What is the Darwinian survival value of religion? That's not the right question, says Richard Dawkins. To find the right question, he relies on an evolutionary analogy: Why do moths fly into flames? It means instant death, so what's the evolutionary value of this kamikaze behavior? Dawkins delivers a crash course in proximate and ultimate causality, two very important distinctions in biology. Moths evolved to navigate using celestial objects as compasses. The moon and the stars emit parallel light, a very reliable and consistent beam, meaning a moth can fly in a straight line guided by that light. Candle light is an entirely different source that emits light in a spiral... leading straight to the hottest part of the flame. These moths aren't suicidal, says Dawkins, it's a misfiring of an evolutionary trait because of a modern technology in their environment. "The right question is not, 'What’s the survival value of a suicidal behavior in moths?'" he says, "The right question is, 'What is the survival value of having the kind of physiology which, under some circumstances, leads you to fly into a flames?'" There survival value of religious behavior may be at the genetic level, Dawkins suggests, and the proximate question in this case would be: what part of our brain does religion serve, and is religion really the only way that function is manifested?
