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.

Denis Alexander begins this five part series by discussing both what a model is and whether it is appropriate to use one when building a bridge between scientific truths and theological truths. Providing evolutionary facts about the origins of humans as well as discussing the origin and meaning of Adam in Genesis, he constructs what he calls a Retelling model and a Homo divinus model. Both approaches, he concludes, “suggest that human evolution per se is irrelevant to the theological understanding of humankind made in the image of God.”

The tenth anniversary of the human genome has been marked by some striking new genetic insights into human evolution and diversity. Do these new discoveries have any significance for the dialogue between science and religion?

Is the human race descended from one ancestral pair in the recent past? Are we, as C.S. Lewis puts it in his Chronicles of Narnia, the “sons of Adam and daughters of Eve”?

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. But does the science of human evolution pose a threat to that uniqueness?

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!”

Science and Religion scholar Denis Alexander presents two models for relating Adam and Eve with the findings of contemporary anthropology. This essay was presented at the November 2010 Theology of Celebration Workshop

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.

In this brief video “Conversation” Denis Alexander explains that common ancestry does not mean that we are descended from apes, rather, it means that we last shared a common ancestor with them roughly 6 million years ago.
