Part of the reason I dislike many evo-psych explanations as an archaeologist is that they end up reflecting a lot of the author's assumptions about the nature of human societies and not the diversity of forms we actually observe. You can support virtually any argument by just narrowing or widening this scope appropriately. One example here is that young women are free to actually decide which "suitors" to accept. In some gerontocracies, young women generally don't have that choice, socially at least.
