The sociobiology leading to the conclusion that women are ill suited to be part of the larger society, and should be subordinated to husbands and fathers, rests in large part on high reproductive variance among males in the ancestral environment, the environment of evolutionary adaption.
Now it obviously seems likely that reproductive variance among males was extreme – just look! And pretty much everyone in the manosphere agrees that it was, but until recently, I have not been able to find any good science pinning it down.
Throughout most of human history, almost all women reproduced but only one male in three reproduced. During the neolithic, from agriculture to the start of the bronze age (very rough dates) one male in seventeen reproduced – sixteen males died without children, one male had seventeen wives, concubines, and slave girls. After this roughly four thousand year period of very extreme inequality, it returned to its long term norm, one male in three – all races, all cultures, all societies, and it is been at roughly its long term norm for the past four thousand years or so.
