Do humans have a faith instinct?

[SamIam]

It seems as though history always describes a faith of some sort in ancient and not so ancient peoples. Anthropoligists often make the same observations of the peoples they study. So is faith somehow on one of our genes?

The biologist Edmund O. Wilson considers us an altruistic species. As Franklin said, we must all hang together or we shall all hang seperately. If early groups of hunter/gatherers stuck together to fight wolves or big cats or human enemies from another tribe, they stood a much better chance of survival. This was altruism in action. Religion helped codify these altrustic acts.

So, do we have a "religous" gene whether we chose to admit it or not?
