John Hawks looks at a recent study of recent genetic mutations in humans linked to their surmised functions.
In theory, if human evolution make some key breakthroughs at times associated archaeologically with inferred timing of the appearance of new genes dealing with relevant functions to those developments, we could tell a story of genetic mutations leading to the dramatic success of our species. But, due to methodological issues and the weakness of the evidence, he comes down solidly in the agnostic camp at this point about this kind of narrative.
