Not a religious point of view....

Why do we believe in God? from The Guardian

"Richard Dawkins, our best-known Darwinist and a ferocious critic of organised religion, notes that religion seems to be, on the face of it, a cost rather than a benefit: "Religious behaviour in bipedal apes occupies large quantities of time. It devours huge resources. A medieval cathedral consumed hundreds of man-centuries in its building. Sacred music and devotional paintings largely monopolised medieval and Renaissance talent. Thousands, perhaps millions, of people have died, often accepting torture first, for loyalty to one religion against a scarcely distinguishable alternative. Devout people have died for their gods, killed for them, fasted for them, endured whipping, undertaken a lifetime of celibacy, and sworn themselves to asocial silence for the sake of religion."
It seems at first glance as if Dawkins is arguing that religion is an evolutionary disaster area. Religious belief, it seems, would be unlikely, on its own merits, to have slipped through the net of natural selection. But maybe that interpretation of what Dawkins is saying neglects some of the further benefits that religion might well offer in the human quest for survival and security.
In his book Darwin's Cathedral, David Sloan Wilson, professor of biology and anthropology at Binghamton University in New York state, says that religiosity emerged as a "useful" genetic trait because it had the effect of making social groups more unified. The communal nature of religion certainly would have given groups of hunter-gatherers a stronger sense of togetherness. This produced a leaner, meaner survival machine, a group that was more likely to be able to defend a waterhole, or kill more antelope, or capture their opponents' daughters. The better the religion was at producing an organised and disciplined group, the more effective they would have been at staying alive, and hence at passing their genes on to the next generation. This is what we mean by "natural selection": adaptations which help survival and reproduction get passed down through the genes. Taking into account the additional suggestion, from various studies of twins, that we may have an inherited disposition towards religious belief, is there any evidence that the Divine Idea might be carried in our genes?"
