More Than One Christian View

Many parents and pastors are wondering what to tell their children about creation and evolution. While Sunday school classes often cover Genesis 1 around kindergarten (with kids coloring pictures of what God created on each day), most curricula do not address science again before kids leave for college. Yet issues of creation and evolution can be addressed in age-appropriate ways throughout Sunday school. Elementary school children already learn about idol worship from other Old Testament stories, so teachers have an opportunity to contrast Genesis 1 with the idol-rich creation stories of other cultures. Middle school students can be given basic tools for considering creation and evolution such as the contrast between the “how” questions answered by their science lessons in school and the “who” and “why” questions answered in Scripture. Middle and high school students can find role models by reading the testimonies of scientist Christians.

Youth need to be encouraged to discuss their questions and doubts, while affirming core beliefs. When asked why they left the faith, scientists often mention that the church was not open to their questions and told them to “just believe.” Churches can demonstrate openness to questions by teaching youth about multiple Christian views on an issue. Students need to hear that some Christians accept the science of evolution and others do not, and have a conversation about the reasons why. Too many young people have struggled when they felt they had to choose between clear scientific evidence and the beliefs they grew up with. Even when parents and leaders are unsure about evolution, they can help students by saying, “While I have concerns about evolution, I’ve heard that some Christians accept the science of evolution while still believing in the God of the Bible.”

Difficult issues like origins cannot be addressed in a single event. People need time to ponder the issues, and spaces to talk it through. One church did a six-week sermon series, with parallel curricula for all ages in Sunday school, so that families could work through it together. Another church did a sermon series and discussion group for adults for four weeks, to prepare parents before a four-week series for the youth group. Other churches encourage small groups to read a book on science and faith and discuss a chapter a week. (Since all authors have their favorite view, I recommend discussing at least two books from different authors to learn about multiple Christian positions.)

More Than Evolution

In our science-saturated culture, evolution is not the only science topic the church should be considering, and not even the most important. With church members encountering the latest medical advances as patients and family members, a discussion on bioethics would be very relevant. Since young people are usually the first to use hot new gadgets, they should be considering the appropriate Christian use of technology . As the issue of climate change becomes more pressing every year, churches need to talk about it, and not avoid it because it is so political. The Evangelical Environmental Network offers many resources for churches, emphasizing ways that creation care benefits the poor and the unborn. One group of churches, with the help of Calvin College, joined together to clean up the local creek that drains the watershed in which the parishioners live, work, and worship. Many of the congregants were not even aware of the size of the watershed or the pollution level in their own creek. This was a hands-on opportunity for all ages, directly caring for their own corner of God’s green Earth.

More Than Controversy

With so many issues to discuss, Christians can easily get the feeling that science is always attacking the faith. It is essential to balance such conversations with positive responses to God’s creation. After all, the primary response to the natural world in the Bible is to praise the God who made it. The first time I led an adult Sunday school class on creation and evolution, I was amazed how much the participants appreciated simply ending each session with a Psalm reading or creation hymn. Thoughtful frowns turned into relaxed smiles as the group remembered our unity in Christ and the centrality of God as the Creator.

Creation themes can be incorporated throughout worship. One church asked the congregation to submit their favorite creation photos at the end of the summer (from backyard flowers to National Parks), then wove the images into a worship service with creation songs and readings from the Psalms. In addition to flowers and mountains, modern science has revealed incredible glories that can inspire our praise and reflection. Several contemporary Christian musicians have begun to artfully incorporate the wonders of the natural world into their music; Chris Rice sings of “cratered moon and Saturn’s rings,” and Third Day praises the “God of wonders beyond our galaxy.” In one church, an elder brought in modern science when leading the congregation in prayer with these words: “Creator God, out of nothing you created all that is. You hurled the galaxies through time and space. . . . The universe is your hourglass, the continental drift your minute hand, the Grand Canyon your second hand. You are infinite.”

Preachers can incorporate science in the same way they make references to movies, current events, or best-selling books in sermons. To notice these connections, take some time to encounter science: read the science section of the New York Times, visit a local science museum, or ask scientists in the congregation about their work. A visit to a planetarium might give a new appreciation for the vastness of the universe, which could illuminate a sermon on the vastness of God’s forgiveness in Psalm 103:11–12. Pastor John Van Sloten learned about the neural networks in the brain and incorporated it into a sermon on the vine and the branches of John 15.

Preachers are understandably concerned about avoiding scientific errors when preaching, but this should not prevent engagement with science. Some pastors do their own research to get the details right because they enjoy digging into a science topic. Other pastors bring in a scientist (live or by video) so that they do not have to explain the technical material themselves. Others play to their strengths by choosing topics with fewer technical details, such as the Christian motivation for doing science or exposition of Bible passages relevant for scientific questions. Many of the questions Christians have are really about biblical interpretation and Christian theology, areas where the pastor is an expert. Minor technical errors made in good faith are forgivable, but a sermon that argues that mainstream science is wrong on some point can be devastating for the faith life of teenagers who are learning the correct science in school.

Beyond Sunday morning worship and preaching, science can show up in many areas of church life. During a youth camping trip or church picnic, include a nature walk concluded with praise. After a winter evening worship service, invite a local amateur astronomer to set up a telescope in the parking lot to show people the moon and planets. Convert a vacant lot near church into a community garden, so kids can experience firsthand how God provides food from the Earth.

More Than Programs

In all these activities, remember that views on science are “caught” more than “taught.” Congregants will naturally pick up on the attitude of the pastor or ministry leader, whether skeptical of science or celebrating science as the study of God’s creation. Visitors will pick up on this too, so these attitudes are part of being a church that welcomes and ministers to scientist Christians . Recently I was invited to speak at a church on the expansion of the universe and the possibility of a multiverse. Several enthusiastic young people in attendance had clearly caught the love of science from the church leaders who planned the event. One girl came up afterward with her dad, both of them marveling at God’s creation. They were amazed not just with the particular things I had discussed, but with the way in which God has embedded wonders at every level of understanding. Everyone can marvel at the starry skies, school kids can learn about the planets and asteroids, and scientists with PhDs can study dark matter and string theory. No matter how deep we look, we keep discovering more and more ways that creation declares the glory of God.

Like any theory, Darwin’s idea that evolution proceeds through natural selection was once merely a hypothesis. In this post, we’ll look at some of the early observations Darwin made on biogeography: the study of where species are distributed across the globe. These lines of evidence would later prod him to consider the possibility that species arise through a natural process of gradual change over time, rather than being independently created in each location where they are found.

The curious case of the missing mammals

As a widely-travelled naturalist on the HMS Beagle, Darwin studied a large number of different environments and documented the species he found in each. The Beagle, engaged as it was in an effort to map the coastline of South America, naturally paid call to numerous island groups along the way, including islands at a great distance from a continent (i.e.oceanic islands). One observation that Darwin made about oceanic islands is that none that he studied had terrestrial mammals on them. Later work, after his voyage, would confirm that this was a general rule. Oceanic islands lack terrestrial mammal species, except for small species that were introduced by humans. In contrast, flying mammals (i.e. bats) were found on oceanic islands, and often these species were endemic (i.e. found nowhere else in the world but the island in question).

Darwin found these observations difficult to square with his (then) working assumption that species were independently created in (and specifically created for) the locations in which they are found across the globe. He discusses these observations, and the questions they raised in his mind, in two chapters entitled “Geographical Distribution” in his Origin of Species. After discussing the similar case that amphibians (such as frogs, newts, and so on) are also not to be found on oceanic islands, he turns his attention to the missing mammals:

Mammals offer another and similar case. I have carefully searched the oldest voyages, but have not finished my search; as yet I have not found a single instance, free from doubt, of a terrestrial mammal (excluding domesticated animals kept by the natives) inhabiting an island situated above 300 miles from a continent or great continental island.... It cannot be said, on the ordinary view of creation, that there has not been time for the creation of mammals; many volcanic islands are sufficiently ancient, as shown by the stupendous degradation which they have suffered and by their tertiary strata: there has also been time for the production of endemic species belonging to other classes; and on continents it is thought that mammals appear and disappear at a quicker rate than other and lower animals. Though terrestrial mammals do not occur on oceanic islands, aërial mammals do occur on almost every island. New Zealand possesses two bats found nowhere else in the world: Norfolk Island, the Viti Archipelago, the Bonin Islands, the Caroline and Marianne Archipelagoes, and Mauritius, all possess their peculiar bats. Why, it may be asked, has the supposed creative force produced bats and no other mammals on remote islands? On my view this question can easily be answered; for no terrestrial mammal can be transported across a wide space of sea, but bats can fly across. Bats have been seen wandering by day far over the Atlantic Ocean; and two North American species either regularly or occasionally visit Bermuda, at the distance of 600 miles from the mainland. I hear from Mr. Tomes, who has specially studied this family, that many of the same species have enormous ranges, and are found on continents and on far distant islands. Hence we have only to suppose that such wandering species have been modified through natural selection in their new homes in relation to their new position, and we can understand the presence of endemic bats on islands, with the absence of all terrestrial mammals.

(As an aside, it’s important to note that Darwin, when he discusses the “supposed creative force” is not here arguing against the existence of God as creator in general, but rather against the “ordinary view of creation” common at the time: that God had episodically created species at specific geographical locations (what were called “centers of creation”) and that biogeographical patterns could be explained with limited dispersal from those centers. Darwin himself held to this common view at the start of his voyage on the Beagle, and that is the model he is attempting to refute in Origin, since it was a prevailing view among scientists at the time. Darwin and many of his scientific contemporaries also had no difficulty viewing natural processes as part of God’s regular action in the world, as is evident in Darwin’s correspondence with American botanist Asa Gray, among others.)

So, for Darwin, his biogeographical observations sat at ease with his (later) ideas of colonization and subsequent species change through natural selection, but made no sense to him if one held to an independent creation model. Many oceanic islands were very old, yet no mammals had been created there. Many oceanic islands had habitat suitable for mammals (or, indeed, for amphibians, as he notes) yet no such species had been created for that suitable habitat.

Island endemics and their continental “allied species”

Darwin noticed more than the absence of certain species groups on oceanic islands. He also noticed an interesting feature of the species that were present: an endemic species on an oceanic island would often have strong similarities with a species on the mainland closest to the island in question. Additionally, the pairing of oceanic endemic species with continental species often seemed to override expectations that species found in similar environments would be more similar to each other. These observations prompted him to reflect further on the possible means by which these “closely allied species” arose. As Darwin would write in his Origin this repeated pattern made a significant impression on him, and further caused him to doubt that endemic species had been individually created for each oceanic island. His visit to the Galapagos would prove instrumental on this point:

The most striking and important fact for us in regard to the inhabitants of islands, is their affinity to those of the nearest mainland, without being actually the same species. Numerous instances could be given of this fact. I will give only one, that of the Galapagos Archipelago, situated under the equator, between 500 and 600 miles from the shores of South America. Here almost every product of the land and water bears the unmistakeable stamp of the American continent. There are twenty-six land birds, and twenty-five of these are ranked by Mr. Gould as distinct species, supposed to have been created here; yet the close affinity of most of these birds to American species in every character, in their habits, gestures, and tones of voice, was manifest. So it is with the other animals, and with nearly all the plants, as shown by Dr. Hooker in his admirable memoir on the Flora of this archipelago. The naturalist, looking at the inhabitants of these volcanic islands in the Pacific, distant several hundred miles from the continent, yet feels that he is standing on American land. Why should this be so? why should the species which are supposed to have been created in the Galapagos Archipelago, and nowhere else, bear so plain a stamp of affinity to those created in America? There is nothing in the conditions of life, in the geological nature of the islands, in their height or climate, or in the proportions in which the several classes are associated together, which resembles closely the conditions of the South American coast: in fact there is a considerable dissimilarity in all these respects. On the other hand, there is a considerable degree of resemblance in the volcanic nature of the soil, in climate, height, and size of the islands, between the Galapagos and Cape de Verde Archipelagos: but what an entire and absolute difference in their inhabitants! The inhabitants of the Cape de Verde Islands are related to those of Africa, like those of the Galapagos to America. I believe this grand fact can receive no sort of explanation on the ordinary view of independent creation; whereas on the view here maintained, it is obvious that the Galapagos Islands would be likely to receive colonists, whether by occasional means of transport or by formerly continuous land, from America; and the Cape de Verde Islands from Africa; and that such colonists would be liable to modification;—the principle of inheritance still betraying their original birthplace.

Many analogous facts could be given: indeed it is an almost universal rule that the endemic productions of islands are related to those of the nearest continent, or of other near islands.

Rethinking independent creation

For Darwin, both of these observations (that oceanic islands lacked terrestrial mammals, and that endemic species on islands were most similar to a species on the closest mainland) had the same explanation: his hypothesis that endemic, oceanic species were the modified descendants of a colonizing species from the nearest continent. This also explained the lack of amphibians and terrestrial mammals (but allowed for bats) - simply based on the ability of these classes of life to disperse across large expanses of ocean. Those that could disperse and colonize oceanic islands would experience modification in the new environment, and species unable to colonize these islands would never appear. To Darwin’s thinking, this explanation was wholly more satisfactory than the assumption that God had independently created every endemic species in its place, and arbitrarily chosen that oceanic islands did not need terrestrial mammals and amphibians.

Despite Darwin’s musing on the biogeographical patterns he observed, and the strong suggestion these patterns made of species change over time, a mechanism for that change would take some time for him to imagine. In our next post, we’ll look at that mechanism: Darwin’s idea of natural selection, and the evidence he assembled in its support prior to publishing the Origin.

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

ECF History

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

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

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

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

The Grantees

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Blessed be God for thaw, for the clear drops
that fall, one by one, like clocks ticking, from
the icicles along the eaves. For shift and shrinkage,
including the soggy gray mess on the deck
like an abandoned mattress that has
lost its inner spring. For the gurgle
of gutters, for snow melting underfoot when I
step off the porch. For slush. For the glisten
on the sidewalk that only wets the foot sole
and doesn’t send me slithering. Everything
is alert to this melting, the slow flow of it,
the declaration of intent, the liquidation.

Glory be to God for changes. For bulbs
breaking the darkness with their green beaks.
For moles and moths and velvet green moss
waiting to fill the driveway cracks. For the way
the sun pierces the window minutes earlier each day.
For earthquakes and tectonic plates—earth’s bump
and grind—and new mountains pushing up
like teeth in a one-year-old. For melodrama—
lightning on the sky stage, and the burst of applause
that follows. Praise him for day and night, and light
switches by the door. For seasons, for cycles
and bicycles, for whales and waterspouts,
for watersheds and waterfalls and waking
and the letter W, for the waxing and waning
of weather so that we never get complacent. For all
the world, and for the way it twirls on its axis
like an exotic dancer. For the north pole and the
south pole and the equator and everything between.

We tend to think of creativity in terms of flashes of insight and brilliance, of novelty, and especially of unexpected things bursting upon the scene. But creativity is no less creative and no less remarkable when it proceeds step by step, according to discipline, according to rule. We notice significant ruptures in the flow of things and upheavals of the regularity and predictability of life, faith, or science, precisely because such revolutions happen against a background of the ordinary. Even when the rules are interrupted and disturbed, they are usually not obliterated but modified. We and the rest of creation begin again by applying them anew and continuing on in light of what has changed.

Artist Linnéa Spransy makes this paradoxical ‘rules and rupture’ quality of life the method, not just the subject of her art, bringing a fascination with the mathematical underpinnings of the natural world together with her commitment to the kind of renewal-through-brokenness that comes with following Christ. As she says, “the boundaries between art, worship and natural sciences are fluid. I go [to that place of intersection] to be more amazed by the strangeness of existence, to experience awe and wonder.”

Confronted with the scriptural assertion that “eternity is written in [our] hearts,” Spransy wondered how we even begin to understand what that means. What might visual corollaries for such a statement be? How do we represent the tension between freedom and constraint, that dynamic dance of continuity and change, of predictability and surprise, that exists at every level of our experience and study of the world—from quantum physics to genetics to geology—and that seems fundamental to the ways of the Lord with us, as well? Her answer began to form around the study of fractals, mathematical rules whose reiteration in nature leads to endlessly new things. In her own work, a similar fractal sensibility leads to visual representations of something eternal.

Spransy says that every painting she completes “is the manifestation of a predetermined scheme – a system of small limits, with a clear beginning and end. These scripted pieces of visual choreography are allowed to accrue to show me their beauties and surprises, allowing discovery in the midst of certainty.” In other words, images like Frenetic Sequence, 2011, above, are not pictures of natural systems or objects, but representations and results of the processes and relationships by which natural systems and objects come to be. They are built from the inside out, as it were.

To begin a piece, Spransy assembles a library of “research drawings” that play out the various rules and rule sets she intends to use—essentially a kind of preliminary modeling of the visual system she wants to explore. Sometimes these are based on fairly simple mathematical or geometric rules that tell her when a line or shape will turn or divide or end. Other times she uses several different sets of rules at the same time—whether mathematical or derived from biological relationships such as those between base pairs on the DNA strand, or the way bacteria will move towards available sources of food in a Petri dish. But though these rules are established at the outset of a new piece, when she begins a new large-scale work, the outcome is anything but mechanistically predetermined, for several reasons.

First, the physical context in which she’ll be exploring each basic “module” or set of rules is different from that of her research drawings, having moved from a sheet of paper onto large prepared canvases that are five or six feet on a side. She does not transfer the small drawing from the paper to canvas, but regards that earlier work as preparation and practice of the process out of which the final work will emerge. Second, because the works are hand-drawn, there is always the element of her own agency and engagement with both the materials and the rules. There is an inescapably subjective quality to the way she responds to both materials and means. There is also subjectivity to the way she engages with the lines and shapes she has already laid down. Put another way, the abstraction of the rules is always mediated by and expressed through specific, very concrete and physical circumstances.

Finally, Spransy’s process includes what she thinks of as cataclysmic events or moments of chaos: intentional ruptures of the emergent system by gestures that overwhelm and obliterate sections of what she’s already done. Often she will shield sections of the existing system from the coming trauma either by masking them off or by subtly manipulating the flood of color—tilting the canvas to preserve sections of what was there. Afterwards, she will continue scribing and painting lines from the original system on top of or adjacent to the new areas of color, but in ways that respond and adapt to the new visual ecosystem. In this way, layers of work are built up, obliterated, and built up again.

Again, there is an inescapable agency at work in what—from the imagined standpoint of the system itself—must seem a randomly destructive occurrence, but Spransy’s point in breaking into the system is to test the limits of its creative, integrative capacity. By creating “environmental pressure” in this way, then coaxing the fragments and remnant information to multiply and reassert their orderly identities again, she asks, “How flexible are the rules?” The finished paintings are not rote recitations of fractal or statistical formulae, then, but objects with both a physical and a relational history. They are records of a thoughtful, physically engaged, but also humble exploration of how the confluence of order and chaos creates meaning.

Though Spransy denies that there can be such a thing as a “perfect analogy,” her artistic practice has spiritual underpinnings and spiritual implications, as well as visual results. Like many working scientists, she is seeking a way of understanding how the creator engages with His creation, and a better grasp on how we creatures should make our way in response. On one hand, her attentiveness to the basic orderliness of the material creation has a corollary in the familiar disciplines of faith, including reading the scriptures, prayer, and responding with mercy to ruptures in human lives and communities. But on the other hand, her embrace of surprise and chaos is, as she says, an “invitation to the otherness of God,” and a recognition that radically “dissimilar things sometimes occupy the same space.” In combination, those divergent elements help Spransy’s works hover at the boundary between knowing and un-knowing, between control and accident, between freedom and determinism.

Spransy notes that “even in the aftermath of great destruction, life is given great opportunity. In science we’re actually happy and excited when there’s a break in the rules.” This insight, clarified and lived out in her life as well as her artistic practice, directs us to consider not only the necessity and goodness of diligent pursuit of the rules, but also to reconsider the goodness of what we are otherwise inclined to see as calamity and chaos. Indeed, Spransy’s work points us back to the central paradox of the Christian faith: that the most radical disruption of the natural systems of the world occurred two thousand years ago in Palestine with the coming of Christ—singular proof that rupture does not necessarily end in destruction, but may be our means to redemption.

Linnéa Gabriela Spransy grew up in rural Oregon in a community attentive to Christ’s call to live in community with one’s neighbors, but was herself equally aware of God’s presence in the natural world around her. She received her BFA in Drawing from the Milwaukee Institute of Art and Design, and her MFA from the Yale University School of Art. In the midst of exhibiting in solo and group shows in university and commercial galleries, she moved to Milwaukee to study the Bible and consider how it might re-frame her sense of self and her career as an artist. In 2005 she relocated to Kansas City to help found the Boiler Room, a prayer-focused intentional community where she lives and in which she is the artist in residence. She continues to show her work widely, has pieces in pubic and private collections, and was the subject of a recent film-making project: Linnéa: Freedom Through Limits. More of her art can be seen on her website.

With the complete genome sequence in hand, we knew the sequence and location of our genes, but what we didn’t know was how all those genes are regulated: how do the trillions of cells in our bodies know when to turn on or off all those genes? How do the hundreds of distinct cell types develop and function together, when they are all running on the same DNA “operating system?”

That’s where the ENCODE (short for Encyclopedia of DNA Elements) project comes in. Launched in September 2003, shortly after the announced completion of the Human Genome Project, the goal of the ENCODE project is “to build a comprehensive parts list of functional elements in the human genome, including elements that act at the protein and RNA levels, and regulatory elements that control cells and circumstances in which a gene is active.” In other words, the project seeks to understand how the genome “works.”

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

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

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

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

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

According to the abstract of one of the lead papers from Nature, this extraordinary glut of data “enabled us to assign biochemical functions for 80% of the genome, in particular outside of the well-studied protein-coding regions.” Only 2% of the genome codes for proteins, but 80% or more has some biochemical function. As a Science news article put it, these 30 papers “sound the death knell for the idea that our DNA is mostly littered with useless bases.”

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

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

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

So with all this in mind, is ENCODE a stunning victory for ID, as Luskin believes? Bryan College biologist Todd Wood thinks not. He writes, “I don't think that function equates to design, nor do I think that design requires or predicts function. They're not the same thing… my understanding of function does not require me to hypothesize God (or an anonymous designer, if you must) as the proximal cause.”

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

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

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

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

A special thanks goes to Darrel Falk, Mark Sprinkle, Kathryn Applegate, Dennis Venema, and Tom Burnett for their contributions to this post.

Singer/songwriter Andy Zipf’s “Stumble on the Line” is built around the image of a river flowing through a canyon it has sculpted—an image that can easily be played out as a picture of the way that the Lord has been at work preparing a path for us in the material world, complete with signposts to his former and present activity. Zipf’s imagery of flowing water as a powerful (even dangerous) but also refreshing force echoes the similarly-complicated place of springs and rivers and seas in the scriptures; his description of his own path through the canyon calls to mind the Psalmist’s affirmation that his help comes not from the idols erected on the heights, but from the maker who has crafted both heaven and earth. Here, the river has literally made the canyon, carving it through the “years and layers,” and leaving the evidence of that long work as a sign to all who journey through.

But though Zipf’s canyon provides shelter, a good measure of necessary constraint, and even encouragement to keep moving along the river-course, the thrust of the song is that seeking God is a complicated, sometimes difficult endeavor, whether we are looking for Him through what He has made or through what He has said. The lyrics suggest that walking with the Lord is a path of halting discovery and intrigue, of our learning to notice the way God’s actions in the past are written subtly into the world around us. But Zipf also implies that this is a path that requires obedience, since we are also confronted with the fact that He sometimes speaks to us directly and unequivocally, saying, “follow me.” The song does not take its name and refrain from the river itself, then, but from how we tend to navigate and respond to the terrain it has carved: we “stumble on the line.”

Though pursuing the text’s geologic conceit a bit further is possible, what is more poignant for all of us engaged in the science and faith dialogue is that “Stumble On the Line” is at its heart a love song addressed to the “you” that is the river—the one who has carved the path and along whose banks the singer and we pick our way. Our attentiveness to this terrain of faith does not come first from our desire to analyze and categorize the “evidence” of how it came to look as it does, or even to demystify the mechanism by which a message might be written “in a line of stones.” Rather, what leads us on is the desire to know how to relate to the water itself. The song describes not just a physical path, then, but one of the heart and will.

Indeed, the personal address of the song focuses our attention on the fact that the subtlety or obviousness of the signs along our way have much less to do with whether or not we heed them than does the basic dividedness of our hearts. As Zipf says, we alternate between “trying to reach” and “trying to leave” the One we love. Put another way, we do not reject how God has written his past activity into the layers and years of the earth, or spelled out his intentions for us in the future because they are not obvious, but for the same reason we reject any and all of His claims on us at one time or another: because we wish to be the ones who forge the path, write the story, and sing the song. Our pride—whether in our science or our righteousness—is what keeps us blind and deaf to His leading in our daily path. And yet, even—perhaps especially—in response to our pride, God makes a way for us to gain a better perspective, and leads us on towards Him through whatever means we need.

To return to the language of the song, there is a beautiful ambivalence to the word “stumble,” that contains reminders that following the Lord involves being ever surprised by His ways (we “stumble on” his truth as an unexpected discovery), and ever broken by our own ways (we “stumble on” our pride as an impediment to seeing and following). Yet in both cases, our stumbling leaves us in the same position: on our knees before the one who is both maker and guide. In the last few repeated lines of the piece Zipf affirms that we must and will continue to stumble on in this path of love, whether we come to each stumbling place through surprise and joy, or pride and brokenness. From that position of humility and worship we have the proper perspective to see and affirm that the God who creates is the God who speaks is the God who redeems—the Lord who meets us on our knees, lifts us up, and guides us into the steps of His righteousness.

“Stumble On the Line”

© 2009 by Andy Zipf

I walk a weathered canyon
you're the rapids, running through it
years and layers start to show
in the soil, there is a swelling, beating rhythm to it
earnest prayer I used to know

on the one side, I reach you
on the other, try to leave you
in between the faults of my youth
I stumble on the line to love you

came upon a message,
hidden in some shallow water,
written in a line of stones
telling me to go on down the canyon, follow after. . .
so I keep on. . .

on the one side, I reach you
on the other, try to leave you
in between the faults of my youth
I stumble on the line to love you

I walk a weathered canyon
you're the rapids, running through it
years and layers start to show
in the soil, there is a swelling, beating rhythm to it
earnest prayer I come to know

on the one side, I reach you
on the other, try to leave you
in between the faults of my youth
I stumble on the line to love you.

Though now based in Washington, DC, Andy Zipf began life in the Midwest (Indiana, Illinois, Iowa), but moved to Pennsylania and then New Jersey before his family settled in northern Virginia. He began his career as a professional singer and songwriter shortly after high school, and has performed over 400 times in the last four years—in living rooms, coffee houses, churches, concert halls, and bars. Though “Stumble on the Line” comes from Andy’s 2009 ep “Our Voice Is a Weapon,” his third full-length album and seventh studio release, “Jealous Hands,” became available in July, 2011. More details on Andy and downloads of his music may be found on his website.

The Denisovans, an extinct hominid group that interbred with modern humans, made the news again lately with the publication of a more detailed study of their genome. One of the many interesting findings was that the Denisovans share the same chromosome 2 fusion that modern humans have. In this post, I review what we know about the origins of human chromosome 2, and then discuss the new Denisovan findings and their implications.

The origins of human chromosome 2: a brief review

Though I have discussed the evidence for a fusion event leading to human chromosome 2 before, perhaps a brief review of the evidence is in order. The human genome is made up of 23 pairs of chromosomes (for a total of 46 chromosomes). This makes us something of an oddity among living great apes, all the rest of whom have 24 pairs of chromosomes (for a total of 48). Given that there are many independent lines of evidence that support the conclusion that we share a common ancestor with other great apes, this poses something of a conundrum: how is it that our species arrived at this specific chromosome number? If we were to represent this “problem” on a phylogeny, or tree of relatedness, it would look something like this (not to scale):

Our closest living relatives, chimpanzees and bonobos, both have 48 chromosomes, as do all other great apes such as gorillas and orangutans. This pattern has one of two explanations, one of which is much more likely than the other. Either the common ancestor to these species had 48 chromosomes, and there was an event that reduced that number to 46 specifically on the lineage leading to humans (option A), or the common ancestor species had 46 chromosomes, and there were independent, repeated events that increased chromosome number in all other great ape species (option B). We can compare these options by placing the required event(s) on the phylogeny (again, not to scale):

It should be obvious that the option that requires the fewest events is the more likely one – in this case option A with an event that reduces chromosome number in the lineage leading to humans. The other option, that of repeated, independent events to increase chromosome number, remains a formal, but unlikely, possibility. Events that reduce chromosome number are not frequent occurrences, so Option A is more likely than Option B.

We can also find further support for Option A, because it predicts a specific type of event, namely one that reduces chromosome number. Since loss of a large amount of chromosomal material is almost always detrimental, we need an event that reduces chromosome number without losing information. One way for this to happen is for two chromosomes to fuse together and become one. Initially, this event would produce an individual with 47 chromosomes, where two different chromosomes get stuck together. Contrary to what is often assumed, this individual would be fertile and able to interbreed with the others in his or her population (who continue to have 48 chromosomes). In a small population, over time, two relatives who both have one copy of the fusion chromosome may mate and produce some progeny with two copies of the fused chromosome, or the first individuals with 46 chromosomes. Since either a 48-pair set or a 46-pair set is preferable for ease of cell division, this population will either eventually get rid of the fusion variant (the most likely outcome), or by chance will switch over completely to the “new” form, with everyone bearing 46 chromosome pairs. While not overly likely, this type of event is not especially rare in mammals, and we have observed this sort of thing happening within recorded human history in other species. Some mammalian species even maintain distinct populations in the wild with differing chromosome numbers due to fusions, and these populations retain the ability to interbreed.

Further evidence for a fusion event in the lineage leading to modern humans comes from comparing synteny, or gene locations and orders on chromosomes within modern great apes – an issue we have discussed here before. In brief, what we see in human chromosome 2 is exactly what we would predict for a fusion event. When compared to other great apes, we see the genes on human chromosome 2 match up, in order, with two smaller ape chromosomes. We also see that sequences used at the tips of chromosomes are present at the proposed fusion site, and that human chromosome 2 has not one but two sites for the cell cytoskeleton to attach to for cell division – but that one of the sites is mutated and not functional, though it lines up precisely with the location of this site on the appropriate ape chromosome. Together, this evidence consistently supports both common ancestry for humans and great apes, and specifically that the difference we see in our chromosome numbers arose due to a single fusion event. I briefly discussed this evidence in my last post where I describe how I teach some of this material and the compelling impact it has on students exploring the evolution question for the first time.

Enter the Denisovans

With that as background, we are now prepared to appreciate a new finding that comes from genomics work done on the Denisovan hominids, an archaic species that is more closely related to Neanderthals than to us, but that nonetheless interbred with some anatomically modern humans as they migrated out of Africa and populated the globe. (For those not familiar with the Denisovans, or the evidence for our interbreeding with them, both Darrel Falk and I have written on this previously, here and here). Recently, a more detailed understanding of the Denisovan genome was published, and nested in the new information is the discovery that the Denisovans share the 46 chromosome set with the same fusion that we have. This strongly supports the hypothesis that the fusion event predates the separation of our species. If we were to represent this on a phylogeny, we can now place this event with more accuracy than before (as before, the phylogeny is not to scale):

Despite this new information, one obvious question remains. Did the Neanderthals also have the 46-pair set? From looking at the phylogeny above, we can see that the most likely answer is that they did, since the fact that the Denisovans had it strongly implies that the last common ancestor of humans and Neanderthals / Denisovans had it as well, and the Neanderthal-Denisovan split comes later. While the Denisovan DNA samples are of high enough quality to make this assessment, we do not yet have Neanderthal DNA of high enough quality to do the same analysis with current methods (though one additional feature of the new work on the Denisovan genome is developing more sensitive DNA sequencing techniques that may resolve this question in the future).

In other words, this fusion seems to be an ancient one, predating our species by several hundred thousand years. Present estimates of the last common ancestor between humans and Neanderthals / Denisovans range at about 800,000 years ago.

Implications for understanding our “becoming human”

The main implication from this work is that it places the fusion event well before the advent of our species. I’ve often chatted informally with Christians about evolution, and at times some have thought that this fusion event was what “started” our species, or made our species unable to interbreed with other groups. Some have even suggested that perhaps the fusion event was what produced the first human (i.e. Adam).

Note that thinking this way suggests a misunderstanding of how chromosome fusions occur and what effect they have on their hosts. A fusion does not precipitate a speciation event, but rather the individual with the fusion remains a part of his or her population, and able to interbreed, even if with reduced fertility. Also, there is no necessary biological effect or change that the fusion produces on the appearance of the organism. These misunderstandings aside, however,what this new evidence shows is that this fusion event took place long before modern humans arose at around 200,000 years ago. Indeed, the 800,000 years ago date for the last human - Denisovan common ancestor means that this is the most recent date possible for the fusion. While it is an interesting piece of our evolutionary history, it doesn’t seem to have much to do with how we came to acquire the traits that set us apart from, and ultimately outcompete, other similar species.

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

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

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

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

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

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

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

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

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

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

David Lack

Ornithologist David Lack

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

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

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

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

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

Whereas Charles Darwin spent only nineteen days on the shores of the Galápagos, Lack and his crew conducted more than five months of meticulous and exhausting study in the harsh climate. At that time, even the finches themselves provided little solace. Lack wrote,

Darwin’s finches are dull to look at, not only in their orderly ranks in museum trays, but also when they hop about the ground or perch in the trees of the Galápagos, making dull unmusical noises. Only the variety of their beaks and the number of their species excite attention.¹²

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

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

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

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

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

David Lack's drawing of 14 species of Galápagos finches, p. 19 of Darwin’s Finches

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

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

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

Iconic Finches

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

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

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

Lack's image of beak adaptations from Darwin’s Finches

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

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

Conclusion

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

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

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

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

Eugene Dubois

13 years before, in 1877, Dubois had arrived in Amsterdam to study medicine, but always harboring a desire to study the ancestry of modern humans. So, after four years at the University there, he accepted an invitation to go to the University of Utrecht to study comparative anatomy and devote himself to the latest thinking about the origins of the human species. It was during his time at Utrecht (from 1881 to 1887) that Dubois became enamored of Haeckel’s views on human origins, which differed from those of Darwin. While Darwin argued that humans had evolved in Africa, the region in which our closest living relatives—the chimpanzees and gorillas—still live, Haeckel believed that the origins of humanity lay in East Asia. This was so, he believed, because of his own observations of gibbons that walk bipedally when on the ground.

Haeckel also believed that there had once been a large landmass called Lemuria between the continents of Africa and Asia. In his view, Lemuria had since become submerged, leaving the modern islands of Madagascar and the East Indies as its only remains. The idea of submerged continents was not unusual for the late 19th-century, as people struggled to understand the character of biological diversity present in the world and why there were such striking similarities between animals that were geographically dispersed. The geographical distribution of marsupial fossils in South America and Australia is an example of this sort of problem, and one that was not solved until the second half of the 20th century when continental drift reconstructions suggested that ancient marsupials had used Antarctica as a conduit between the other two continents. Not only did such theories make sense of modern distributions, they were confirmed with later discoveries of marsupial fossils in Antarctica.

In any case, in 1888 Dubois joined the army and set out for the Dutch East Indies to pursue his ideas. For the next two years, he would comb Sumatra attempting to locate the hominin remains that Haeckel promised would be there. In hindsight, what Dubois was attempting was something that had never been done before: discovery of hominin material through the tools of archaeological excavation. Up to this point, all of the human fossils had been found on the surface, eroding out of the side of a bank, or as a result of farming. It had not occurred to anyone to go looking for human ancestors.

Now, with his supply of prison workers dwindling due to desertion and fever, he had almost run out of options and was on the verge of failure. Using almost all of his remaining resources, he decided to abandon his excavations on Sumatra and turn to the nearby island of Java. Emboldened by the fact that early modern human fossils had been discovered there (at Wadjak), he arrived and settled in at Trinil, on the banks of the Solo River, in 1890.

Figure 1: Dubois' Pithecanthropus erectus

The very next year, Dubois’ long-standing efforts were finally rewarded, first with the discovery of a skullcap (calvaria) of a hominin cranium, and then with an intact femur (Figure 1). Judging by what he knew of cranial anatomy, Dubois estimated that the skull would have been approximately 900 cubic centimeters (cc) in volume, placing it below even the lowest threshold of modern humans. Further, he noticed that it was not like modern humans in shape, being too long and low. He concluded that it showed “evidence of a form intermediate between man and the anthropoid apes” (Dubois, 1896). Dubois envisioned a sequence of forms in which the gibbon gave rise to a form of chimpanzee called Anthropopithecus sivalensis, which then gave rise to the form represented by the Trinil remains, after which Homo sapiens arose (Turner, 1895).

Dubois spent the next twenty years on the road with his find, trying to drum up support for its place in human prehistory. As with Raymond Dart’s discovery of the first australopithecine thirty-three years later, Dubois did not receive a warm reception. Most critics simply said that he had gotten it wrong and that the femur did not belong to the same individual as the obviously-primitive skull cap. Some of the criticism Dubois suffered could have been mitigated had he been more open to sharing the Trinil materials; but, instead, he allowed very little access to the bones, so that very few people knew exactly what they looked like. Adding to Dubois’s credibility problems was the 1911 “discovery” of Piltdown. This intentional hoax turned the paleoanthropology world on its head for forty years, sending researchers down innumerable rabbit holes. As I noted in a previous post, the Piltdown remains made all of the other hominin finds appear too “ape-like” to be on the road to humanity and informed many opinions about finds such as those from Trinil.

On the other hand, some critics of Dubois’ new hominin claim were vicious, and questioned both his academic abilities and his judgment (Shipman & Storm, 2002)—in addition to the interpretation of the find itself. It was in reference to Dubois’ work that the term “Missing Link” was first used with reference to a particular human fossil, originating with Charles Lyell (1863) and describing palaeontological gaps. And ironically, it was in one of the most stinging criticisms of Dubois’ work that the name that would eventually stick was first used: “Homo erectus.” Eventually, many other finds in the same general area and across Southeast Asia demonstrated that what Dubois had found was a real, previously-unknown hominin form, and the first to colonize the Asian continent and the islands leading off towards Oceania.

Homo erectus across South East Asia:

Figure 2: Sangiran 17

Sangiran

The earliest point at which Homo erectus appears to have begun to colonize the greater East Asian region is around 1.8 million years ago, represented first by the partial child’s skull found at the site of Modjokerto, and then, at around 1.66 million years ago, at the site of Sangiran, in Trinil, where Dubois had made his landmark discovery. This site was rich, yielding the remains of many crania, perhaps best represented by Sangiran 17 (Figure 2), an almost complete skull.

The material from the Sangiran site is very diverse morphologically, with some crania having capacities of as little as 700 to 800 cc, and other, larger heads with volumes in the range of 1000 cc. As with the late Homo ergaster finds from Africa, the remains from Sangiran yielded crania that were still widest at their bases, possessing large brow ridges. Some have thick cranial bones and are very robust (Sangiran 4), while others are very gracile (Sangiran 31). What this variation means is not clear, but most workers believe it represents a very diverse diachronic population (that is, one group living and moving around over a long period) rather than separate species inhabiting the area. The Sangiran site yielded fossil material in an almost continuous succession from approximately 1.66 million years ago to less than 800,000 years ago.

Because the area of the excavations—the Sangiran Dome—is a volcanic deposit, the layers have been securely dated by the ⁴⁰Ar/³⁹Ar method, although questions remain about the historical sequence and distribution of other animals that lived there through the ages (its faunal succession). The problem is that many of the fossils were not found in context, and relating them directly to the stratigraphy is tenuous. Despite this, most workers are comfortable with the earliest hominins in the region being at least 1.5 million years old.

One of the things hampering workers in this region is the comparative paucity of recovered stone tools. Those that have been found suggest a technological stage similar to the late Oldowan design, equivalent to that being created by the Homo ergaster populations inhabiting the area of Dmanisi and East Africa. Unfortunately, none of the tools have been associated with the hominins directly so it is not exactly clear who made them.

Figure 3: Sambungmacan 3

Sambungmacan

Another major find from the area where Dubois brought Homo erectus to light is the cranium from the site of Sambungmachan. This skull was reportedly found in 1977 but was then illegally sold to the antiquities market, where is spent considerable time in different collections before being “rediscovered” in 1998—in a New York nature curio shop called Maxilla and Mandible, Inc. (Delson et al., 2001). This was an almost-complete calvaria (Figure 3), with only part of the base missing. It is equivalent in size to the fossils from Sangiran, with a cranial capacity of around 1000 cc. It has a large brow ridge extending all of the way across the top of the eyes, a long, low cranium with a sloping forehead and a maximum width near the cranial base—all features that are also characteristic of the late African H. ergaster and Sangiran crania. Although we will never know exactly how old this cranium is, its morphology is consistent with that of the material from Sangiran.

Figure 4: Ngandong 6

Ngandong

Later in time, but also located on the Solo River, is the site of Ngandong, excavated by Oppenoorth in the early 1930s. At this site, fourteen calvaria have been discovered, all of which show advanced Homo erectus characteristics: long and low in shape, with thick-bones and a distinctive brow-ridge. (Figure 4). As with the other Indonesian finds, dating the Ngandong material has been problematic. The deposits at the site were originally thought to be around 100,000 years old, but this interpretation was turned on its head in 1996, when Swisher and colleagues claimed that the deposits were no older than between 27,000 and 53,000 years old (Swisher et al., 1996). These age estimations were made on the associated fauna, however, and as Rainer Grün and the late Alan Thorne pointed out, the faunal material does not match the skulls either in color or in texture and is likely not from the same time. Recently, Swisher and colleagues revisited the dating of the site and derived internally-consistent dates of at least 143,000 years before the present (Indriati et al., 2011). As with the Trinil remains, however, there are no associated stone tools.

Homo erectus in China

The Chinese Homo erectus material is very widely scattered and working in the region has presented many difficulties for researchers in terms of transport, language barriers and funding. Consequently, we know less about this region and its previous inhabitants than we do about most other areas of the Old World. Although there are between ten and fifteen sites that have yielded Homo erectus material, I will only touch on the most important ones.

Lantian:

Figure 5: Lantian

In the early 1960s, a cranium and mandible were found in the cave of Lantian, Shaanxi province, whose characteristics matched other remains from China designated as Homo erectus. Paleomagnetic dating has yielded a date no earlier than 1.15 million years ago for the skull, with the consensus being that it is around 800,000 years old. A date of approximately 650,000 years before the present was derived for the mandible. The cranium is heavily encrusted and suffered from postmortem deformation (Figure 5). When reconstituted, it was found to have a capacity of around 780 cc (low for Homo erectus) and the bones on the sides of the head are the thickest yet recorded. At this site some flake tools, mammal remains, and an ash deposit were all recovered, suggesting hunting and control of fire.

Figure 5: Hexian

Hexian

Another almost-complete calvaria was found at Longtandong cave in the province of Hé Xiàn, dated to between 400,000 and 500,000 years ago. This find exemplifies typical Homo erectus in many ways in that it is long and low, with heavy muscle markings toward the base and the rear of the skull (Figure 6). The cranial capacity is around 1000 cc, a third-again greater than that of the Lantian calvaria. Its cranial shape is very similar to those found in Southeast Asia, suggesting that it straddles the Southeast Asian and Chinese boundary.

While both Lantian and Hexian were significant finds, another site in China boasted the single largest collection of Homo erectus fossils ever found at one site, as well as presenting one of the greatest mysteries in paleoanthropology. Tomorrow, in the conclusion of our look at Homo erectus in Asia, we’ll peer into the Zhoukoudian caves and consider how this species fits into the lineage of man.

One thing I ask from the LORD,
this only do I seek:
that I may dwell in the house of the LORD
All the days of my life,
to gaze on the beauty of the LORD
and to seek him in his temple.

I belong in the ranks of those who have cultivated the beauty that is the distinctive feature of scientific research.

Beauty in Science

As a biologist, I am fascinated by the fluorescent-on-black images of cells, 3D rotations of protein structures, and cross-sections of colourful tissue samples that grace the covers of scientific journals. I have spent whole weeks staring down a microscope at the beautifully transparent bodies of developing fish embryos, and whenever possible I illustrate my written work with photographs of the natural world. I’m not alone. In the institute where I did my PhD we had a basement full of microscopes and imaging technology, and it was considered important to have beautiful images in your presentations—movies were even better. The journal Nature: Cell Biology always features striking images on its covers, and in an editorial these photographs were described as works of art in their own right. In fact, ‘scientific art’ has become a recognised genre, and displays of science-related images are increasingly popular in research institutes, museums, science festivals and other public spaces.

Indeed, a number of practicing scientists have devoted their time outside the lab to communicating the beauty and wonder of science to the general public. (See sidebar.) One of these is Dr. Lynne Quarmby, a cell biologist who’s passionate about explaining her work to people outside of the scientific community. She writes a regular column, a ‘nexus of mystery, art, literature, beauty and science,’ for the online literary magazine Numéro Cinq.

If we can recognize and acknowledge that our direct biological senses, as wonderful as they are, give us only a tightly pinched and cloudy view of the world, then we open ourselves to unimagined beauty.

Lynne Quarmby, Numero Cinq, 2011³

Biologists often label themselves according to the ‘model organism’ that they work on. I was a zebrafish person, and Quarmby is a Chlamydomonas person. Chlamydomonas is not an STD (you’re thinking of Chlamydia), but a gentle single-celled algae that is in all likelihood swimming around the standing water in your garden as you read. This microscopic creature is easy to grow in the lab (a jam jar on a sunny windowsill will do), its genome has been sequenced, and it is a surprisingly powerful tool for studying human disease.

Chlamydomonas was not an obvious choice for medical research, but the secret is in the cilia. Cilia are hair-thin appendages that wave around in a coordinated fashion to move their owner from A to B. But these algae don’t spend their whole lives swimming around. When they reproduce, their cilia are absorbed back into the cell body (scroll to the 4th video here). When conditions are stressful, the cilia simply drop off. Quarmby and her students studied Chlamydomonas mutants that hold on to their cilia, and discovered a family of proteins involved in the regulation of both cilia and cell division.

At the same time as Quarmby was studying the behaviour of cilia in Chlamydomonas, medical researchers were identifying genes that are mutated in humans. The same proteins involved in cilia and cell cycle control in Chlamydomonas were affected in some patients with polycystic kidney disease. What’s the connection? Cell biologists knew that most of our cells have cilia on them, but assumed that they were not important. Our cells generally do not swim around, unless they’re sperm. It turns out that these tiny appendages are involved in a whole range of vital cell functions. The cilia on kidney cells are important for sensing the flow of urine, and without these the kidney cannot function properly.

Perhaps beauty is in the eye of the beholder when it comes to unicellular flagellates, but what I appreciate is the detail. To see the minutiae of cell structure is stunning, particularly when you know how difficult it is to achieve images like the ones in this article in the journal Cytoskeleton, or even the image of an adult rat head, below. And little Chlamydomonas, a microscopic pond dweller, has advanced our understanding of a devastating human disease. This combination of aesthetic experience and elegant scientific explanation is what I find beautiful. ⁴

It appears to be a universal experience for scientists to find beauty in their experimental systems. Perhaps this is because the daily discipline of examining anything in detail brings an appreciation of its finer points. Or maybe the process of choosing something to study and then spending the greater part of one’s waking hours staring at it provokes something akin to the loyalty of the mother who thinks her child is beautiful, despite the large pimple on its nose. But even bearing in mind the fascination and devotion of the true professional, there seems to be something more in the scientist’s experience of beauty.⁵ Most, I think, simply delight in the beauty of creation. For some, this gives a sense of the transcendent: a sort of natural spirituality. For a Christian, this encounter with beauty draws them nearer to God.

Christian Appreciation of Beauty in Science

One of the driving forces behind the work of many of the early scientists was their Christian faith. The astronomer Johannes Kepler (1571-1630) initially hoped to pursue theology, but was eventually satisfied that science was also a way to glorify God.⁶ Many others, including the famous naturalist John Ray (1627-1705), were ordained clergy in addition to their academic studies, so their science and theology were naturally interwoven. Others, like James Clark Maxwell (1831-1879), examined Christianity as rigorously as their scientific experiments.

These pioneering scientists (or ‘natural philosophers’, as they called themselves back then) were encouraged by a rich tradition of theology that wholeheartedly encouraged their exploration of creation. The Hebrew Scriptures tell how creation reveals the glory, generosity and faithfulness of God who created and sustains everything.⁷ The beauty of the land and everything in it is celebrated: mountains and trees, plants and animals, men and women.⁸ A number of the earliest Christian theologians, the Church Fathers, often expressed their delight in the details of animal and plant life, and what we now understand as ecosystems.

Diversity of beauty in sky and earth and sea…the dark shades of woods, the colour and fragrance of flowers; the countless different species of living creatures of all shapes and sizes…the mighty spectacle of the sea itself, putting on its changing colours like different garments, now green, with all the many varied shades, now purple, now blue.

Augustine, The City of God

Theologian Jame Schaefer has surveyed the writings of many of the Church Fathers and Medieval theologians, and found five broad themes in their contemplation of creation.⁹

• Affective appreciation: Simply delighting in what is seen.
• Affective-cognitive appreciation: A deeper, scientific study of creation leads to even greater joy for the beholder.
• Cognitive appreciation: Thinking in more abstract ways about the beauty of the interconnected universe. Each part plays its unique role for the greater good of the whole.
• Incomprehensibility: Being overwhelmed by the magnitude and complexity of the universe and everything in it.
• The sacramental quality of the physical world: The world God has created mediates something of God’s presence and character to us.

One of my favourites among the theologians covered in Schaefer’s work was an unnamed Cistercian who in the twelfth century wrote extensively about the grounds of the abbey in which he lived, and the surrounding countryside. He was obviously very happy with his vocation, and had a good understanding of the interconnectedness of the different factors: water, weather and crops - an early ecology. Basil of Caesarea (ca. 329-379) spent time observing animals and plants, noting similarities and differences, and encouraged others to do the same, giving glory to God for everything he saw. Hugh of Saint Victor (1096-1144) delighted in what his senses could tell him about creation, so enabling him to praise the Creator all the more, and lamented that others might pass such an opportunity by.

An important Medieval figure in the early development of science is Albert the Great (ca. 1200-1280), teacher of Aquinas, who wrote on “the importance of observation and experimentation in field and laboratory studies of animals, plants, metals, and inorganic elements”. He carried out field studies, and “legitimised the study of the natural world as a science within the Christian tradition.” For him, appreciation of creation had both cognitive and emotional aspects.

For all of these early scholars, to study creation and enjoy its beauty was an activity that everyone should engage in using their God-given intellect. Their detailed exploration of the wonders of the universe was fuelled by faith in a benevolent creator God, and this deep intellectual study led to heartfelt praise for the one who made it. Is this something we can share?

I try to avoid using the words ‘nature’ or ‘the natural world’ as much as possible because of the ambiguity of the word nature, which is often wrongly used to create a divide between natural and supernatural worlds. This is ancient Greek philosophy and has nothing to do with the God of the Bible. When addressing Christians I usually use the word ‘creation’ in its traditional theological sense, meaning ‘everything that exists apart from God’, without connection to any one particular interpretation of Genesis 1-3.

There are two opposite errors which need to be countered about the fossil record: 1) that it is so incomplete as to be of no value in interpreting patterns and trends in the history of life, and 2) that it is so good that we should expect a relatively complete record of the details of evolutionary transitions within all or most lineages.

What then is the quality of the fossil record? It can be confidently stated that only a very small fraction of the species that once lived on Earth have been preserved in the rock record and subsequently discovered and described by science.

There is an entire field of scientific research referred to as "taphonomy" -- literally, "the study of death." Taphonomic research includes investigating those processes active from the time of death of an organism until its final burial by sediment. These processes include decomposition, scavenging, mechanical destruction, transportation, and chemical dissolution and alteration. The ways in which the remains of organisms are subsequently mechanically and chemically altered after burial are also examined -- including the various processes of fossilization. Burial and "fossilization" of an organism's remains in no way guarantees its ultimate preservation as a fossil. Processes such as dissolution and recrystallization can remove all record of fossils from the rock. What we collect as fossils are thus the "lucky" organisms that have avoided the wide spectrum of destructive pre- and post-depositional processes arrayed against them.

Soft-bodied organisms, and organisms with non-mineralized skeletons have very little chance of preservation under most environmental conditions. Until the Cambrian nearly all organisms were soft-bodied, and even today the majority of species in marine communities are soft-bodied. The discovery of new soft-bodied fossil localities is always met with great enthusiasm. These localities typically turn up new species with unusual morphologies, and new higher taxa can be erected on the basis of a few specimens! Such localities are also erratically and widely spaced geographically and in geologic time.

Even those organisms with preservable hard parts are unlikely to be preserved under "normal" conditions. Studies of the fate of clam shells in shallow coastal waters reveal that shells are rapidly destroyed by scavenging, boring, chemical dissolution and breakage. Occasional burial during major storm events is one process that favors the incorporation of shells into the sedimentary record, and their ultimate preservation as fossils. Getting terrestrial vertebrate material into the fossil record is even more difficult. The terrestrial environment is a very destructive one: with decomposition and scavenging together with physical and chemical destruction by weathering.

The potential for fossil preservation varies dramatically from environment to environment. Preservation is enhanced under conditions that limit destructive physical and biological processes. Thus marine and fresh water environments with low oxygen levels, high salinities, or relatively high rates of sediment deposition favor preservation. Similarly, in some environments biochemical conditions can favor the early mineralization of skeletons and even soft tissues by a variety of compounds (eg. carbonate, silica, pyrite, and phosphate). The likelihood of preservation is thus highly variable. As a result, the fossil record is biased toward sampling the biota of certain types of environments, and against sampling the biota of others.

In addition to these preservational biases, the erosion, deformation and metamorphism of originally fossiliferous sedimentary rock have eliminated significant portions of the fossil record over geologic time. Furthermore, much of the fossil-bearing sedimentary record is hidden in the subsurface, or located in poorly accessible or little studied geographic areas. For these reasons, of those once-living species actually preserved in the fossil record, only a small portion have been discovered and described by science. However, there is also the promise of continued new and important discovery.

The forces arrayed against fossil preservation also guarantee that the earliest fossils known for a given animal group will always date to some time after that group first evolved. The fossil record always provides only minimum ages for the first appearance of organisms.

Because of the biases of the fossil record, the most abundant and geographically widespread species of hardpart-bearing organisms would tend to be best represented. Also, short-lived species that belonged to rapidly evolving lines of descent are less likely to be preserved than long-lived stable species. Because evolutionary change is probably most rapid within small isolated populations, a detailed species-by-species record of such evolutionary transitions is unlikely to be preserved. Furthermore, capturing such evolutionary events in the fossil record requires the fortuitous sampling of the particular geographic locality where the changes occurred.

Using the model of a branching tree of life, the expectation is for the preservation of isolated branches on an originally very bushy evolutionary tree. A few of these branches (lines of descent) would be fairly complete, while most are reconstructed with only very fragmentary evidence. As a result, the large-scale patterns of evolutionary history can generally be better discerned than the population-by-population or species-by-species transitions. Evolutionary trends over longer periods of time and across greater anatomical transitions can be followed by reconstructing the sequences in which anatomical features were acquired within an evolving branch of the tree of life.

“The heavens,” wrote the psalmist “declare the glory of God.” (Ps 19:1 NIV)

The universe that inspired the psalmist three thousand years ago grows grander as each new generation of astronomers adds yet another layer of understanding. Each new discovery pushes back the boundary that separates the known universe from the vast terra incognita that beckons and teases us to keep going, to sail ever further from familiar shores.

A few centuries ago the great philosopher Immanuel Kant repeated the psalmist’s declaration: “Two things fill the mind with ever new and increasing admiration and awe, the more often and steady reflection is occupied with them: the starry heaven above me and the moral law within me. Neither of them need I seek and merely suspect as if shrouded in obscurity or rapture beyond my own horizon; I see them before me and connect them immediately with my existence."

The night sky still beckons us, as it once did the psalmist. I spend time each summer at a rustic family cottage in the wilderness of my native New Brunswick, Canada. There, miles from electricity, the night sky does not compete with artificial light. Smog does not obscure it. Planes do not draw white trails on it. It does not compete with cable television or even cell phones, silenced by the absence of signals. The night sky is simply there, quietly declaring the glory of God. Its many lights reflect off the ripples of the lake, and are accompanied by the rustling of leaves and the voices of the many creatures that call this wilderness home. Only a jaded soul could sit by that lake and not wonder if there wasn’t some larger meaning to the experience.

I can see what the psalmist saw and rejoice as he did. But I watch the night sky through the eyes of a twenty-first century scientist. I have the benefit of centuries of scientific advancement and can see, in my mind’s eye, so much more. Those visible stars are just the advance guard of an almost infinite army of stars going back almost forever. The stars are not attached to a dome that one might reach with an ambitiously tall tower or puncture with a long-range missile. They are so far away that their light has been traveling at unimaginable speed for years, centuries, milennia and longer. The light from the stars in the Hyades Cluster began its journey to the earth at about the time that my ancestors—Loyalists from Pennsylvania—began their journey to this part of North America in the eighteenth century. The light from the closest stars, the trio that make up Alpha Centauri, takes over four years to reach earth. The most distant star ever detected from the earth is a “gamma ray burster” that launched its signal almost 13 billion years ago, when the universe was young. The powerful gamma ray signal from this star began its journey before our planet was even formed, reaching the earth in April 2009.

The psalmist did not know that the stars were made of hydrogen and helium. He did not know they generated their energy through nuclear fusion or that many of them explode at the end of their lives. He knew nothing of galaxies and the layers of structure in the cosmos. He did not understand how fast light travels or that the light from our sun powers photosynthesis and many other processes here on the earth.

The universe brought into view by science is like a collection of Russian matryoshka dolls nestled one inside the other. With the psalmist we can see the outer layer—and it is grand. But inside are additional layers, each one with a new type of grandeur. And at the very end of the unpacking lie the remarkable laws of physics that keep the earth orbiting about the sun, the sun shining reliably, and the sunlight providing energy to sustain life on our planet.

The universe as we understand it today inspires awe. And for those open to its message—from the psalmists of yesteryear to the believers and even the thoughtful skeptics of today—it speaks of a Creator. Our universe does not look like a cosmic accident, where lots of stuff just happened. It looks like the expression of a grand plan—a cosmic architecture capable of both supporting life such as ours and of inspiring observers like us to seek out the Creator.

This is why Antony Flew—“world’s most notorious atheist”—changed his mind and started believing in God.

Despite a common desire among Christians to find evidence for the activity of the creator God in the natural world, the Scriptures themselves more often give us images and analogies of God’s providence rather than “proof” that would be admissible in peer reviewed journals, much less in court. In his final climactic week in Jerusalem, Jesus used image after image, parable after parable to convey the urgency of his message that the Kingdom of God was coming to pass through his own coming Passion.

Though His disciples did not understand them at first, it was by new pictures (the lost coin, lost sheep and lost sons) and reinterpreted old ones (like the vineyard), that they came to understand the “facts” of His healing miracles and, ultimately, His death and resurrection. By reframing concrete happenings and material relationships, stories and images opened up possibilities rather than limiting them—and they still invite us to enter into them, rather than leaving us dispassionate and disconnected.

As we remember the narrative that takes us from Good Friday through Easter morning, the image of a buried grain of wheat invites us into the story rather than just describing what happens in it. Certainly this is an image for Christ Himself, but as I’ve written elsewhere, the seed isn’t just a symbol of His death and rebirth from the grave, but a promise of future abundance, lavish reproduction, and a pointer to the coming harvest: Jesus Himself is the “first fruits” of the new creation. We are called not only to be workers for that harvest, but to be, like Him, the harvested grains. As Christ entered into His glory through self-sacrifice, so we, too, give ourselves in order to share in and contribute to the shalom—the comprehensive flourishing—promised as the marker of God’s Kingdom now and in the future.

This combined image of death and renewal, single seed to field, is the heart of John Crumb’s hymn “Now the Green Blade Rises,” first published in 1928 in the Oxford Book of Carols and originally set to an old French Christmas carol (“Noel Nouvelet”). By clicking the image above you can hear a new version as revised and re-arranged by contemporary hymnist Alex Mejias. We offer it as a meditation on the sacrifice and victory of Jesus, the glorious promise of resurrection, and the call upon us all to join in God’s story of redemption and renewal.

Now the green blade riseth from the buried grain,
Wheat that in dark earth many days has lain.
Love lives again, that with the dead has been:
Love is come again, like wheat that springeth green.

In the previous post in this series, we explored how evolution can force science into making predictions that seem counter-intuitive. For cetacean (whale) evolution, we saw that the preliminary lines of evidence (the fact that whales are vertebrates, and mammals, for instance) pointed to the prediction that modern whales are descended from four-limbed, land-dwelling ancestors. As we then noted:

Instantly this prediction raises a host of uncomfortable questions: where did their hind limbs go? How did they acquire a blowhole on the top of their heads when other mammals have two nostrils on the front of their faces? How did they transition to giving birth in the water? What happened to the teeth of the baleen whales? What happened to the hair characteristic of mammals? and so on. In some ways, evolutionary thinking about whales creates more difficulties than it appears to solve.

And yet, these difficulties are the stuff of science. If indeed our “educated guess” of terrestrial, tetrapod ancestry for whales is correct, the evidence will show that these transitions, challenging though they may seem, did indeed occur on the road to becoming “truly cetacean”.

We have already discussed hind limb and hair loss in whales, citing evidence from embryonic development in modern whales that shows how hair and hind limbs develop early in their embryogenesis, but then are lost at later stages. We now turn to one of the remaining questions: tooth loss in the lineage leading to modern toothless whales (order Mysticeti). To obtain their food these whales pass seawater through a baleen, a large sieve-like structure that filters out plankton, small fish and other food items. Some recent genetics sleuthing has investigated a portion of this riddle, and adds further details to the story of how the baleen whales came to be.

Evolution: A Theory with Bite

If indeed modern whales are descended from ancestral, four-limbed, terrestrial ancestors, then those ancestors, like mammals in general, had teeth. Modern toothed whales (order Odontoceti) have retained those teeth to the present day, but baleen whales have adopted a new way of life as filter-feeders. Researchers were curious to see if traces of a “toothed past” could be found in the genomes of modern baleen whales, so they went hunting for remnants of genes devoted to making teeth. Such defective gene remnants would be examples of pseudogenes, and we have discussed pseudogenes previously in this series. While pseudogenes in and of themselves are powerful evidence for evolution, pseudogenes that are “out of place” are especially so. One such example we have seen before is the human vitellogenin pseudogene, the remains of a gene used for yolk production in egg-laying organisms found in the exact location in the genome that evolution would predict for it. As mammals that receive embryonic nourishment through a placenta, we have no need of egg-yolk genes. Similarly, baleen whales have no need for genes responsible for making teeth, and finding the remnants of such genes would make a strong case for an evolutionary origin of baleen whales as the modified descendents of toothed whale ancestors.

Independent Lines of Evidence, but Contradictory Stories?

Some of the genes known to be used in all mammals for tooth formation were the obvious candidate genes to start with: the products of the ameloblastin, amelogenin, and enamelin genes are all used in the formation of tooth enamel, the hardest structure in the vertebrate skeleton. Researchers went looking for these genes in several Mysticete (i.e. toothless whale) species. The results showed that all the species studied did indeed have these three genes present as pseudogenes (and more specifically, as unitary pseudogenes, a special class of pseudogene we have discussed in detail previously). Finding these genes as pseudogenes in toothless whales was exactly what evolution predicted, but there was a catch: none of the mutations that removed the functions of these three genes were shared between different species, suggesting that these genes lost their function independently in the species studied. This finding was at odds with data from the fossil record, which suggested that teeth were lost only once, and early in the lineage leading to all modern toothless whales. So, the researchers seemed to have two lines of evidence that at face value contradicted each other. The fossil record suggested that tooth loss occurred once in the common ancestor of all toothless whales, but these three genes seemed to have been inactivated independently, several times over, suggesting that loss of teeth should be happening later in Mysticete evolution, and more than once.

One proposed explanation for the apparent discrepancy (among several put forward) was to predict that a fourth gene required for enamel formation was lost early in Mysticete evolution. The loss of any one gene necessary for forming enamel would be enough to prevent the process altogether. In this case, the loss of this fourth gene would prevent tooth enamel from forming, even though the genetic sequences of the other three enamel genes would still be intact. Once enamel function was lost, random mutations in the remaining enamel genes could then accumulate later in Mysticete evolution after speciation in this group was already underway. To test this hypothesis, the research group went hunting for other enamel genes in toothless whales.

Signature in the SINE

The smoking gun for tooth loss in Mysticetes turned out to be exactly what was predicted: a fourth gene, necessary for enamel production, and mutated with the same inactivating mutation in all modern toothless whales. The gene in question, named enamelysin, was destroyed when a mobile genetic element called a SINE transposon inserted into it, breaking it into two halves and removing its function:

The fact that the same SINE insertion mutation at an identical location is found in all modern Mysticete species indicates that this mutation happened once in a common ancestor and then was inherited by the entire group. Since this must have occurred early in the evolution of toothless whales in order to happen in the common ancestor of the entire group, the picture from the genetics and the fossil record match. Once again, findings in one discipline (in this case, paleontology) can be used to make very detailed predictions about what another, unrelated discipline (comparative genomics) should reveal. These results are also entirely consistent with the observation, made in the 1920s, that toothless whales form tooth buds during embryogenesis that are later reabsorbed prior to the point when the deposition of enamel would begin. As with the hind limb story in whale evolution, lines of evidence from genetics, paleontology and embryology converge to support the hypothesis that modern toothless whales descend, through modification, from toothed ancestors.

In the next post in this series, we’ll examine a few more lines of evidence for whale evolution, and extend our discussion to converging lines of evidence for the evolution of our own species.

My curiosity immediately led me to see what he had cut out. All of the miracles and the Resurrection passages were gone, and the Gospels were rearranged in a linear fashion, edited and pasted together as a single narrative. Then I looked particularly to see what Jefferson did with John 11.

Why John 11? For the past several seasons of Lent, I have been meditating upon this account of three siblings: Martha, Mary and Lazarus of Bethany. In particular, John 11:35 has become a central passage for me to consider in self-reflection, because an artist learns very early that creativity demands boundaries and limits to thrive. When I began on my recent journey to illuminate the Four Holy Gospels for Crossway publishing's celebration of the 400th anniversary of the King James Bible, I needed to find a thematic boundary. I was so overwhelmed with the grand scale of the project that I chose this shortest passage in the Bible—“Jesus Wept”—and that decision has led to many discoveries along the way.

"Jesus Wept" is, to me, the most profound passage in the Bible. After I gave a recent lecture on this verse at Duke University, Richard Hays commented on my reflections: "The Incarnate Word of God stood wordless at Bethany." Indeed, Jesus' tears make no logical sense, as he came to Bethany with the specific mission to raise Lazarus from the grave. He told the disciples his mission (and why he intentionally delayed his arrival, knowing that Lazarus lay dying) and revealed to Martha that he was and is the "Resurrection and the Life." So why did he, upon seeing the tears of Mary, waste his time weeping, when he could have shown his power as the Son of God by wiping away every tear, telling people like her, "Ye of little faith, believe in me!"?

In my reflections, this "irrational," emotional response from Jesus became a central means to understand the role and even the necessity of art in the midst of suffering—what I have began to call our "Ground Zero" conditions. Art, like the tears of Christ, may seem useless, ephemeral and ultimately wasteful. But even though they evaporate into our atmosphere, the extravagant tears of God dropped on the hardened, dry soils of Bethany, or onto the ashes of our Ground Zero conditions, are still present with us. Because tears are ephemeral, they can be enduring and even permanent, as with “Jesus wept.” In the same way, perhaps our art can be so as well. What seems, at first, to be an irrational response to suffering may turn out, upon deep reflection, to be the most rational response of all.

Predictably, "Jesus Wept" did not make into the Jefferson Bible. John 11 was cut out entirely, falling onto the floor of his Monticello home and discarded, along with Martha's confession. Jefferson's rationalism allowed only a distant deity that made sense in reference to objective ‘scientific’ calibrations, not ephemeral marks of compassion. Yet, when this attitude is actually applied to the sciences, they also become, like Jefferson's Bible, a “cut and paste” product, based on a limited viewpoint.

Even with my rudimentary understanding of the early phonetic and acoustic research my father was part of at Bell Labs in the 1970s, I know that the optimism of many scientists there was based on reductionistic assumptions. I described my father’s wrestling with the basic theses of linguistic research in a previous essay:

In the 1980s, [while in his] early 50’s, my father began to send a series of notes to his colleagues questioning the basic tenets of acoustics research, as he found them flawed and inadequate for the goals pursued. . . .[W]hat the early research assumed was that by segmenting speech patterns, you could have enough data to rebuild speech. It would be a bit like dissecting a frog, and stitching it back together, only to expect it to jump again -- A typical reductionist/modernist assumption. (Refractions 24: "The Resonance of Being")

My father began to challenge these underlying but over-simplified assumptions and as a result, came under criticism for abandoning many of the positions held by his peers. I continue:

My father’s Converter/Distributor theory (C/ D theory) assumes that computer technology is now capable of anticipating contextual patterns of speech, and is able to simulate an architectural structure to account for the morphing of speech production. Rather than the segmental approach, he calls his new thinking prosodic, as it accounts for the complexity of speech and language. But it would take years of research to get to a point of presenting his new ideas to the linguistics/phonetics community.

My father, who had rarely had problems finding support for his research before, was in for a battle. . . . He could not find funding, and found himself fighting the establishment of the research world—the very establishment he had helped to build. After my father’s many futile attempts to secure funding for his new research, my brother, a successful entrepreneur in Silicon Valley, stepped in to fund a post for a graduate student at Ohio State, to help my father compile enough data to be able to begin his research.

To my father, the integrity of the scientific process demanded such a course. He never considered that his challenge to reductionism would be seen as a threat by many of his colleagues. He simply was seeking after Truth.

Even in the objective rigor of the research process, then, human factors intervene—sometimes for better, sometimes for worse. Our presuppositions surface eventually, and it becomes clear where we place our "faith. " My father's C/D theory is an intuitive leap, arising from his love for synthesis and beauty, but pulled up by hard data and a stubborn commitment to the truth of matter. It is an example of the way intuitive, subjective insight can connect the ephemeral with the rational, objective and concrete. Should we seek, then, to make the sciences a Jeffersonian cut-and-paste re-narration of our reality? Are we so inflexible in how we will understand the great mystery of our being? If so, the gap between that reduced ‘reality’ and what is truly human is the very gap into which Jesus' tears still fall.

Jesus wept for Lazarus, but also, perhaps, for Jefferson as he snipped out John 11 with his own hands; for to dismiss Jesus’ tears as irrational and unnecessary is to miss Jesus entirely. Jefferson sought to cut out the Deity, but also lost the Man. Without Jesus' full humanity, coupled with his Divinity, we do not have a Savior. Without this fullness of humanity—concrete and ephemeral, intuitive and objective—we lose perspective on why we are doing our research to begin with. If we assent to the fragmenting, segmental assumptions of modernity, we will have stitched the frog back together only to bury him anyway. If the dead are to live, we will require a Miracle Worker to show us that the world that is cohesive, and rational, but only when seen through a veil of tears.

When astrophysicist Dr. Jennifer Wiseman first published the following posts as a paper in the BioLogos Scholarly Essay series, the essay’s subtitle asked the question, “Can Recent Scientific Discovery Inform and Inspire Our Worship and Service?” Over the next few weeks, we will look at Dr. Wiseman's answer to that query—an emphatic “Yes!”. But in this first installment we begin by describing some of the reasons such a posture of worship through science is not more common in the contemporary church than it already is.

Oh Lord My God, when I in awesome wonder, Consider all the worlds Thy hands have made; I see the stars, I hear the rolling thunder, Thy power throughout the universe displayed.
Then sings my soul, my Savior God, to Thee; How great Thou art, how great Thou art

(Carl Boberg, 1885; Trans. Stuart Hine 1949)

The words of this great hymn convey the proper overwhelming sense in which the wondrous Creation of God should translate directly into a response of awe and praise from mind, body, and spirit. The writer sees and hears the wonders of nature with his body, considers with his mind what all this implies, and responds with songs from his soul.

But is this worshipful response happening in our Christian congregations today? I believe this kind of response to the Creation can and should happen within the hearts of God’s people and wherever congregations of believers are gathered. Such power can even unify believers who differ on lesser matters as we all look up outside of ourselves at the same wonders and respond with the same praise. As an astronomer, I have felt the sense of being “blown away” by seeing images of countless distant galaxies, or even by just looking up at the array of stars overhead on a dark moonless night and sensing something of the “big-ness” of God.

There are impediments to realizing the fullness of this kind of worship experience for many Christian congregations today. I believe four of the main culprits are ignorance, distraction, controversy, and uncertainty.

Let me start with the first, and clarify up front that by ignorance I am simply referring to being uninformed, rather than the sometimes more negative connotations of the word. How up-to-date is the scientific knowledge of average, educated, committed evangelical church members and pastors?Americans, both adults and schoolchildren, are not ranking favorably compared to the rest of the world’s developed nations in science knowledge these days. We enjoy our technological achievements and resulting gadgets, but true comprehension of scientific principles and recent discoveries is not a strong part of our culture and national conversation these days.

This is reflected directly in what kinds of things are (and are not) discussed in church. In my own generally very good church experience growing up in mainstream America, I can only remember science and nature being discussed in a general way (e.g., we should look at the beauty of flowers and mountains and animals and thank God), except for once in a specific way in a children’s sermon (where we were told we should not believe we came from monkeys!). That was a while ago, but how are science issues handled today? Do pastors speak about the evidence from cosmic background light for a spectacular beginning to the universe? Are the genetic codes being mapped out for animals and humans resulting in praise for God’s amazing “blueprint”? Are the advancements in nanotechnology and biotechnology and medicine subjects for discussion of good and poor uses of technology in church? The answer to these is, of course, “no”, for the most part, yet even issues seemingly more relevant to the daily lives of parishioners are often driven by current technology and scientific advancement, and an informed congregation can better understand how to praise, pray, discern, dialogue, and serve.

Related to being uninformed is the condition of distraction for many evangelical Christians today. The distractions of overloaded schedules, pressured jobs, divided families, and even church environments of entertainment-based worship and activities can impede a lifetime of quiet listening, learning, and contemplation. If there is no encouragement from church leaders to learn and incorporate nature and current scientific discovery into contemplation and praise and service, then there will be no space available in the lives and activities of congregants for what should be the resulting awe and praise.

But what does it mean to be informed about science in today’s evangelical congregations? Too often this has implied a direct relation to controversy, the third reason science is not often inspiring worship these days. There are many voices trying to “inform” Christians about science, and for the average evangelical congregant, discernment about which authority figure to believe can be difficult. Many times Christians are presented with a clear and strong implication that scientific conclusions, especially on issues related to origins of the universe and of life, are part of the secular “World” camp rather than the camp of “God’s Truth”. And Christians “know” that they must be on one side or the other of this stark line of worldliness. Often in more conservative churches a teaching will come from the pulpit that goes something like this: “Scientists tell us that *...+, but they cannot give a reason how *...+ happened; but WE know how: God is responsible!” Therefore any serious consideration of a scientific understanding of the development of the universe and life implies that one is “compromising” the teaching of the Word of God, rather than studying the details of how God works. In Scripture, however, never is the study and experience of nature seen as somehow antithetical to knowing and following the Lord; just the opposite in fact!

This often boils down to the correct interpretation of Scripture. Through sermons, radio spots, television shows, and literature, evangelical Christians are hearing adamant messages conflating the acceptance of modern scientific discovery with worldly compromise, or else providing alternative ideas that are not entirely satisfying. From Young-Earth Creationists, they hear that a literal reading of the Biblical creation account is the only correct one, so all scientific discovery must be reinterpreted to fit a recent Creation. But this robs them of the sense of awe we glean from the magnitude of space and time revealed by astronomy, geology, and fossils. From the Intelligent Design community, they hear the message that life (and perhaps the entire universe) is too complicated to develop through natural processes alone, and therefore that God’s work requires miraculous inputs of information into the natural world. This implies that somehow natural processes must not be fully God’s processes, or that God’s work through them is somehow inadequate. They also hear the message to “teach the controversy,” so that somehow by proclaiming that there is a controversy about natural processes as an adequate explanatory tool for natural history, the controversy will in fact become real. They are then surprised to find out from either advanced scientific study or from the Evolutionary Creation voices that in fact there is no great controversy in the scientific community about the basic structure and timeline of the natural history of the universe and life; that in fact there need be no theological debate about how God brought (and is bringing) the universe and life into being, rather, the issue is whether God is in fact real and responsible for all we know and are. And yet even this unifying message can sometimes seem to gloss over the central theological issues of suffering and death and fallen-ness in Creation. So every approach to origins and evolution evokes some difficulties and challenges with which the Christian congregant must grapple.

Next week, Part 2 concludes Dr. Wiseman's discussion of the stumbling blocks that can stand between the church and its appreciation of science as a means of worship, and turns to the ways that the pursuit of God through study of the created world can help overcome those difficulties by pointing us directly to the Lord.
