Red Is Not a Proxy Signal for Female Genitalia in Humans

That's also the reason for boobs; because pelvises aren't on eye sight to display how well they could gibe [sic] birth. Evolution just put up something similarly shaped up higher.

I'd not heard that before.

It's solid science which was well worth it's cost.

That's debatable.

I'd not heard that before.

There's no proof, but it's one of the popular theories. There's no need for boobs to be as big as on humans, other than looks.
