> Let's bring human female breast size into the discussion as well, another unique feature among mammals (not counting cows..?)

I read a comment on HN once, someone linked to some random blog, maybe a biologist or anthropologist that had an amazing theory for why breasts developed the way they did, discounting the aquatic ape theory and others.

I've never been able to find it with only the obvious keywords, maybe someone will repost it in this thread.

Of course, I also don't remember what the theory was at all, which also makes it hard.
