Because of the hegemony of fundamentalist religion in the United States, this country has been among the most resistant to the fact of human evolutio… - Jerry Coyne

Anybody who claims that people don’t cherry-pick their morality from the Bible, choosing that which comports with their extra-Biblical notions of what’s good and bad, is simply blind.

I could go on, but the point is clear: religions make explicit claims about reality—about what exists and happens in the universe. These claims involve the existence of gods, the number of such gods (polytheism or monotheism), their character and behavior (usually loving and beneficent, but, in the case of Hindu and ancient Greek gods, sometimes mischievous or malevolent), how they interact with the world, whether or not there are souls or life after death, and, above all, how the deities wish us to behave—their moral code.
These are empirical claims, and although some may be hard to test, they must, like all claims about reality, be defended with a combination of evidence and reason. If we find no credible evidence, no good reasons to believe, then those claims should be disregarded, just as most of us ignore claims about ESP, astrology, and alien abduction. After all, beliefs important enough to affect you for eternity surely deserve the closest scrutiny.

We humans have many vestigial features proving that we evolved. The most famous is the appendix.
