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.

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.

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.
