Reproductive skew

Reproductive skew is the difference in reproductive success between members of the same gender. A 'high male reproductive skew' for a species would mean there is a high variance in reproductive success among men. There is substantial evidence that in humans (and many other animals), the females have a lower reproductive skew. Bateman's principle suggests this pattern is caused by sex differences in parental investment.
