Evolution is usually described as “the survival of the fittest,” or as species evolving to adapt to the environment. To survive, to evolve, to adapt—these are action verbs, implying some kind of intention or general plan. But there is a curious inversion of logic, or reversal of causality in the theory of evolution. This is almost the opposite of intention or plan.
It is easiest to illustrate this inverted logic using examples. Suppose you are on a tropical island, enjoying the nice weather and the beautiful beach. You say to yourself, “This is perfect. This is paradise!” Naturalmente, there is some specific gene containing the blue print of your brain process that leads you to feel this way. It stands to reason that there may have been genetic mutations at some point, which made some people hate this kind of paradise. They may have preferred Alaska in winter. Evidently, such genes had a slightly lower chance of survival because Alaskan winters are not as healthy as tropical paradises. Over millions of years, these genes got all but wiped out.
What this means is that the tropical paradise does not have an intrinsic beauty. It is not even that you happen to find it beautiful. Beauty does not necessarily lie in the eyes of the beholder. It is more like the eyes exist because we are the kind of people who would find such hospitable environments beautiful.
Another example of the inversion of logic in evolution is the reason we find cute babies cute. Our genes survived, and we are here because we are the kind of people who would find healthy babies cute. This reversal of causality has implications in every facet of our existence, all the way up to our notion of free will.
