→Before 'enforced monogamy', women's effective population size was up to 17x larger than men's

* Societies that practice monogamy tend to show roughly equal ratios of male to female reproductive success, while societies that favor serial monogamy or polygyny tend to cause more variation in male reproductive success, while not affecting female success in the same way. | * Societies that practice monogamy tend to show roughly equal ratios of male to female reproductive success, while societies that favor serial monogamy or polygyny tend to cause more variation in male reproductive success, while not affecting female success in the same way. | ||
Note: This study was misquoted by Pacific Standard (psmag.com) to imply that ''17 women reproduced for every one man''. In truth, only the ''effective population size'' of women was 17 times as large as men's. The effective population size does not clearly distinguish parents and their offspring due to the similarity of their genes. A man with 20 children, each of which has 10 children in turn, would not contribute with 1 + 20 × 10 individuals to the effective population size, but considerably less than that. Anyhow, the result still points to substantial sex differences in variance of reproductive success. Reputed social psychology professor Roy Baumeister, estimated the sex ratio of historical reproductive success to be 2:1. Half the branches on a tree of ancestors represent males, but half of the males are repeats. | Note: This study was misquoted by Pacific Standard (psmag.com) to imply that ''17 women reproduced for every one man''.

The observation that males (humans and in the animal kingdom in general) exhibit a greater variance in reproductive success as compared to females is known as [[Bateman's Principle]]. | ||
