CMV: Gender roles aren't socially constructed, they're a result of sexual selection.

I was listening to a podcast about Rojava when one of the female fighters started talking about what was basically feminist theory. She basically said that gender roles were socially constructed by men at the dawn of civilization to oppress women, which I dont really understand. It seems pretty obvious to me that its part of our nature, but maybe theres something Im missing?

In primates (and most mammals in general) males are the indiscriminate sex while females are the selective sex, because males produce sperm consistently at a low energetic cost whereas females produce a limited number of eggs only during certain times and at a higher energetic cost. This means it increases fitness most for men to have as many mates as possible since... they can.... while it benefits female fitness most to select the fittest possible mates in order to give their limited offspring the best chance of survival and reproduction. Males compete with one another for attention of selective females, and therefore more aggressive and dominant males are selected for. Men select for women who are more passive and emotionally sensitive because it makes them more effective at rearing children. Since men are more dominant and aggressive and women more sensitive it kind of follows that men would of course end up being the dominant sex. The sexual strategies themselves are also selected for which is why theres a pretty pervasive social more against women being promiscuous while men are generally lauded for having more sex.

The fact that they are socially constructed follows immediately from the observation that gender roles vary from time to time and from society to society. If they were part of our nature, then they wouldn't vary on such short time scales, and certainly not do so based on social constructs.
