But its not "on the whole evolved out". Thats like saying because redheads make up 1% of the population that they've "on the whole evolved out". And I guarantee more than 1% of women are hairier than most men. 

Being hairy isn't an uncommon trait. It is, however, seen as "undesirable" in most places if a woman is hairy. A lot of women will wax, shave, laser, or even bleach their body hair in order to appear less hairy.

Agreed. Women have quite a bit of hair, it's just not the coarse hair you typically find on men. Taking a close look at women who haven't napalmed themselves, you'll find fine facial hair on their upper lips, cheeks, and chins. Women have hair on their backs (especially the lower back), on their thighs, calves, and toes, and their nipples &amp; chests sometimes. Just as with men, it's going to vary individually, and by ethnicity. Blonds tend to be more hairy - more hairs per square inch of skin - than other hair colors but it's less noticeable because of the color.

More testosterone is going to make the hair more noticeable but, overall, humans are hairy creatures.
