I've always wondered. Why are the genes for blue/green eyes or red/blonde hair recessive? Do you know the genetic explanation why we can't have blue eye genes to be dominant?

You should write about African hair sometime. Most Black women in the US spend a lot of money trying to make their hair straight. A lot of them just wear wigs or straight hair extensions (yes Michelle Obama also). I've personally observed Black women just hate staring at White and Asian women's straight hair.

Heat in Africa can't be the only explanation. Australian aborigines or South Asians live in hot areas and they don't have those tight curls.
