Until the discovery of DNA's double helix by James Watson and Francis Crick, prehistory was entirely the province of paleontologists and archaeologists. "But in the past few years," Nicholas Wade wrote in his 2006 book, "Before the Dawn: Recovering the Lost History of Our Ancestors" (a work praised by Watson himself, among many others), "an extraordinary new archive has become available to those who study human evolution, human nature and history. It is the record encoded in the DNA of the human genome and in the versions of it carried by the world's population."

In the lost history whose DNA-aided recovery Wade chronicles, one of the most interesting chapters covers "gracilization" -- that is, "a worldwide thinning of the human skull" starting around 40,000 years ago. Why was it that, millenniums before the agricultural revolution, our ancestors became progressively lighter-boned and smaller? A crucial clue: The fossil record and contemporary breeding experiments alike confirm that domestication, whether accidental -- as in the evolution of the dog from the wolf -- or deliberate, induces pedomorphism, or the retention of juvenile features into adulthood. "Gracilization . . . occurred because early modern humans were becoming tamer," Wade writes. "And who, exactly, was domesticating them? The answer is obvious: people were domesticating themselves. In each society the violent and aggressive males somehow ended up with a lesser chance of breeding. This process started some 50,000 years ago, and, in [primatologist Richard] Wrangham's view, it is still in full spate."

For a student of ancient mythologies, this reference to human self-domestication -- sine qua non for the sedentary life that began 15,000 years ago -- brings to mind the oldest of all epics, the 5,000-year-old, originally Sumerian "Epic of Gilgamesh," in which the civilized, city-dwelling title character, though he has much to learn from the wild and hairy Enkidu, finally defeats him. Gilgamesh sleeps with any city woman he chooses, when he chooses. Enkidu makes do in the fields with a single woman, and her a prostitute.

Perhaps the "Epic of Gilgamesh" crystallized memories of the long human self-domestication that Wade writes of, but of equal interest is the possibility that rather than merely recalling the change, this and kindred myths may have contributed to it. If such a literary work were recited repeatedly, honored as supreme truth, taught to the young and this over centuries of time -- if, in short, it were turned into sacred scripture, then could it not create social pressure, then behavioral changes and, finally, over a sufficiently lengthy period, even genetic modification?

And setting gracilization aside, can the later scriptures of West Asia -- the Jewish and Christian Bibles and the Koran -- be read as the record of a process of human domestication, a further taming and gentling of mankind over time? In "The Evolution of God," Robert Wright argues laboriously that they can indeed be so read. After a brief and dated discussion of pre-literate religions, he makes a reading of the three mentioned scriptures in the retrospective light of the steadily growing, gradually more peaceful world community to which they seem to lead. Despite the frequent violence of this three-stranded history, Wright discerns a vector tending distinctly toward unity and away from division. Globalization, for him, is the culmination of this process.

Wright never seeks to demonstrate, however, how in actual practice the scriptures were or might have been deployed to this end. Rather than explain epochal social integration by extrinsic human agency, he looks for an intrinsic explanation -- one written into evolution itself, and the more appealing to him, it seems, the more it defies explanation. Thus, he explains, as natural selection begot cultural evolution and cultural evolution begot successively more comprehensive forms of social organization, "there appeared a moral order, linkage between the growth of social organization and progress toward moral truth. It is this moral order that, to the believer, is grounds for suspecting that the system of evolution by natural selection itself demands a special creative explanation. . . . And if the believer . . . decides to call that source 'God,' well, that's the believer's business. After all, physicists got to choose the word 'electron.' "

Wright's title notwithstanding, his God does not evolve. He is rather a constant, the C-factor without which human evolution does not compute. His book, despite many protestations to the contrary along the way, is finally an argument from design for the existence of God, and as such it does not convince.
