What are you even talking about? The many, many, many social scientists, paleontologists, art historians, archeologists, primatologists, child developmentalists, anthropologists that I have cited are not feminists. And yes, they answer why quite clearly. I've already talked to you about this, so I'm not going into it again. Besides, you clearly don't have any actual interest in any of that or you would have remembered it. Contrary to popular belief, patriarchy has only a small amount to do with gender. It's mostly about all sorts of other social stratification.

I've already answered your question about 4 or 5 times. In most of sexual reproduction, there is a male and a female and it takes both to reproduce. Even in animals, roles and behaviors are highly flexible depending on circumstances.

First of all, contrary to the view that the brains of men and women are strikingly different, none of these differences were particularly substantial. Even for the very largest, the overlap between the sexes meant that about one in five women were more “male-like” than the average male. What’s more, each data set had a different Top Ten list. As the authors point out, this shows that sex differences in the brain aren’t simply due to sex, but depend on additional factors, the most obvious candidates being age, environment, and genetic variation.

Edit: But also, within some species — including our own, as this chapter fleshes out some more — neither sex has the monopoly on characteristics like competitiveness, promiscuity, choosiness, and parental care. The particular pattern, as we saw, depends success. Not so, though, for behavior. None of which is to say that sex doesn’t influence us above the collar. But should we expect the genetic and hormonal components of sex to have the same kind of effect on the brain and behavior as they do on the reproductive system? With even that developmental process described by one expert as “a balance” rather than a binary system, we might start to wonder not just whether, but why, sex should produce male and female brains, and male and female natures.
