          By DNA analysis that was completely on the table till they went extinct.

            No “till”, plenty of living beings have vestigial elements that were positive at some point of their history, yet no longer are, but are still maintained because there isn’t evolutionary pressure to get rid of them.

              “They” was towards neanderthals not vestigial elements. They are extinct.

                Homo Sapiens develop a mutation XYZ that makes them not be attracted towards Neanderthals -> Neanderthals go extinct -> XYZ is NOW vestigial.

                  The genes were from Neanderthals not to make them unattractive and they’re also not vestigial. One is a very common gene related to blood clotting and can cause a higher risk of heart disease.

                  In other words, humans were fucking Neanderthals and we know it because of DNA. If they had never gone extinct it is without question the boinking would have continued.

      Same as boobs, Human female breasts are mainly sexual, they are too large for babies to feed.

        I’m sorry, but this isn’t correct, adult human females have breasts to hide when they are in estrus, by always being swollen, it’s called hidden estrose, it’s a whole thing. This has a lot of data backing it up. I KNOW I’M SPELLING IT WRONG! PROOFREADING IS THE LAST RETREAT OF COWARDS!!!

        they are too large for babies to feed.

        Then it seems I must have seen some of them fake it really convincingly for some reason.
