Where's the fight? Is it so un-obvious to folk? Females do not have full hair development because less-hairy females were selected as they resemble younger women, i.e., those with a longer potential future mating period.
I would not be surprised to discover this selection factor reaching all the way back past
H. erectus. The attractiveness of a female with a longer future mating potential is so overwhelmingly greater than one with a shorter future mating potentialespecially in pre-civilized society/groups with high infant mortality and horribly lengthy gestation periods. Therefore, any females who can even
resemble the younger ones, i.e., pass themselves off as one, will receive more mating attention.
Can the matter be put to rest now? Good lord!
