The Causal Story of Creativity

There doesn't I haven't found any compelling evidence to suggest that you know one story should be privileged over another. There is both a causal story and empirical evidence to back up that causal story in the case of let's say creativity. In the melanin case we can measure the frequencies of these genes and they sure enough geographically they vary exactly in the way in which you would think that they would vary. We have very good reasons both are priori and actually experimental to think about what the selective pressure is.
