recognizes that it’s hard to measure a day before the invention of the sun in day four, anyway.  So, Old Earth Creationism opens up many possibilities to reconcile scientific claims about the age of the earth with a literal interpretation of Genesis.  Theistic Evolution takes further steps to accommodate evolution while still honoring God as the one who created heaven and earth and everything in them through the evolutionary process.  This is attractive because it eliminates the conflict between science and scripture, but it requires a very different way of reading Genesis.  They suggest that, like I did with the parable of the prodigal son earlier, perhaps we’re asking the wrong questions about Genesis so that we’re inventing an unnecessary argument, and even worse, we’re also missing what the first chapters of Genesis really are all about.</p>

<p class="intro">In the next installment, to be posted tomorrow, Pastor Swaim goes on to discuss the Genesis passage in detail.<br /><br />]]></content:encoded>

        <title>Evolution: Is God Just Playing Dice?</title>

        <content:encoded><![CDATA[<p class="intro">This article first appeared on <a href="http://www.huffingtonpost.com/matt-j-rossano/evolution-is-god-just-pla_b_986984.html" target="_blank">The Huffington Post</a>.</p>

<blockquote><p>"Reply the tape a million times ... and I doubt that anything like Homo sapiens would ever evolve again"  (Stephen Jay Gould from "Wonderful Life", 1989 p. 289, Harvard University Press.).</p></blockquote>

<p>With his standard panache, the late Harvard paleontologist Stephen J. Gould argued strenuously that evolution had no inherent directionality. It was a cosmic crapshoot - in no way destined to produce anything complex, self-conscious or human. We are mere accidents; a "tiny twig on an improbable branch of a contingent limb on a fortunate tree" ("Wonderful Life" p. 291). Highly fortunate indeed! Eons ago, a dinosaur-dominated earth held little promise for mammalian ascendancy (let alone primates or humans). Our distant ancestors might have remained little more than scurrying nuisances nipping at the feet of giants if not for a most unlikely calamity - a massive meteor strike which swept away the dinos and forever altered the earth's bio-saga. Who would have guessed? </p>

<p>Evolution's capricious nature seemed to represent a severe stumbling block for the Abrahamaic religious traditions. In their narrative, humans represented the culmination of God's creative work - the very purpose for creation itself. But evolution is an awfully shoddy way of enacting a divine plan. Gould delighted in annoying the faithful by emphasizing this very point:  </p>

<blockquote><p>"Odd arrangements and funny solutions are the proof of evolution - paths that a sensible God would never tread but that a natural process, constrained by history, follows perforce" ("The Panda's Thumb", 1980, pp. 20-1). </p></blockquote>

<p>Theologians, however, were quick to point out that the chance element in evolution was neither new nor necessarily contrary to the Judeo-Christian view of God. Human history was replete with chance; evolution only extended the theme. Moreover, chance allowed for freedom - a virtue high on God's agenda. However theologically sound these retorts may have been, their force was often lost on the average believer. The accidental nature of human existence provided just another reason to reject evolution altogether in order to preserve God's special concern for humanity.  </p>

<p>Gould was a talented science writer, but he overplayed evolution's whimsy. Increasingly, science is showing that the evolutionary process has many built in constraints which limit its possibilities and bias its pathways. Take, for example, the ubiquitous phenomenon of convergence - the tendency for highly diverse species to independently evolve similar adaptive (analogous, not homologous) traits. Most of us are familiar with the saber-toothed tiger, the scourge of our hominin ancestors. Less familiar are a group of South American marsupials called the thylacosmilids who independently evolved similar protruding saber-teeth. Convergence can also be seen in a number of specifically human traits. For example, we share a mode of locomotion, bipedalism, with birds, kangaroos, and some dinos. The lateralized and convoluted structure of our brains can also be found in octopi, this despite the fact that vertebrates and cephalopods diverged from one another over 450 million years ago. </p>

<p>In his book "Life's Solution" (2003, Cambridge Press) Cambridge Palaeobiologist Simon Conway Morris documents scores of examples of convergent evolution from insect body designs to the social systems of dolphins and chimpanzees (both fission-fusion). The important lesson is that there are only a limited number of ways that evolution can solve the adaptive problems posed by the earth's ecosystems. Time and again, evolution stumbles upon the same general design features from which to fashion adaptive traits.</p>

<p>Now add to this the Baldwin effect - an idea originally proposed in 1896 wherein organisms are posited to actively shape their own selective forces. For example, suppose some fairly intelligent primates begin fashioning tools, giving them access to new resources and a competitive advantage over non-tool users. Any genetic predisposition facilitating tool use would also be positively selected. </p>

<p>A severe limitation on Baldwin effects has always been the unpredictability of genetic mutation. For any heritable genetic changes to occur (so the thinking has always been) our tool wielding primate would just have to wait around and hope for a lucky "tool use" mutation to pop up. But maybe not. Two recent books, Jablonka and Lamb's "Evolution in Four Dimensions" (2005 MIT press) and Kirschner and Gerhart's "The Plausibility of Life" (2005, Yale University Press) discuss connections between recent work in genetics and Baldwinian processes. What if the primate's tool use actually raised the probability that a tool-relevant genetic change would take place which could then be passed along to offspring?     </p>

<p>Recent genetic research (in a field called epigenetics) shows that experiences occurring over one's lifetime can produce heritable genetic changes. For example, mice exposed to two weeks of environmental enrichment (more social interaction, activity, novel objects to explore) show evidence of enhanced memory function (not surprising). More surprising is that their offspring also show evidence of enhanced memory even though they were never exposed to environmental enrichment (Journal of Neuroscience, 29, p. 1496). Thus, the increased environmental stimulation created a genetic change in the parents that was then transmitted to offspring. This change appears to involved altered patterns of gene regulation (how genes are turned on and off during development). Similar effects have been noted in humans (see European Journal of Human Genetics, 14, p. 159). </p>

<p>Convergence, epigenetic inheritance, and Baldwin effects are only a few of the mechanisms serving as directional constraints on evolution's pathways. In his review of the various factors affecting the evolutionary process, anthropologist Melvin Konner concludes:</p>

<blockquote><p>"There are no intrinsic <strong>driving</strong> factors in evolution, but there are intrinsic constraints and canalized paths along which either evolution or development may more easily proceed" ("The Evolution of Childhood," Harvard Press, 2010, p. 59, emphasis in original). </p></blockquote>

<p>Of course, none of these constraining factors guarantee our arrival on the evolutionary stage. They do, however, raise the odds that in time a complex, rational, self-aware creature capable of entertaining both scientific and religious ideas might emerge. </p>

<p>The more we understand evolution, the less it seems like neither the bogeyman that creationists fear nor the universal God-dissolving acid some atheists crave.</p>]]></content:encoded>
