Of course, this goes both ways. Women have also become much more attractive over the eons. Just who do you think were the 'old maids'? Hot chicks were picked off at 16+. (I think the marriage age is 14 in Miss with parental consent.)
You can still see this today. How many heinous women are lezzies? How many times have you seen a ugly chick and thought that's she's too unattractive to breed?
