The actual findings dont support what you said. The difference in variance is not that large, it was found only in some small areas. Both person who brought it up severely overstate it basically.

Had the difference been caused by variance, you would find slightly more men at some places. You would not find "only men" nor "almost all men" as your comment claims.

And also, the world was build by plenty of completely sane people of both genders. Majority of it, actually.
