> men tend to have more variance in everything due to having only one X chromosome The variability hypthesis is interesting (and old), but I don't follow what you said about X chromosomes and males, or how it pertains to the variability hypothesis. I'm pretty much ignorant in genetics. Does your assertion follow from this observation: "if X chromosome has a genetic disease gene, it always causes illness in male patients, since men have only one X chromosome and therefore only one copy of each gene"? As in, men exhibit more variability because their genetics are less stable, because they don't have a Barr body? https://en.wikipedia.org/wiki/X_chromosome https://en.wikipedia.org/wiki/X_chromosome > As every function of the society scales more and more, more things become winner-takes-all games and end up being male dominated. That kind of needs some explaining too.
