The Importance of Sexual Selection in Human Brains

I think that we should have a prior that there will be some sex differences. The argument that sexual selection that we observe in the animal kingdom and that we assume humans faced as well should shape our priors. How do people arguing that there are no innate differences in male and female brains deal with that fact? Do they claim, you know, yes it would be surprising a priori but the evidence just is strong enough that we should conclude that in the case of humans it didn't actually turn out that way or do they dispute the fact that sexual selection exists?"
