That's a damaging response, and that's why I want to emphasize so much the social and environmental factors are the real things that people should be worrying about, that said, as a geneticist, I think it is important to know the evolutionary history of the genetic variants we find that do have effects on traits. The effects of Neanderthal DNA traits are detectable, but they're modest.
