Who are we? Where did we come from? How religious identity divides and damns us all.

Charles Darwin's theory of natural selection, now established, is the only workable explanation we have for the remarkable fact of our own existence, the vast diversity of plant and animal life, the compelling illusion of design in nature, and the architecture of the human mind. We are risen apes, not fallen angels. Our different races and ethnicities hide an essential truth: we are all Africans, all siblings, all descendants of a small group of hunter-gatherers who arose in Africa less than 200,000 years ago and conquered the world. There is one universal human nature stemming from our long history as Pleistocene hunter-gatherers. We now know why religion appeared, why particular religious ideas emerged, why they are widespread, why they are recurrent features of human minds and human societies, why they are attractive to human minds, and how and why they are related to survival and deadly violence. What makes us human can also make us religious. Religion is a by-product of cognitive mechanisms that evolved, through natural selection, for other adaptive purposes that were crucial for our survival and reproductive success. Religion's power derives from its ability to utilize these mental mechanisms designed for other tasks: our attachment to parental figures, our wish for help in distress, submission to authority, our sensitivity to hierarchies, our love of kin, and our inclination to see human-like intention as the explanation for any unknown. All individuals are vulnerable to religious beliefs and assuming a religious identity. Religious identity is an accident of geographical birth, is certainly one of the most prevalent identities, and the most at odds with the reality of who we are. It remains one of the most destructive identities we can assume. As long as we tolerate the divisive pretensions of religious beliefs and identities, especially those of the three great Abrahamic faiths, we will all remain in the line of fire.
