This week I am reading Nicholas Wade’s Before The Dawn. It’s a review of recent developments in archeology, particularly the important contribution that biogenetics is making to our knowledge of our ancient ancestors.
For instance, tracking of the Y chromosome in men indicates that we are all descended from one man. And tracking of mitochondria in women indicates that women are all descended from the same woman. And it seems likely that all people except those in Africa are descended from a band of hunter-gatherers that crossed the southern end of the Red Sea from Africa to Arabia about 50,000 years ago.
It is intriguing that the Biblical speculation of Adam and Eve, and even the Mosaic Red Sea crossing receive echoes in the latest science.
Nicholas Wade is a science correspondent for The New York Times and so it is significant that he tells his readers that, like it or not, ancient man engaged in constant warfare. That behavior, of course, is shared by our great ape cousins. Male chimpanzees frequently engage in border raids on the territory of neighboring troops. They do it for a practical reason. A bigger territory means more food, and more food means more baby chimps making it to adulthood.
But over the years, humans have become more “gracile,” meaning that our skulls and skeletons have become less robust. In other words, we have become more oriented towards cooperation and less to competition and conflict.
But here’s an interesting speculation. The big problem for humans is to develop the trust circle for cooperation, and particularly cooperation outside kinship. How do you control and sanction the freeloader? The human solution, he suggests, is religion.
Maybe that explains why the rising European bourgeoisie of the last millennium developed their own religion, Protestant Christianity, to define their trust network. And maybe that explains the explosive growth of evangelical Christianity in the emerging economies of the world. The big problem for the people in the huge new cities is to establish trust networks to replace the old kin-based trust in the village.
