> people most likely lived in small tribes, so this idea that women have to be skeptical or critical of men doesn't really hold up. This premise and your thoughts on polygamy can coexist with my suggestion about women being selective. If you can have only a handful of pregnancies in your lifetime each of them carrying the very real risk of death for both yourself and the baby, as well as the burden of taking care of any children that survive, then you really need to make sure that your shots count and you're choosing the best mates from the tribe. Men don't have the same burden of pregnancy and childcare - additional partners only increase their chances of passing along their genes, so as a result they become far less selective.
