>A comprehensive survey of traditional societies in the world shows that 83.39% of them practice polygyny, 16.14% practice monogamy, and .47% practice polyandry. Almost all of the few polyandrous societies practice what anthropologists call fraternal polyandry, where a group of brothers shares a wife. Nonfraternal polyandry, where a group of unrelated men shares a wife, is virtually nonexistent in human society. Why is nonfraternal polyandry so rare? [0] While human nature can change, something as fundamental as human sexual family unit preferences radically change from favoring polygny over an order of magnitude more than polyandry seems unlikely to be overthrown simply because of changes in democratic opinion on legitimacy of polyamory. Using history as an imperfect precedent, one could make an educated assumption the balance will tip towards leaving lots of unmarried men on the sidelines rather than unmarried women. Evolutionary constraints may also push against having women on the sidelines, since the sexual reproduction throughput is rate-limited by females. There is little evidence to suggest polyandry is as common as polygny. [0] https://www.psychologytoday.com/us/blog/the-scientific-funda... |
