I wonder if there is any evolutionary advantage to larger breasts. AFAIK, there’s no difference in their ability to deliver milk to babies. And smaller breasts probably have an advantage in a woman’s movement and agility, not to mention avoiding back pain. Humans also seem to be the only animal that has larger breasts than necessary – OTOH, humans are also the only mammal that walks upright, so there are other biological differences.
If it’s the case that the only evolutionary reason for large breasts is to better attract (some) men, that would be interesting.

It’s not like large breasts are more common than not large (unless you mean anything larger than nothing at all). I suspect there was a random mutation, and it didn’t hurt their reproduction chances but it didn’t help either. So you end up with a variety of breast sizes.

Milk cows have larger breasts than necessary, but that’s from artificial breeding rather than any sort of evolution or adaptation.
