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

Nonetheless, the result points to substantial sex differences in variance of reproductive success. Earlier DNA studies by Wilder and colleges (2004) estimated the historical sex ratio of reproductive success to be 2:1. Half the branches on a tree of ancestors represent males, but half of the males are repeats. Possibly 80% of women, but only 40% of men (i.e. half as many) have reproduced. | Nonetheless, the result points to substantial sex differences in variance of reproductive success.

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]]. | 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]]. | ||
