The second chapter of Genesis offers an enduring image for the creation of humanity: “the LORD God formed a man from the dust of the ground and breathed into his nostrils the breath of life, and the man became a living being.”

What does it mean for humanity to be created “from the dust of the ground?”

In many ancient Mesopotamian creation stories, human beings were depicted as deriving from some physical part of the gods. Often this was the result of conflict: humans arose from the blood, flesh or tears of gods slain by other gods. Humans created in this fashion were supposed to serve the gods by performing menial work that the gods had tired of doing themselves. The lot of humanity, then, was one of violence and servitude.

In the Israelite creation stories reflected in Genesis 1 and 2, however, humans are made from the ordinary material of creation: “dust.” Humans are made of earth-stuff, not god-stuff.

At first glance, it may seem that this lowers the status of the human creature. We might ask the question raised by Eliphaz in the book of Job:

Can a mortal be more righteous than God?
Can even a strong man be more pure than his Maker?
If God places no trust in his servants,
if he charges his angels with error,
how much more those who live in houses of clay,
whose foundations are in the dust, who are crushed more readily than a moth! (Job 4:17-19)

Indeed, our humble origins ought to remind us of the fragility of our lives. As the Psalmist says,

You turn people back to dust, saying, “Return to dust, you mortals.”
A thousand years in your sight
are like a day that has just gone by,
or like a watch in the night.
Yet you sweep people away in the sleep of death—
they are like the new grass of the morning:
In the morning it springs up new,
but by evening it is dry and withered.

The elements of which our bodies are made are ordinary and abundant. Science tells us that approximately ninety-three per cent of the mass in a living human body is comprised of elements first formed through nuclear fusion in the hearts of stars. Through almost unimaginably vast and ancient cycles of stellar formation and supernova explosions, this “stardust” of elements has been spread throughout the universe. It is as though God scattered the stars across space and time to seed the universe for life, including your life and mine. And we are thereby inseparably connected to each other, to the air we breathe, to the ground we tread, to all the creatures that fill the skies and crawl upon the earth and teem in the seas, to the depths of all the heavens. We are not transcendent of creation. We are creatures.

Yet we are creatures into which God breathed the “breath of life.” We are stardust and more than stardust. We are not reducible to our constituent chemicals. A “man” or a “woman” is not just a gooey sack of water, carbon and trace elements. Hydrogen, oxygen and carbon are not aware of their own existence. These elements cannot reason or pray or love or write poems. Conjunctions of these elements cannot carry any persistent identity across time. They do not exercise will or intentionality or agency. They are not “selves.”

Most of the cells in a human body are in constant flux: aging, dividing, dying, being replaced. The surface layer of human skin is renewed completely about every two weeks. An adult’s skeleton is entirely remade over approximately ten year periods. It may be that only the neurons of the cerebral cortex and a few other types of cells persist throughout the lifetime of a human body. And eventually, it all does return to “dust.”

Yet we think of ourselves as persisting over time, as comprising an “identity,” a “self.” Perhaps the cerebral cortex provides the stable biological platform for identity and selfhood, but something new emerges from the chemical-electrical soup, new patterns of organization, a different level of causation. We can even make choices that reshape ourselves, both physically and psychologically. The very wiring of our brains changes when we make conscious choices. Mind is both shaped by matter and supervenes on matter.

Materialists who wish to collapse all of human identity into brain chemistry overstep the bounds of “science.” A fundamental principle of scientific practice is testability: is it possible to demonstrate empirically whether a proposition is false ? As Saint Augustine observed many centuries ago, the fact that I acknowledge I could be “wrong” about something means that I am a “self” who is capable of making real choices about things that are in fact true or false. “Si fallor, sum” Augustine said – if I can doubt, if I can be wrong, then I must exist. One who is a true materialist “all the way down” cannot test his or her materialism. There is no possibility of “being” right or wrong, indeed no possibility of “being” – there is nothing but chemistry.

Spiritualists who wish to degrade matter in favor of the soul or spirit likewise are not expressing a Christian anthropology. Indeed, one of the first heresies that encountered the early Christian church was Gnosticism. A core belief of Gnosticism was that matter, including the human body, was essentially evil. Salvation for the Gnostics involved the soul’s escape from the prison of embodiment and materiality. The Gnostics treated the body either with disdain – engaging in extreme ascetic practices – or with antinomian abandon – engaging in extreme sexual license. Either way, their practices were rooted in the belief that matter and the body were unimportant. It’s easy to see how this view continually creeps into both our popular culture and our Church cultures.

Christian theology asserts that humans are spiritual creatures, a unity of body and spirit or “soul,” integrated, not reducible downwards to mere matter or upwards to mere spirit. Perhaps there is no better way to bring these themes together than with a Psalm — here is Eugene Peterson’s paraphrase of Psalm 139 in The Message:

God, investigate my life; get all the facts firsthand.
I’m an open book to you;
even from a distance, you know what I’m thinking.
You know when I leave and when I get back;
I’m never out of your sight.
You know everything I’m going to say
before I start the first sentence.
I look behind me and you’re there,
then up ahead and you’re there, too—
your reassuring presence, coming and going.
This is too much, too wonderful—
I can’t take it all in!

Is there any place I can go to avoid your Spirit?
to be out of your sight?
If I climb to the sky, you’re there!
If I go underground, you’re there!
If I flew on morning’s wings
to the far western horizon,
You’d find me in a minute—
you’re already there waiting!
Then I said to myself, “Oh, he even sees me in the dark!
At night I’m immersed in the light!”
It’s a fact: darkness isn’t dark to you;
night and day, darkness and light, they’re all the same to you.

Oh yes, you shaped me first inside, then out;
you formed me in my mother’s womb.
I thank you, High God—you’re breathtaking!
Body and soul, I am marvelously made!
I worship in adoration—what a creation!
You know me inside and out,
you know every bone in my body;
You know exactly how I was made, bit by bit,
how I was sculpted from nothing into something.
Like an open book, you watched me grow from conception to birth;
all the stages of my life were spread out before you,
The days of my life all prepared
before I’d even lived one day.

Calvin inherited the medieval cosmology of his time, a way of viewing the world heavily influenced by Greek thought and one which was about to receive shocks from astronomers such as Copernicus and Galileo. But not just yet. Genesis 7:11: In the six hundredth year of Noah's life, in the second month, on the seventeenth day of the month, on that day all the fountains of the great deep burst forth, and the windows of the heavens were opened.

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

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

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

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

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

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

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

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

Preaching Suggestions

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

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

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

He begins by discussing the fossil record, explaining how new forms are classified. He then explains the physically distinguishing trait of humankind—bipedalism. From the discovery of Ardipithecus, the earliest known hominin, to the australopithecines, the most prolific hominin, Kidder focuses on the discovery, the anatomy, and the interpretation of these ancestral remains. This blog was originally posted on December 10, 2010. We think it was an important one. Note though that it was posted shortly before the discovery of Denisovans. So now one more red bar needs be added to the figure above.

Transitional Fossils

Some time ago, the Discovery Institute’s Casey Luskin commented on the human origins exhibit at the Smithsonian Institution, suggesting that palaeoanthropologists use evolutionary theory to describe the progression of the human lineage even when they don’t have transitional fossils with which to work. He writes:

What's ironic, however, is that if you ask the question How Do We Know Humans Evolved? the answer you’re given is, “Fossils like the ones shown in our Human Fossils Gallery provide evidence that modern humans evolved from earlier humans.” So whether you find fossils or you don’t, that’s evidence for evolution.

Indeed, it has become an article of faith for those espousing both the young earth creation (hereafter YEC) model and many who hold to the intelligent design model that transitional fossils do not exist and therefore evolution has not taken place. Support for this position usually entails attacking the weak areas of the fossil record, where burial processes have left us little with which to work, or the creation of straw men arguments in which transitional fossils are defined in such a way that none could ever be found. Often this centers on the concept of “missing link,” a term that is habitually used in the popular press and young earth creation and intelligent design literature when referring to fossil remains but which has little to no meaning for biologists or palaeontologists. As Ahlberg and Clack (Ahlberg and Clack 2006) write:

But the concept has become freighted with unfounded notions of evolutionary ‘progress’ and with a mistaken emphasis on the single intermediate fossil as the key to understanding evolutionary transitions. Much of the importance of transitional fossils actually lies in how they resemble and differ from their nearest neighbours in the phylogenetic tree, and in the picture of change that emerges from this pattern.

Contrary to common misconceptions, the fossil record does not record one single lineage for any family of organisms but rather a series of branches, with many related species coexisting synchronously. Darwin hypothesized that the evolutionary record reflected this bushiness and drew such a diagram in his journal. At the time, though, he had little in the way of fossil evidence to back up this position. Much has changed since his day.

An analogy for understanding this “bushiness” was best described by Prothero and Buell (Prothero and Buell 2007). They suggest that the reader consider his or her own genealogy. You and your siblings are the direct descendents of your parents and, while you are similar to them, each of you has different characteristics not shared with them as well as characteristics that you do share. Your parents have siblings as well (your aunts and uncles), and your grandparents are their last common ancestors. These siblings have their own children (your cousins), who have different and similar traits relative to their parents. They are broadly recognizable as being related to you (“oh, I see you have Aunt Edna’s nose”) but three or four generations out, they will become less and less so. These are the “nearest neighbours” that Ahlberg and Clack describe. In this analogy, each of these cousins represents a transitional form from what was (your grandparents) to what will be down the road.

For example, no one would confuse a frog with a salamander but if you trace the fossil record of each back in time, eventually you encounter a fossil, Gerobatrachus hottoni which was recently discovered (Anderson et al. 2008) that is best described as a “frogamander,” having the basal characteristics of both frogs and salamanders. Had we seen such an animal at the time, it is likely we would not have found it remarkable because it would have resembled the species around it. One lineage eventually diverged into frogs, salamanders and other amphibians. Most (just like Darwin proposed in his tree diagram with the little hatch marks at the tip of many branches) went extinct.

Taxonomy and the Beginnings of Human Origins

All life is classified based on a system devised by Carolus Linneaus in 1735 in his remarkable work Systema Naturae. This system gives all recognized species an individual place based on a system of hierarchy. The study of classification is known as taxonomy. A taxonomic ranking for humans would be this:

When a fossil is excavated, the first thing that the palaeontologist does is make a taxonomic assessment of where it fits in a sequence of known fossils. Traits that are shared with other like species or genera are referred to as primitive traits. Examples of this in humans are five fingers and the presence of three arm bones. We share this with all mammals. Traits that are new or are not shared with other like species are referred to as derived traits. Examples of this in humans are the skeletal changes in the pelvis and the foot to allow for walking upright. We do not share these with any other primates.

Transitional fossils in the human fossil record are distinguished at both the genus and species level. This group includes the extinct genera Ardipithecus and Australopithecus and the current genus Homo. All species except Homo sapiens are extinct. Much of the recent study of early humans focuses on the transition from Ardipithecus (‘Ardi’) to Australopithecus (‘Lucy’ and similar fossils) and from Australopithecus to Homo, the genus that led eventually to us. While each of the australopithecine species identified in the fossil record has derived characteristics that separate them from their ancestors and from each other, only one led to the genus Homo.

In future posts, I will describe the evidence for human evolution and why this evidence is compelling. It suggests that we have had a long, varied history filled with great leaps of change, crushing defeat, and eventual expansion into all areas of the globe.

Though many believe in an ancient world-wide flood, the evidence given does not hold up to geological scrutiny, but points rather to something regional instead. It is their hope that Christians will not walk away from faith in Christ simply because a global flood is not supported by science. Looking at natural phenomena like the Grand Canyon, salt beds, and fossil deposits, they reveal reasons for these deposits and structures while showing that their origin did not stem from a violent flood that covered the planet. This is the first in a four part series taken from Gregg Davidson and Ken Wolgemuth's scholarly essay "Christian Geologists on Noah’s Flood: Biblical and Scientific Shortcomings of Flood Geology".

As Christians and geologists, we frequently encounter people with stories of storm tossed and shipwrecked faith that started when they began to wrestle with apparent conflicts between science and the Bible. The stories have a common thread. The Bible, they were told, clearly teaches the earth was created a few thousand years ago with life forms fashioned more or less as we find them today. Because the earth is very young, the incredibly complex sequence of rock, sediment, and fossils found on our planet must have been deposited in a very short period of time. Noah’s Flood, as the only plausible causal agent, was obviously a global and violent event. Theories of an ancient earth and adaptation of life forms, they were further informed, have been constructed on flimsy evidence created by atheistic scientists searching for ways to expunge God from modern culture. But as these sojourners began to explore and understand the actual evidence for an ancient earth, they found themselves increasingly convinced of its legitimacy, and thereby increasingly questioning the veracity of their faith – many to the point of relegating Christ to just another wishful myth.

It is our conviction that these stories of strained or lost faith derive not from an inherent unwillingness to trust the Bible, but rather from misguided teaching on the message of Scripture. Those insisting the earth is young are not simply putting their faith in God’s Word, they are putting their faith in their own particular interpretation of that Word. As such, an entirely unnecessary stumbling block to faith is created, where faith in Christ first requires rejection of sound science.

As we have prayed and studied this subject, we have felt God’s call to speak out against this misplaced stumbling block. We are sensitive, however, to the fact that when scientists speak on issues of faith, there is a natural suspicion that science will be regarded as the ultimate arbiter of truth, and Scripture will have to yield whenever conflict arises. It is thus important for us to state here that both of us ascribe to the authority and inspiration of Scripture, the reality and necessity of Christ’s death and resurrection, the existence of genuine miraculous events, and the truthfulness of the Biblical historical narratives. In our understanding, science will never trump Scripture, but by virtue of science being a study of God’s natural creation, it may occasionally assist in our understanding of God’s written Word. Where this has occurred historically and has been accepted by the Church, the invariable result has been the abandonment of an interpretation of some secondary importance, without any change in our understanding of the intended central message.

This phenomenon is illustrated well by the 17th century clash between Galileo’s claims that the earth revolves around the sun, and the multiple passages in Scripture that appear to clearly present a static earth as the physical center of God’s natural creation. The Bible tells us repeatedly that the earth is fixed upon its foundations (Ps 93:1, 104:5) and the sun rises and sets (Eccl 1:5, Ps 19:6). Within the context of the historical narratives (which we are not accustomed to interpreting in any figurative manner) we read statements about “the sun rising over the land” (Gen 19:23), and a miraculous event during a famous battle where “the sun stopped in the middle of the sky and delayed going down a full day” (Josh 10:13). Likewise in the Levitical law, we find commands to complete the Passover sacrifice “when the sun goes down” (Deut 16:6).

God’s people had interpreted these verses for thousands of years to be authoritative statements about both spiritual and physical realms, and 17th century believers understandably struggled with allowing science to alter traditional interpretations. If God says the sun rises and the sun sets, how could it be otherwise?

Fast forward a few centuries, and we are now somehow quite content to have allowed science to alter our thinking on these verses, without abandoning notions of inerrancy or inspiration. The reason is simply because it was eventually recognized that the primary message of these verses was never on the nature of nature, but on the nature of man and his experience with his environment and his God. Solomon and Joshua accurately recorded their experience from an earthly perspective (sun rising and setting), and David praised God for holding the earth fixedly in His hand (Ps 93:1, 104:5), without requiring a meaning of fixity in space. The central message of these verses was apparent to readers before and after Galileo. Only a secondary interpretation, likely never intended by the writers, was cast off after scientific advances.

So what is the issue regarding Noah’s Flood? The modern debate centers around two questions. Was it truly global in extent, and can the Flood account for the earth’s complex geologic record? To address the first, it is worth being reminded of the Apostle Paul’s letter to the church in Rome where he makes a statement that “your faith is being proclaimed throughout the whole world” (Rom 1:8). Entire people groups existed at this time in China, Australia, and North and South America who knew nothing of the church in Rome. Though using wording that literally means the entire world population, Paul is clearly referring to the world known to him and his readers at the time.1 Paul speaks truthfully from his experience. Allowing for the possibility that Noah’s Flood encompassed all of known humanity without necessarily covering the entire planet is thus consistent with how other passages in Scripture are interpreted by Christians who believe the Bible is authoritative and trustworthy.

Our primary interest in this blog series is the second question, the widely promulgated notion that the Flood can account for the earth’s complex geology, and that all genuine Christians should accept this viewpoint.

Notes

1. Many Biblical scholars define a literal interpretation as one that takes into account the literary genre, figures of speech, context, and author/audience perspective in deriving the intended meaning. By this definition, poetry and allegory are literally interpreted as figurative. In this blog and in our article, our use of literal conforms to its more common definition where a literal interpretation is one that adheres to the precise definition of words without figurative meaning and without requiring additional context to understand.

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.

Author's Note from Joy Walters

As I mentioned in my first post, I grew up skeptical of the whole idea of evolution. One contributor to my disbelief was the lengthy timescale for the “tree of life” that was presented with the theory. I would hear, for example, that dinosaurs lived hundreds of millions of years ago, but there was no explanation of why this was true; it was just given as a fact. No one explained the methods of dating, and so I thought biologists simply estimated the ages of species to fit their preconceived notions of how long it would take for one species to emerge from another. It also seemed like the ages were periodically revised and extended farther back in time, and I figured scientists needed to manipulate numbers to make evolution plausible. This, in my mind, made the theory both unbelievable and dismissible.

Once I learned about the techniques used to date fossils, I realized that my first impressions were wrong; the ancient ages of species are scientific determinations rather than scholarly conjectures. However, I have found in recent conversations that Christians remain skeptical of old ages and the evolutionary time scale. For this reason, I wanted the videocast to address the process of fossil dating (what the methods are and why they are accurate) while focusing on cases where hominid fossils were discovered and dated using these very methods. My hope is that Believers would be informed about the evidence for human evolution and its scientific grounding.

]]> Thu, 26 Jul 12 05:00:03 -0700 Joy Walters What scientific evidence do we have about the first humans? http://biologos.org/questions/what-scientific-evidence-do-we-have-about-the-first-humans?utm_source=RSS_Feed&utm_medium=RSS&utm_campaign=RSS_Syndication http://biologos.org/questions/what-scientific-evidence-do-we-have-about-the-first-humans?utm_source=RSS_Feed&utm_medium=RSS&utm_campaign=RSS_Syndication In recent decades, scientists have discovered more about the beginnings of humanity. The fossil record shows a gradual transition over 5 million years ago from chimpanzee-size creatures to hominids with larger brains who walked on two legs. Later hominids used fire and stone tools and had brains as large as modern humans. Fossils of homo sapiens in east Africa date back nearly 200,000 years. Humans developed hearths for fire, stone points for spears and arrows, and cave paintings by 30,000 years ago. By 10,000 years ago, humans had spread throughout the globe. Genetic studies support the same picture. Humans share more DNA with chimpanzees than with any other animal, suggesting that humans and chimps share a relatively recent common ancestor. Also, the same defective genes appear in both humans and chimps, at the same locations in the genome—an observation difficult to explain except by common ancestry. Genetics also tells us that the human population today descended from more than two people. Evolution happens not to individuals but to populations, and the amount of genetic diversity in the gene pool today suggests that the human population was never smaller than several thousand individuals. Yet all humans, of all races, are descended from this group. Humanity is one family.

Discussion about Adam as the first divine "Image-bearer" often turns on the perceived conflict between scientific evidence contradicting belief in a single biological ancestor of all living human beings and Scriptural testimony that humans were made different from the rest of the creation: we have capacity to reflect the image of God.

Many posts on this Forum have suggested that the cosmological narrative in Genesis 1 is best read as being primarily about God’s identity and agency, rather than about the physical make-up or material history of the natural world. Similarly, we demonstrate our highest regard for Genesis 2’s account of the creation of Eve—the second fully human being—by looking to its meaning in terms of spiritual and interpersonal relationships, rather than genetic ones. While the specific “how” of our being made into the image of God will probably always remain a mystery, the Bible and creeds are clear on the “why” of our creation: we were made to worship the Lord, and be in relation with Him and each other. That intimate, conscious and deeply symbolic knowledge of our maker and fellow human beings is a profound difference that sets us apart from the other creatures.

I have frequently argued that poets are often the most clear on some of the important issues of our faith, including this one. Today we feature a work by Robert Siegel, who identifies the imagination as the faculty by which we recognize and name those spiritual relationships. As he says, “It's the imagination, hence language and art, that establishes the connections”; it is the imagination that allows us to conceive of and name the links between ourselves and creation, ourselves and each other, ourselves and the Creator God.

Though we often focus on Adam’s naming of the animals, and then even of Eve, Siegel helps us remember that it was in hearing his own name that Adam’s whole humanity came into being: he experienced the richness of being called by God to bear His likeness, but also of being called to by one that was profoundly “like him.” Put another way, we are speakers, but also equally hearers. May we, too, be awakened to ourselves and our image-bearing identity by a still, soft voice saying our name. May we, too, in gratitude and delight, call upon the name of the one, Jesus, who is both our God and our fellow man.

“Adam’s Dream”

by Robert Siegel

The Imagination may be compared to Adam's dream:
he awoke and found it truth. --Keats

He saw the garden spreading past the trees
he'd been warned to avoid (yet keep a special eye on).
He'd learned by scents, transported by the breeze,
myriads of roses and how, by hand, the scion

of one to graft on another--and what was edible:
whole families of legumes, grasses, roots,
melons, peaches, apples, pears. Incredible,
the variety of tastes just from the fruits!

But it wasn't enough. Even the breathing animals
with friendly grunt or sigh, silken warm side,
and large affectionate eye were not able
to speak. When he named them, none replied:

His words fell dead on the air--though he said
them everywhere, walking or running to each place:
to the mountain, which echoed back the sounds he made,
or the still pool, returning his own gaze.

But no one answered him until one night in a dream
he woke and heard a soft voice speak his name.

As we noted in our response to the June article in Christianity Today “The Search for the Historical Adam,” the evidence for gradual creation is overwhelming, with more studies supporting the evolutionary process being published each year. We’ve looked at many of these evidences: from fossils, from comparative anatomy, from genetics. Today, we’d like to highlight for our readers a compelling video from the annual TED Conference featuring geneticist Svante Pääbo. You may remember Pääbo from his efforts to extract and sequence DNA from 30,000(+) year old Neanderthal bones (we mentioned his work here).

In this eighteen minute video, Pääbo covers a lot of ground, noting several lines of genetic evidence for the evolution of modern humans from earlier hominids in Africa, as well as for the interbreeding between early humans and Neanderthals. We’ve covered some of this data before, but it’s particularly compelling to hear it described by one of the scientists leading the field of study.

However, our goal at The BioLogos Foundation isn’t just to make the Church aware of the fascinating and convincing scientific evidence for gradual creation. As we have said before:

BioLogos exists to help Christians think carefully about the ramifications of these new data in light of long-standing traditional ways of viewing human creation. We have some re-thinking to do, but it can be done and will be done within the context of a Christian faith that is fully orthodox and thoroughly evangelical. Any time we draw closer to truth, to God’s truth, we have nothing to fear. There is still much to learn, but we can look back at what we have learned with awe—absolute awe.

It is truly amazing that we know so much now about our early days. For example, Africans do not have DNA which is specifically derived from Neanderthals, whereas people in the rest of the world do carry a small amount. This confirms the picture of human history derived from studying fossils. Neanderthal bones have not been found in Africa, so it isn’t surprising that their DNA is not there either. The fact that non-Africans have some of the DNA found in Neanderthal bones confirms that which geneticists knew from other studies: we have two distinct groups of human ancestors—those who left Africa in ancient times and those who stayed.

God chose to reveal himself and to begin working with a distinct sub-group of ancient humans, those descended from Abraham and Sarah. To Abraham, God made a marvelous promise. Drawing his attention to the stars above, God said that someday Abraham’s descendents would outnumber the countable stars in the universe. And so it came to be. Indeed through our adoption into the family, we are all children of Abraham. The God of Abraham is our God too and each one of us is one of those stars too numerous for Abraham to count.

Sometimes, it seems that we are uncomfortable with the notion that God made us through a gradual process that included apes in our family tree. It is almost as though we would prefer dirt to apes. Perhaps, in at least some cases, this is due to an inadequate appreciation for the fact that God loves, really loves, all of creation, not just us. As special as we know we are, we can’t read Psalm 104, Genesis 1, Genesis 9 (where the covenant is not just with Noah but with all living creatures), or Job 38-41 without being reminded that all living creatures are God’s creation (see here). The Neanderthals, the Denisovans, Homo erectus, and the australopithecines were God’s creation too! Still, we modern humans have been singled out. We’ve been called out.

True our family tree, as Pääbo shows here, is intriguing. But let us never forget, that the most important thing about this tree is that God is the vine which exists at its core, and we are called to be the branches which bear fruit. The fact that many of us have a small amount of Neanderthal DNA, some of us have Denisovan DNA, and others have neither is interesting, but it is really just a side issue for people of faith. As a result of God’s visit to Abraham, followed eventually by God’s taking on flesh in the person of Jesus of Nazareth, we can all know God as our heavenly Father. We are children of God and as such, we are God’s representatives. We are called to image God. We are called to love God. And we are called to love each other and to deeply respect all that he has made.

Though some may believe that moving the science/faith dialogue forward is best left to scientists, scholars, and theologians, we at BioLogos recognize that our pastors play an invaluable role in the conversation. Across the globe, pastors are helping their congregations work through difficult issues of science and faith with honesty, insight, and a gentle spirit. To this end we present an ongoing series recognizing sermons (and the pastors who give them) that are helping to promote the harmony of science and faith. Today's sermon features Pete Shaw, who is the senior pastor of Crosswalk Community Church in Napa California. The full sermon can be downloaded here. Finally, if you know a sermon or podcast related to science and faith that has especially spoken to you, please let us know.

The early chapters of Genesis appear to pose scientific problems that challenge our literal, post-Enlightenment lens through which we often read the Word of God. (See this post for a commentary on how this situation came about.) This leads many people to believe that the descriptions in these texts are meant to reveal more than raw scientific fact. Pete Shaw of Crosswalk Community Church highlights the story of Noah and the Ark to explore the possible reasons for adopting a non-literal understanding of this ancient narrative. Shaw first summarizes the story of Upnashatim in the Epic of Gilgamesh, a famous Sumerian flood story that the young and old in Abraham’s day would have known well. Upon comparison, these two accounts—the Genesis flood and the Gilgamesh flood—are incredibly similar. Furthermore, Shaw exposes the various practical problems that arise if one takes every word of the Noah story to be a precise truth. For example, he wonders how Noah could have fed and maintained every living land creature in a small boat for ten months. He also explains how a primitive understanding of the universe is heavily reflected in this text. In light of these points, he concludes that whether or not this story is portraying actual historical events, it is presenting rich truths about God, and that should be the focus of the believer.

Transcript

“The first eleven chapters of Genesis are what scholars call pre-history. In other words, they can’t really date what was going on very well in those first elven chapters. After that, twelfth chapter on, it is a lot easier to date, and the stories have a different feel, a different structure… but those first eleven have caused a lot of debate over the years. In fact, the next slide is going to kind of give you the line of where I am going to take you today. You might not be aware of this, but there is a Noah controversy. You and I, when we hear the story of a great flood, the first thing that comes to our mind—when we think of the whopper of all whoppers—we think of Noah and the Ark, but if we lived in Abraham’s time or especially before, the name Noah probably would not have come up. In fact, if we grew up with Abraham, the story we would have most likely known about was the story—I am going to butcher this name—of Utnapishtim.

You are familiar with Utnapishtim aren’t you? And you are familiar with the god Enlil. I am sure you are familiar with Enlil. And you would have been very aware of a storybook that was read by children and adults alike called the Epic of Gilgamesh. And in the eleventh tablet of the Epic of Gilgamesh, we have the story of Utnapishtim and the god Enlil. And just so that you would know about that story a little bit, knowing that that would have been the predominant story that you would have understood anytime you thought about a flood, this is how the story went down. So, this god Enlil was the god of thunder and rain and all that and he was not a happy camper (kind of temperamental) as thunder gods can be. And for no clear reason, except to mess around with some of the other gods in his discontent, he made the decision that he was going to wipe out the earth with a great flood. And one of the other gods, a goddess in fact, did not like that this was going to happen and thought that it was unfair, unjust, and so she sent a message to Utnapishtim that this flood was going to come at the hand and the wrath of Enlil. And so Utnapishtim got to work, and he built a vessel (a strange vessel), a cube, but he used some of the similar materials that we saw in the Ark, and he made this massive structure (if in fact you do the math, it is probably at least twice, if not much larger, than the actual Ark) this massive cube that he made hoping that it would float, and he got it done on time.

The rain didn’t come down for forty days, it came down just for seven, but it flooded everything out, and the only survivor was Utnapishtim. And when Enlil came around and saw that some human beings had survived, he was very upset because he intended to wipe out everybody to show his wrath and his anger to the world and to show that he was upset to all the gods in heaven. Well, Utnapishtim obviously saved his own life, the life of his family, the life of his personal animals because those are the animals that he saved—not the rest of the animals of the world. And he took some carpenters along because he didn’t know how to build stuff and once you are starting over you have got to build stuff, and so he brought some carpenters along. In honor of his faithfulness (in light of this word from the goddess) he was given divinity. And so, he became a god, he became one of the gods, he got to reside in heaven, if you will, because of his faithfulness…interesting story.

If you grew up in Sumer, which is present day Iraq, and you grew up with Abraham in what is present day Baghdad that would have been the story that you would have known very, very well. It is because that story exists and other cultures have their own flood stories as well that some scholars look at the story of Noah and the Ark, and they think, ‘well, gee, how should we really interpret this thing? You know, our Enlightenment and post-Enlightenment perspective says it is in black and white, and if it says that is what happened, then that is exactly what happened. There is no way around it.’ Well, what if the first people who shared this story with each other and what if the early writers of this word, what if when they approached the Bible, they didn’t approach it the way we do? What if they didn’t approach the Bible, the Word of God, as a literal, this is exactly how it happened book that our post- Enlightenment eyes are framed to do? How would that change us? And also, some of the things that some of the challengers of this story are bringing out are some of the issues with the story like ok is this really a big enough boat to handle all of the creatures of creation…can they really, really fit?

Some have really tried to make a case that there weren’t as many animals back then as there are now because they got together and hooked up, and now, we have all kinds of varieties and that kind of thing. And so that is kind of there, but you are talking ten months of time! How do you feed all the animals of the world? How do you store all the food? Did they eat fish, because the fish didn’t die? The fish lived on just fine. How do you do that? And what about—it is kind of unpleasant—but all the excrement? What are you going to do with all that ‘bleep?’ Are you going to throw it out the eighteen inch window at the top? Did they have a conveyor belt system? How did it work? And so they look at that and think, ‘I am just not sure about that.’ Would you really take that literally? Is that how we should take it? Is that how they took it around their campfires and around their dinner tables? Did they think about it that way?

And there are other issues too that academics look at, and they challenge somewhat. Like they know that forty days and forty nights is a proverbial statement in Jewish culture. It was like saying (and you see it in many accounts in the Bible), forty days and forty nights was saying a long time, but it probably was not meant to be taken literally. It is just a long time. It is how they thought about things. Then, there is the issue of the rain itself, and how it all came down. Now, the New Living Translation and most modern translations, just simply talk about it as--there is the sky and the rain came down from the sky and you are good to go. But there is another word that is used. If you go to the New King James Bible, for instance, and they talk about the firmament—that the rain came down from the firmament. And so, when we think about firmament, we think, ‘well they are talking about sky or they are talking about the starry host and all that stuff,’ but if we go back to the original word, which the New American Standard version got right (it is one of the most academic and precise versions that is out there), both in the creation story and in the Noah account, they use a different word for sky: they use the word dome.

Now, I am going to butcher this a little bit, but broad stroke version is that the way the ancient people saw the world was that we kind of lived in this bubble, you know sort of like a snow globe, and there was water--not all inside, but outside, surrounding us. There was water below and there was water above, and above us was this massive dome called the firmament or called the sky. And then when it rained it was because God was opening up the floodgates of heaven. That is how they thought back then. They didn’t know any better. And so, kind of what these questions are asking us now is how we make sense of this and do we have to believe like they did in order to believe the story. How many of you believe that the sun revolves around the earth? None! Nobody does. Do you get mad at, do any of you hold a grudge against the earliest people in the Bible, actually, all the people in the Bible, do you hold them accountable and are you angry at them that they believed with everything in them that the sun revolved around the earth and not the other way around?... no, of course not. Do you get angry at them because they believed we lived in a dome and that God opened up the gates of heaven and there you go? No, you don’t hold it against them because you understand that it is the best that they could do given their time.

But we live in the age of Doppler radar, right? We know within minutes, you know, when rain is going to hit Napa and when it is going to move on to Valeo, and so on and so forth. I mean it is that precise, and we know when it is coming hundreds of miles off shore and we can look thousands of miles because of satellite stuff and our ability to understand temperatures and all that. We know how the whole thing is brewing. We know that hurricanes are lining up one after the other in hurricane season because we have cameras up there that are seeing them start to form, and we can gauge temperature in the water and so forth—we do not live back then. So, it would be inappropriate for us to become primitive in the sense of looking at the world the same way they did in that kind of a literalness because we know different, you know what I mean? We know different. And so really the bottom line is that the literalness of the story really isn’t the most important thing to begin with anyway.”

A few editorial reflective thoughts by Darrel Falk: The sermon continues, of course, and you can download it at the above link. What is "the most important thing" to which Pastor Shaw refers as the audio clip draws to a close? Regardless of whether you think it is historical or not, what is the message that God wants to communicate to us through this story? Consider reading Genesis 9 right now. What are the parallels in this "recreation"account to the original creation account? What does God want us to see in making those parallels? What about the rainbow? What does it symbolize for you? Can you sense God's love for all of creation (not just humankind) as this story draws to a close? Why does the story of Noah himself, however, not have a happier ending? Have we seen the theme of nakedness and the need to cover up nakedness in an earlier scriptural passage? Why do you think the story of Noah draws us back to this point (nakedness and shame), just like the story Adam and Eve does? What brought on shame for them? What brings on shame for us? Do you see that God is wanting us to think deeply about this story and its meaning? What is another example of the need to cover up? (Hint: think Moses.) What difference does the coming of Jesus make to all of this? (Hint: see II Corinthians 3:12-18.) Do you see the rainbow?]]> Sat, 12 Nov 11 04:00:15 -0800 Pete Shaw Series: Understanding Evolution http://biologos.org/blog/series/understanding-evolution?utm_source=RSS_Feed&utm_medium=RSS&utm_campaign=RSS_Syndication http://biologos.org/blog/series/understanding-evolution?utm_source=RSS_Feed&utm_medium=RSS&utm_campaign=RSS_Syndication This blog series by Dennis Venema undertakes the task of clarifying numerous aspects of evolution that often become misconstrued by Christians. He first discusses the idea of speciation in a population over time, later applying it to the speciation process that occurred among hominids (human ancestors) which led to modern humans. He continues to support this idea by exploring so called “Mitochondrial Eve,”“Y Chromosome Adam” and other compositional clues of the human genome. Geographic isolation and reproductive barriers

As we have seen, speciation (the events that lead to reproductive isolation between populations of organisms) can be a prolonged and complex process. Populations can become isolated geographically (e.g. through migration) and begin to accumulate genetic differences that may raise a barrier to reproduction between them. This barrier may only be a partial barrier, however. The stickleback populations we discussed previously are an example: the first event leading to speciation was physical separation when some marine fish colonized new freshwater habitats. Even after significant differences accumulated between the marine and freshwater forms, a second wave of colonization of fresh water by the marine form brought the two groups into contact again, leading to some genetic exchange even as the two groups remained largely distinct. At the point of the second colonization, whether one or two species is/are present is a point of discussion: the case can be made for either. A scientist arguing for one species would point out that the two groups can still produce fertile offspring, whereas a colleague might argue for two based the distinct characteristics and ecological niches of the two populations, as well as the observation that the hybrids resulting from interbreeding are not as well adapted to either niche. The point is clear: speciation, as a slow process, is a gradient, and a clear line of demarcation cannot be drawn on a gradient. To return to our flip-book analogy, every adjacent page is only slightly different from the pages on either side. If we compare widely separated pages, the differences are clear. The point is that there is no single page in between them that we can identify as the point where the images “became different.”

While this discussion might seem a little academic and uninteresting (perhaps because one might discount such events as mere ‘microevolution’ of sticklebacks), we have recently learned that similar events shaped human speciation. As far as we can tell, sticklebacks are not aware of, nor concerned about, the theological implications of how they came to be, but we certainly are for our own species (and perhaps even for sticklebacks). What was once an area of interest mainly for specialists is about to become a topic of intense discussion among evangelicals: we have only recently learned that a portion of the lineage leading to modern humans interbred with other hominid species they encountered as they migrated out of Africa ~50,000 years ago. In order to explain what happened, let’s pick up the tale at an earlier point, around 450,000 years earlier.

Out of Africa, twice over

Somewhere between 500,000 and 300,000 years ago, the ancestors of the Neanderthals (Homo neanderthalensis) left Africa and migrated into the Middle East region, and from there on to Europe and parts of Asia. (Recall that human ancestors, at this point, are all still in Africa, and will stay put until around 50,000 years ago). Neanderthals persisted in the Middle East and Europe until ~30,000 years ago, meaning there was a time where the humans leaving Africa about 50,000 years ago could have interbred with them before they went extinct. This remained an open question until techniques improved to recover and sequence ancient DNA. It is now possible to obtain and sequence DNA from Neanderthal remains, and the complete genome sequence of Neanderthals was published in early 2010. The results were fascinating: DNA sequence comparisons between the two species indicates that modern, non-African humans have about 1-4% Neanderthal DNA in their genomes. This variation, however, is not present in sub-Saharan Africans, since they are descended from humans that did not leave Africa and and thereby, because of geographical separation, never had the opportunity to interbreed with Neanderthals. We also know that the group that left Africa went through a reduction in population size to a about 1200 individuals (a genetic bottleneck), whereas those that stayed behind maintained a larger population size (about 6000) over the same period.

New details

In addition to this information, we have recently discovered a new hominid species from Asia, as Darrel Falk recently highlighted here on BioLogos. This species, named the “Denisovans” is known to us only from a few bone fragments and one molar, but - wonder of wonders in this age of paleogenomics - this was enough for us to determine its complete genome sequence. The results were, again, fascinating: the Denisovans are relative of Neanderthals that split off from them after their common ancestor left Africa. The Neanderthals went west to Europe, and the Denisovans colonized Asia (and evidence suggests they were quite widespread). Even more interesting is that comparing Denisovan and human DNA indicates that some humans (modern Melanesians) have about 5% Denisovan DNA in their genomes. This variation is not found in Europeans or Africans.

Putting the story together

Assembling all of this information reveals the following tale: the common ancestor of Neanderthals and Denisovans migrated from Africa to the Middle East between 500,000 and 300,000 years ago, leaving a population behind that would eventually become modern humans (at around 200,000 years ago). In the Middle East, the populations destined to become Neanderthals and Denisovans part ways, with their differences accumulating over the next several hundred thousand years to make them distinct species. When a population of modern humans leave Africa around 50,000 years ago, they encounter, and breed with, Neanderthals shortly after. This genetic exchange is small, since there are partial reproductive barriers in place, but a small fraction of Neanderthal DNA becomes established in this lineage. Groups from this population then part ways, with some migrating into Europe and others into Asia. This latter group then encounters the Denisovan hominids, interbreeds with them, and a fraction of Denisovan DNA takes hold as a result. This population goes on to colonize southeast Asia, Oceania and Australia, where we see this variation today in Melanesians. Modern humans thus have different evolutionary trajectories: Melanesians have both Neanderthals and Denisovans in their lineage, Europeans have Neanderthals, and Africans have neither.

New data, new questions

Even as I stand amazed in what God has revealed to us about our origins through science, I know that this new information will be difficult for some within the evangelical community to accept. Moreover, it is almost certain that some Christian groups, unfortunately, will misrepresent this data to their constituents (whether intentionally or not), and thus spread confusion that hinders the needed theological conversation. Still, I have reason for hope: God has seen it fit to reveal this information to us, and that suggests that He believes the evangelical Christian community is ready for this conversation to happen. As Darrel mentioned at the end of his recent piece, we at BioLogos want to assist our evangelical sisters and brothers in this conversation in any way we can, in full confidence that it can be done in an edifying way:

BioLogos exists to help Christians think carefully about the ramifications of these new data in light of long-standing traditional ways of viewing human creation. We have some re-thinking to do, but it can be done and will be done within the context of a Christian faith that is fully orthodox and thoroughly evangelical. Any time we draw closer to truth, to God’s truth, we have nothing to fear. There is still much to learn, but we can look back at what we have learned with awe—absolute awe.

Many scientists think that evolution is a directionless process, one in which humans are merely an accidental byproduct. In a recent episode of the award-winning radio program “To the Best of Our Knowledge” (produced by Wisconsin Public Radio, and reposted above, with permission), however, esteemed paleontologist Simon Conway Morris of Cambridge University explains a different view of evolution. Conway Morris has catalogued plentiful examples of evolutionary convergence, in which different organisms arrive at the same function through different evolutionary pathways, including the trait of intelligence. He examines the ability of the octopus to gaze, learn and play, and compares it to the intelligent behaviors of dolphins and the tool making ability of certain crows. Given enough time and resources, he says, every ecological niche will be filled up by some kind of life form. One of these niches is that for highly intelligent life, a niche occupied by us, Homo sapiens. If the tape was rewound and evolution started over from scratch, Conway Morris says, the evolutionary details would be different, but the end result would be similar: a species characterized by intelligence and complex civilization.

While several esteemed scientists, including atheist Richard Dawkins, and Brown University cell biologist, Kenneth Miller, agree with Simon Conway Morris, most (according to Dawkins) do not accept that evolution can have this sort of directionality. Sean Carroll, leading evolutionary biologist and Vice-President of the Howard Hughes Medical Institute, says that animals merely “exploit what’s available,” with no necessary end. Little, he believes, is inevitable. “With a few other rolls of the dice”, he says, evolution would have resulted in a significantly different assortment of organisms. Noted philosopher of science, Daniel Dennett, agrees with Carroll. Just as the origin and wide-spread diversity of creatures like marsupials (mammals with a pouch) was not inevitable, he says, so the evolution of intelligent human-like beings was not inevitable either. Dennett goes on to say:

The idea that this whole great universe was in some sense designed or intended for us strikes me as just bizarrely self-involved (chuckles)—one of the most stunningly narcissistic visions that I’ve ever encountered. It seems unlikely, don’t you think?

In complete contrast Conway Morris says:

The universe from a theistic viewpoint, from a Christian viewpoint, is utterly contingent. It needn’t exist at all, more particularly it could be anything which God so chose. Science is an open-ended adventure; we don’t know where it’s going to end. People who think religion is simply a set of answers to keep you comfortable are, I’m afraid, sadly mistaken—it is an open-ended adventure. We don’t know, really, what the nature of the universe is. We don’t know why we have our moral, ethical, intellectual and poetic capacities. I know they come from an evolutionary basis, I have no quarrel with that. But so far as I’m concerned, we are going on to completely new territory and my view would be that in fact the religious instincts and the religious teachings actually tell us something real about the world. They’re not simply fairy stories.

So is the near-certainty of human life front-loaded from the beginning? Was it predetermined from the Big Bang that human beings would eventually arise? Was it predetermined that God’s natural activity—that activity which upholds the universe and maintains all that is within it—would be sufficient for the eventual development of humans? Alternatively, was supernatural activity required for the creation of the human body? Does the Bible dictate one way or the other? Is it somehow less God’s creation if it took place through God’s natural activity? Is it somehow more God’s creation if supernatural activity was required? These are questions for theologians. Science is taking us up to edge as Conway Morris brilliantly shows. There, we meet the theologians, and there, we begin the journey’s next phase.

I encourage you to listen to the above recording. The deeper we explore creation, the more we see and appreciate its beauty. So also, and even more significant, the deeper we embed ourselves in God's written and Living Word, the more confident we become of “Romans 8:26-39”. We are loved. More than we can possibly imagine, we are deeply embedded in the love of God. This, truly, is "Life's Solution."

This subtle but extremely important point was missed entirely in the NPR story. The conversation regarding the historicity of Adam and Eve, described so clearly in the cover story of the June issue of Christianity Today, continues in an unlikely place—at National Public Radio. If you haven’t already heard it, you’ll want to listen to this story. BioLogos Senior Fellow Dennis Venema does a beautiful job summarizing the genetic data in a non-technical way, and Karl Giberson addresses the serious danger to the Church if we ignore this data. While we at BioLogos appreciate many aspects of the story, we need to make one all-important clarification: the debate over the historicity of Adam and Eve is primarily a theological debate, one that is more complex than the story lets on. All science can say is that there was never a time when only two people existed on the earth: it is silent on whether or not God began a special relationship with a historical couple at some point in the past. This subtle but extremely important point was missed entirely in the NPR story. It is a consideration that we raise repeatedly at BioLogos. See, for example this article by Daniel Harrell and this series by Denis Alexander.

Evangelical Christians have long suspected there are allegorical components to the Genesis story—a talking snake, for example—but as to whether Adam and Eve were not real people, there has been much more hesitancy--and for theologically important reasons. The science itself is silent—the most it can say is that there were never just two individuals who were the sole genetic progenitors of the entire human race. Several independent lines of genetic evidence unambiguously point to this conclusion. Science also make it very clear that humans developed through an evolutionary process. As Christians, we interpret all this in light of our belief in God as Creator.

It is important for Evangelicals to know that science is silent on the historicity of two people named Adam and Eve, just as it is silent on the existence of persons named Abraham, Isaac, and Moses. Adam and Eve may well have been two real people, who through the grace of God entered into a paradisiacal relationship with him, until—tragedy of tragedies— they allowed their own self-centered desires to reign in their hearts, instead of their love for God. Although genetics convincingly shows that there was never a time when there were just two persons, the Bible itself may even provide hints of the existence of other people—likely we’ve all wondered about those hints since we were children. “Did Cain marry his sister?” we want to know. “Who were the people that Cain was afraid of as he wandered the earth after killing Abel? If they were his brothers or nephews, why didn’t the author refer to them that way?” The author doesn’t seem to be as puzzled by this as we are. We’ve always known about those little pointers—in fact, ancient interpreters wrestled with them too, long before Darwin or modern genetics appeared on the scene. So it ought not to necessarily surprise us for genetics to come along and confirm that, sure enough, there were others around at the time of Adam and Eve.

The NPR story, as much as we appreciate it, implies that, according to science, there are only two options for Christians—dismiss the conclusions of science, or dismiss the notion of a historical couple named Adam and Eve. This is simply not the whole story. Any dismissal of a historical couple, who entered into relationship with God only to sin and break that relationship, is going to have to come from theology. There is no scientific reason to upset that theological apple cart. Indeed as scientists, we must respect the theological diversity of Evangelicalism.

Science is an amazing tool that gives insight into our world, one which is so effective that it is allows us to become virtually certain about some things. The earth does revolve around the sun. The universe was created over 14 billion years ago. All species came about through a gradual process that included natural selection, genetic drift and sexual selection. Christians should see all of this as the product of God’s masterful plan and ongoing activity. Christians should also see that science is silent on the existence of a specific first couple who enjoyed a special relationship with God. Exploring that is beyond the purview of science.

]]> Wed, 10 Aug 11 04:59:41 -0700 Darrel Falk, Applegate, Kathryn BioLogos and the June 2011 “Christianity Today” Editorial http://biologos.org/blog/biologos-and-the-june-2011-christianity-today-editorial?utm_source=RSS_Feed&utm_medium=RSS&utm_campaign=RSS_Syndication http://biologos.org/blog/biologos-and-the-june-2011-christianity-today-editorial?utm_source=RSS_Feed&utm_medium=RSS&utm_campaign=RSS_Syndication The editorial, in other words, has shown that in their view mainstream evangelical Christianity and mainstream science can co-exist in harmony. There are still many details to be worked out and much conversation lies ahead, but there is reason for optimism. In a one page editorial entitled "No Adam, No Eve, No Gospel" (Christianity Today, June 2011, p. 61), Christianity Today (C.T.) draws the line. It is foundational to hold onto the view, the editorial states, that there were two real people named Adam and Eve. Given what else is said in the editorial, regardless of whether they are correct on the historicity question, I heartily applaud the article.

As I wrote last week, the data are clear that humans have been created through an evolutionary process and there was never a time when there was a single first couple, two people who were the progenitors of the entire human race. Within that framework, BioLogos does not take a position on the existence, in history, of two unique individuals, Adam and Eve. This is a theological question, not a scientific one. We recognize that now that the scientific consensus is clear, having become substantiated even further through genetics, there will be many fine theological minds on both sides of the historicity question. Our task is to help the Church come to appreciate that mainstream science and Christianity can co-exist in harmony. We’re happy to stand back and watch as the theologians work through the historicity question. Indeed, some of that conversation may well take place on these pages.

What pleases me most about the C.T. editorial is that it shows the willingness of the C.T. editorial staff to pay close attention to scientific consensus. Look at what they say:

Sometimes, Christian ways of thinking must adjust. Two famous names—Copernicus and Galileo—tell that tale. Other times Christian thinkers adopt some of what scientific research suggests, but hold firm on key aspects of biblical knowledge. The name B.B. Warfield tells that tale…

As the article goes on, the editors also make this statement:

Now we come to another great moment of tension between Christian readings of Scripture and science…

Christians have already drawn the line: there must be an original pair of humans endowed with soul—that is, the spiritual capacity to relate to God in the special way Genesis describes.

Having explained why the line must be drawn at a first couple, the editorial goes on to briefly discuss ways of bringing harmony between the science and traditional Christianity:

Hebrew thought offers one clue to resolving this tension: The corporate nature of humanity. Scripture often calls groups of people by the name of their historical head. Israel is an obvious example. So are Canaan and Cush.

At times, Scripture also holds groups of people morally responsible for the actions of some of their members.

Thus some have suggested—as does John Collins in “Did Adam and Eve Really Exist?” (Crossway, 2011)—that if both biblical and scientific clues suggest a larger population contemporary with Adam and Eve (Whom did Cain marry? Whom did God protect him from?), we can still conceive of Adam and Eve as leaders of that original population. That suggestion has the virtue of embracing both a prehistoric couple and a prehistoric population.

Finally, and all importantly:

At this juncture we counsel patience. We don’t need another fundamentalist reaction against science. We need instead a positive interdisciplinary engagement that recognizes the good will of all involved and that creative thinking takes time. In the long run, it may be the humility of our scholars as much as their technical expertise that will bring us to deeper knowledge of the truth.

The C.T. editorial, in other words, has shown that in their view mainstream evangelical Christianity and mainstream science can co-exist in harmony. There are still many details to be worked out and much conversation lies ahead, but there is reason for optimism. The findings of science and the evangelical approach to Christianity need not be at dead end anymore, and we are thankful that the editorial staff of “Christianity Today” is clearing away the barriers and beginning to pave the way.

As we move forward, the conversation ought to focus on matters about which we can all agree. This is part of the reason that BioLogos has begun a Saturday sermon series, which currently focuses on a set of sermons delivered by Pastor Tim Keller of Redeemer Presbyterian Church in New York City. I have now listened to the second sermon in this series four times and every time I hear it, I glean some new truth that leaves me in complete awe of our Creator and the never-ending depth of a theology thoroughly grounded in Genesis. Each week we post a four minute excerpt, a brief summary, and then a link to download the entire sermon. We are encouraging people to come back after listening to the whole sermon to “talk” about it if they so desire. So far, it has largely been the atheists who have been chomping at the bit to enter into conversation. That’s not what we want though, especially when I suspect that they have not even listened to the sermon. We hope that a large group of fellow believers will listen to these sermons together as we are all drawn into a spirit of celebration for the beauty of the creation story as fully revealed in Genesis, Romans and Revelation.

The reason that I am advocating Pastor Keller’s messages as the rallying point around which we can all gather is that as one listens to what he has to say, there is very little with which any of us Christians would disagree, regardless of our perspective on details. As I listened again to last Saturday’s sermon, The First Word, I thought to myself that if I were a young earth creationist, I could embrace almost everything he said and grow richly closer to God in the process. However, that would be equally true if I was a Reasons to Believe, old earth creationist, or a William Dembski I.D. theorist, or, of course, a BioLogos evolutionary creationist. The fact is that we are all one. We can all rally around the Word as expounded by pastors such as Dr. Keller. Sure we’ll look at some parts differently—but when we are all hearing the Word together, we can all celebrate its message as it speaks to the heart and soul of who we are as Christians. As we do that—together—we will all, with one voice be able to cry out in unison—“Christ in you—the hope of Glory!” The atheists will look on and wonder what is happening, but what they will see as we all celebrate and worship together is the radiant face of Jesus—the Body of Christ in unison celebrating the beauty of the Creation story as it is completely fulfilled in our Lord.

Editor's Note: Please see Darrel's follow up comment below (#62248) for some clarification on the piece and BioLogos' position on Adam and Eve. Also the first two sentences of the second paragraph have been modified slightly to ensure that the BioLogos position is clear.

For the Christian, the answer is complex. In part, it is a reflection of being created in the image of God. But does the science of human evolution pose a threat to that uniqueness?

-->

Today we post the final installment in our four-part "Distinctions" series. This video was directed by Loretta Cooper, President of Clarity Media Strategies and was scripted by Loretta Cooper and BioLogos Program Director, Kathryn Applegate.

Narrator: What does it mean to be human? For the Christian, the answer is complex. In part, it is a reflection of being created in the image of God with free will and common values. But does the science of human evolution pose a threat to that uniqueness?

Lee Strobel: But in the last 150 years, science has failed to substantiate Darwin’s claims of macro-evolution.

Mike Riddle: The Bible teaches that God created all creatures after their kind; there was not one common ancestor everything evolved from.

Ken Ham: You know, through this nation, whole generations of young people are being taught in the public schools that there is no God, life evolved by natural processes, and that very much determines their morality, how they view themselves, their purpose and, meaning in life, and so on.

Narrator: Not all Christians view evolutionary science as a threat to their faith, and not all scientists see human evolution as a strictly materialistic process. There are those in both communities who believe the explanation is much more complex, including Dr. Rick Potts. Dr. Potts is one of the world’s leading paleoanthropologists, and the curator of (anthropology at) Smithsonian’s Museum of Natural History.

Rick Potts: What we’ve found is that part of our message is that an aspect of being human has been the process of becoming human that scientists have been able to uncover, and that includes the amazingness, if you will, of the fact that human beings today are connected to all other living creatures. There is this vast kinship that all creatures share on earth, and that is a beautiful thing.

Narrator: But the idea of common ancestry is anything but beautiful to many conservative Christians. It’s a prospect that has caused consternation among American evangelicals dating back at least to the Scopes Trial in 1925. Others, however, insist that there is nothing in common ancestry that should alarm those who have observed nature and who study the character of creator God.

Denis Alexander: When we talk about common ancestry, we don’t mean we are descended from the apes, we mean that we shared a common ancestor with the apes about six million years ago, plus or minus a little bit. And so the apes have been evolving their own particular way and we have been evolving our way. But the fact that we are all linked up in this evolutionary, historical way, I think is a just wonderful drama, a theater. And to me, anyway, I find it a privilege that I should be connected up to all these wonderful creatures.

Greg Boyd: And on the one hand I want to fully acknowledge that we human beings are in a class by ourselves, and that we are radically unique in God’s plan because we are to have dominion and to be the stewards of the planet and things of that sort. So I want to totally affirm that. On the other hand, if you totally separate humans from the rest of the animal kingdom, then you miss the beautiful continuity that is there, and part of the fear, I think, for people in thinking that we in any way came from apes is that it undignifies us. Well, it doesn’t. On the other hand, if our dignity has to be all at their expense then we have all the dignity and they have none, if we are in competition with them, and then we exploit them. There is a dignity to human beings that animals don’t have, but on the other hand, there is a worth and a value there that we need to respect.

Narrator: Any honest dialogue about the origins of humanity must acknowledge that some scientists and some Christians will never find common ground on this issue. But for those willing to engage in the conversation with prayerful hearts and open minds, the dialogue can lead us to glimpses of our Creator that inspire awe and worship.

We are pleased that a matter deemed so important by us is beginning to play a prominent role in the discussion for the Church as a whole.

As detailed extensively on these pages over the past two years, there is now little doubt that God has created all life forms, including human beings, through an evolutionary process. God could have created in an instant. After all, in the supreme divine act of all time Jesus was raised from the dead—in an instant. However, it now seems certain that this is not the way He chose to create the human body. God’s process was gradual, not instantaneous.

We are fully aware that interpretation of scientific data changes and this fact causes some to be skeptical about the scientific consensus regarding human creation. True, scientific revolutions do occur. However, the data with regard to human creation has been accumulating for 150 years, and the conclusions have been substantiated through a wide variety of scientific disciplines. Astronomy shows that the universe is billions of years old. Geology independently shows that the earth, though a little younger, is also billions of years old. Paleontology poignantly lays out the parade of created life forms and graphically documents the species-changes over hundreds of millions of years. Comparative anatomy and developmental biology show feature after feature in living bodies, each with its distinctive trademark pointing to gradual alteration from that which came before. And, with the sequencing of the human genome, genetics provides the final confirmatory lynch pin. Creation through a gradual process is not a hypothesis that emerges from a peripheral scientific sub-discipline. To show it wrong would involve overturning principles that independently lie at the very core of the findings of most of the natural science disciplines. True, they all together cry out in unison with a loud voice—“Created!” However, they also, in a subtle, but persuasive whisper, add the all-important qualifying phrase—“…slowly and not in an instant!”

The Christianity Today cover story is important because it engages the Church in one of the most important questions of all: was there a historical Adam and Eve? There has been much discussion of this point on these pages and although we strongly encourage ongoing discussion, BioLogos does not take a position on the issue. Denis Alexander, Director of the Faraday Institute and a frequent contributor to the BioLogos conversation says ‘yes’ in this BioLogos article, and Tim Keller, pastor of Redeemer Presbyterian Church in New York City affirms it in this one. Denis Lamoureux and Peter Enns believe otherwise and have expressed their views here and here, for example. The scientific data are silent on the possibility of a federal headship—two unique individuals singled out by God from all others to enter into relationship with him and to bear his image. Similarly, science is silent on the veracity of the alternative possibility— that the story of Adam and Eve is not a story of two unique individuals. According to this latter view, the story of Adam and Eve is in a very real sense the story of all humankind—we have all sinned and we are all in need of redemption.

These are theological questions, not scientific ones. Science makes it abundantly clear, we believe, that God has created through an evolutionary process and that there was never a time when there were just two individuals on earth. It goes no further though. Beyond that, we are in a different realm, one deeply steeped in the traditions and creeds of the church, and in theology, biblical scholarship, and philosophy.

Although The BioLogos Forum has raised the issue and encouraged discussion, we also urge caution. The “Federal Headship” model that accepts the scientific findings while at the same time holding to the historicity of a real first couple has not yet been carefully worked out by theologians. The reason that we haven’t had many articles of that sort is because we haven’t been able to identify theologians who are looking at the question from that perspective. In general, our experience has been that theologians are in one of two camps. Either they work within the framework of a non-historical Adam and Eve or they believe the scientific conclusions will eventually prove to be deeply flawed and humans were not created through an evolutionary process after all.

The purpose of BioLogos is to show that there can be harmony between mainstream science and evangelical Christianity. We are in complete agreement with Richard Ostling (the author of the aforementioned article) and the Editors of Christianity Today that working through the historicity question is of the utmost importance to the Evangelical Church. Within the framework outlined above, it boils down to theology not science, and we urge the Church to reserve judgment for a while. Let’s keep both possibilities before us. Here’s hoping that some of our greatest theological minds will work on the question of what a model based on “Federal Headship” would look like. Here’s also hoping that some of our finest theologians will continue to work on how the view of a non-historical Adam would address some of the issues that puzzle and concern most evangelicals. Communication is key. This must move beyond theologians speaking to each other in language that is not readily accessible to the rest of us. Let’s figure out pastorally-responsible ways of putting the issues before the Church in a manner which is respectful of all views, while not shying away from the challenges that lay before us.

This is an exciting time for the Church because there is much interesting work to be done. Personally, I reserve judgment and I urge that all of us proceed with caution. Let’s see what emerges. Let’s see what our theologians and philosophers come up with, especially those who hold to a historical Adam and Eve. The Church is 2,000 years old. It has been guided by some of the sharpest minds that have ever lived and it has done so under the guiding wisdom of Emmanuel—God with us. This is God’s Church and we must proceed prayerfully, lovingly, and solemnly. We must listen intently to the wise voices of our deep past while following the Spirit’s guidance into a future where we have not yet been. We are not alone though. We are surrounded by a great cloud of witnesses whose lives and work remind us of the faithfulness of God through the millennia. This is still God’s Church and we are still God’s people. We are not alone. Emmanuel—God is with us!
