Evolutionary feminists would remove our inhibitions about examining animal behavior as a technique for thinking about human behavior. They would insist that people can think about the evolutionary pressures that elicit rape, for example, or other forms of violence, without necessitating any absurd pronouncement that because rape is "natural" it is in any way forgivable. After all, no one considers the case of the black widow spider, who kills and eats her male counterpart after mating, to mean that murder and cannibalism are okay. Any behaviors can still be studied as biological phenomena, regardless of how unpleasant they are.
Despite the admirable intentions of those who believe that patriarchy is solely a cultural invention, there is too much contrary evidence. Patriarchy is worldwide and history-wide, and its origins are detectable in the social lives of chimpanzees. It serves the reproductive purposes of the men who maintain the system. Patriarchy comes from biology in the sense that it emerges from men's temperaments, out of their evolutionarily derived efforts to control women and at the same time have solidarity with fellow men in competition against outsiders. But evolutionary forces have surely shaped women, too, in minds as in bodies, in ways that both defy and contribute to the patriarchal system. If all women followed Lysistrata's injunctions and refused their husbands, they could indeed effect change. But they don't. Patriarchy has its ultimate origins in male violence, but it doesn't come from man alone, and it has its sources in the evolutionary interests of both sexes.
