Comment on Why do Orks from Warhammer 40K have nipples?
Strider@thelemmy.club 2 months agoThat’s the thing with natural selection though, as long as a trait isn’t deleterious and it’s common enough it’ll generally stick around. There’s no pressure for males to not have nipples.

Totally agree with your point. But it’s also not something that will actively promote fitness.

Doesn’t matter. There’s no reason to not have nipples, and going down the evolution rabbit hole to change that isn’t worth the random mutations that are more likely to just straight up kill males during development or something. Your entire body is built on the concept of, “good enough to get the job done.” In biology fitness just means the ability to successfully reproduce, not actually who’s stronger or more efficient.

Agreed. All about the ability to reproduce, not actual strength or “fitness” as most people would think of.
But yeah, they’re more or less vestigial as far as I’m concerned. Good point on it not worth getting rid of because that would probably be more detrimental (as you stated).
