The God gene?

The idea that religion might be connected to the Darwinian ethos of natural selection is either liberating or blasphemous, depending on your point of view. But social scientists have a job to do, and as you can see in this New York Times report, they've been busy.

This and other research is pointing to a new perspective on religion, one that seeks to explain why religious behavior has occurred in societies at every stage of development and in every region of the world. Religion has the hallmarks of an evolved behavior, meaning that it exists because it was favored by natural selection. It is universal because it was wired into our neural circuitry before the ancestral human population dispersed from its African homeland.
For atheists, it is not a particularly welcome thought that religion evolved because it conferred essential benefits on early human societies and their successors. If religion is a lifebelt, it is hard to portray it as useless.
For believers, it may seem threatening to think that the mind has been shaped to believe in gods, since the actual existence of the divine may then seem less likely.
But the evolutionary perspective on religion does not necessarily threaten the central position of either side. That religious behavior was favored by natural selection neither proves nor disproves the existence of gods. For believers, if one accepts that evolution has shaped the human body, why not the mind too? What evolution has done is to endow people with a genetic predisposition to learn the religion of their community, just as they are predisposed to learn its language. With both religion and language, it is culture, not genetics, that then supplies the content of what is learned.
