Why Woman Have Breasts?

Seriously, from evolutionary point of view, why does breasts exist? Have you ever give a thought on that before? It has no biological advantage, just like nipples on males, it doesn't make sense. It takes nutrient to maintain, and I'd say alot of nutrient, many girls usually lose a cup size after a successful diet (what a waste). Furthermore, it is not 'aerodymanic', try imaging running around with two lump of lard front of your chest, and at a time when there's no such thing as bra, like stone age, having a breast is hindrance, something that ensure you get chased down by sabretooth tiger in no time. So why?

From creationist point of view, why did God designed woman that way? If what He wants is abstinence for everyone, why not just design the breast to develop after a woman had her first sex or first pregnancy (like most animal do)? instead of develops when one reached puberty. Maybe he wants everyone to have sex when everyone at puberty afterall, in His great design plan. Now you see the absurdity? I meant the idea of creationist, not abstinence (chill, Justin). It's obviously bullshit, which many will easily agree, so creationist view is not going to be in our discussion. And by the way, I think abstinence is also proposed by the same group of people who proposed the creationist view, and don't forget geocentricity, saying the earth is center of universe, some people still believe that. It was on the newspaper few weeks ago, which the guy said, it's proven in bible. I think the bible also proved that stupidity is infinite through that guy. What a great book.

There must be a reason for this, and don't you just glad we have institutions like university with smart peoples on trying to solve every type of problems and answer all kind of questions out there. And here is the explaination of our breast problem through evolutionary psychology point of view, it's a great essay. It tried to explain why breast evolved (something to do with "Fisherian run-away selection", same reason why peacock have such frivolous feathers), and why men find breast is sexy (which how the breast looks could have some hidden signal, for example, larger breasted female may be a signal that one has enough fat, and may bear fatter child, an advantage for insulation, and body food storage). There is also some interesting stuff in it that I didn't know about before, like chimpanzees which we share common ancestral don't have permanent breast, it develops on a as needed basis. It's a 'turn off' for males chimpanzees to see a breast, unlike human, because a developed breast on female chimpanzee means it's about to give birth, or had just gave birth, trying to copulate will just be a waste of precious sperm, since it is very difficult to get pregnant in time like that.

There is so much more in it that I can't bother to list them out one by one. Go read it yourself. It's a damn good piece of work.
