Often evolutionary 'facts' are interpreted through bias. It can be cultural bias, or gender bias, or other.
Feminists argue that as men’s ideas about gender have changed, so have their interpretations of evolutionary evidences.
Darwin postulated that females are ''coy,'' mating rarely and choosing their mates carefully, presumably betting their odds on the males with the best genes to contribute to their offspring. For their part, males are ''ardent'' and promiscuous, and fight amongst themselves for female partners. Later theories added that males are promiscuous because they have less to lose by making babies - unlike eggs, sperm are plentiful and small. Plus, females usually do most of the work to raise the offspring”

“In the mid-nineteenth century, social Darwinists invoked evolutionary biology to argue that a woman was a man whose evolution - both physical and mental - had been arrested in a primitive stage. In this same period, doctors used their authority as scientists to discourage women's attempts to gain access to higher education. Women's intellectual development, it was argued, would proceed only at great cost to reproductive development. As the brain developed, so the logic went, the ovaries shrivel. In the twentieth century, scientists have given modern dress to these prejudices. Arguments for women's different (and inferior) nature have been based on hormonal research, brain lateralization, and sociobiology.?
