text: what evolutionary reason is there that women lack facial hair? what benifit is it that women do not grow beards, but men do? i think the scientific jury is still out on that one, but in my unscientific opinion, the answer is obvious: as the human male brain developed and evolved, so did its sense of beauty which began to include women, and women without facial hair just began to look more beautiful to men than those with it.  it was and is just one more way to differentiate women from men so to allow the 2 sexes to be attracted to each other.  that's why homosexuality is so unnatural.  think about it, if men and women looked almost the same, what would attract us to each other?  it is our differences that attract the 2 sexes, not similarities.
