I have a pet theory for this phenomenon. If you look at recently contacted peoples or those who have little contact with the outside world, endemic warfare is common. In these societies, well over 20% of men are killed in the ongoing conflicts. Evidence points to endemic warfare being common for most of human history and prehistory. Looking at our closest evolutionary cousins, the chimpanzees, it is the same if not more brutal. I think, on average, that men are more polyamorous than women partially because this fit our environment. It allowed women in a clan to be in child-bearing partnerships even if gender ratios were grossly imbalanced. While we are now in a very different environment where almost all men survive, our relative sexual and coupling urges have remained the same. Through most of the modern-era, post feudalism, this was solved through socially enforced monogamy. Now of course, with loosening restrictions, polyamory is gaining an acceptance it probably hasn't experienced since earlier eras of endemic warfare. To be clear, the lack of violence in modern life is a strictly _good_ thing. But I'm not sure where it leaves us for the future.
