I'll ignore your feminist thing.
Please explain (I am actually interested in this):
1) Why is/was it good for women to have few partners and choose them wisely
2) Why is/was it good for men to have many partners
We can ignore the modern day if you want, but why was it so previously? And:
3) What has the rate of evolution (of humans, assuming they evolve, and of society and technology, assuming it evolves in the same sense that humans are supposed to) got to do with it? I mean by this - how would evolution affect this woman/man preference for sexual partners?
As women get pregnant, their ability to provide for themselves greatly decreases for 40 weeks. They also have harder time running from predators and doing other physical work. They cannot reproduce while they are pregnant. After that, they have a child to look after for a long, long time before the child grows enough to be self-sufficient to some extent. Because every time women have sex, they have a good chance of getting pregnant, and because every pregnancy is a huge commitment from the woman, they'd want to find the best possible partner. I.e, one with the best genetics, one who can provide and protect for them and their child. I'm not aware of how the early Homo Sapiens/Homo Erectus reacted to the children of other males of their desired/current female partner, but some species have been known to kill all offspring that isn't theirs when they find a new female for themselves.
For men, sex is a matter of minutes at most. After that, they can move on; the more females they can impregnate, the better. There was no alimony back when our genetics were written. The more impregnations, the better chances for males to get offspring that pass on their genes. The more offspring, the better chances that some of them are fully functional (no retardations or mutations.) There are many, many species where an alpha male has the monopoly on all the women; for the reasons mentioned before. Competition is bad news for everyone. The alpha, statistically, is the strongest and finest specimen around. When a stronger one appears, they become the alpha and voilá, the circle begins anew. So: For males, the more the better, no disadvantages.
Modern day technology largely invalidates all this. Abortions, condoms, society, alimony, day after pills..
tl;dr: what Balton said.
And Alex, I did not insult an opposing POV by my stab at feminism. As far as I know, Bane isn't a feminist.
