I think it's just a kind of quantitative freak out. For instance, you have something, anything at all, that's just an ordinary normal size, then, one day, you see another of them that's either huge or very small and you can't really help but look at it in wonder. "WOW!! Look at the tires on THAT truck!!" Well, it's the same with tits.
Also, anthropologically speaking, we used to walk around on all 4's like simians still do, so, the one thing that attracted a male to female was her ass. Once we learned to walk erect, her ass was no longer in our face, so, breasts grew to take the place of the ass. They DO look similar! So, the girls ARE there for purposes of sexual attraction! Nature is just doing it's part to help keep the species alive and all women can do is complain about guys looking at what naturally is very attractive to them.

First, I think you meant biologically...not anthropologically...Actually, there are tons of cultures that don't have the same breast fixation that Americans and some Europeans do. There are a few theories floating around as to why that is but they haven't settled for one yet. Some feel its the dichotomy between simultaneously hiding them away like a prized possession (daily lives) and presenting them on a platter (the media). Cultures where breasts are exposed in daily life don't have the same view of breasts. Funny because, anthropologically speaking, they live closer to the way our genetic ancestors did than we in the "civilized" world.

I can assure you though, breasts grew to feed young...not to attract males ha haha. Its that mind set that prevents women from being able to breast feed in public (what they are supposed to be used for). Biologically speaking, breast obsession makes no sense because essentially breasts are baby food and not actually a sexual object.

I'd think the biggest reason cultures that walk around topless aren't obsessed with breasts is BECAUSE they are a topless culture! If we'd do the same thing, eventually seeing naked breasts would be no big deal either.
Our ancestors, primates, don't have breasts at all UNTIL they have babies!! So, obviously, there's NO reason to have then constantly except for sexual attraction. Flat-chested woman and men can breast feed, too, but you don't see them walking around with a chestful, so, very obviously, protruding breasts are NOT needed just to breast feed. They HELP, but they're not needed.
