You're wrong, neutral genes do affect those traits. There's not any evidence that intelligence or strength are under directional selection that would make populations diverge

You need to show a specific kind of selection, one where human populations have different selective pressures. No evidence of this exists (and some evidence exists showing it is not the case). If selection has acted on humans it's acted on us all in the same way

Australian Aborigines have excellent visual memory and their visual cortex is 25% larger than Europeans. It would be interesting to know why that is.

Not really, but also no reason to jump so quickly to a genetic explanation

I don't know. But there's no reason to think that genetics is the only possible answer.

They have lower cranial capacities, too. Also genetic of course.

"of course" is a favorite phrase of yours, I'm guessing.

I'm curious what possible *non* genetic cause could result in smaller cranial capacities. "Hearing mean things makes your skull grow smaller" is the alternative and is insane.
