They actually are capable of producing a small amount of milk, it’s just that doing that requires so much effort for so little reward that feeding babies became the mother’s job after a few thousand generations of mammals being a thing.
Because males were females until the right amount of chemicals were introduced to the fetus. Take enough estrogen and males can produce milk and no longer have useless nipples.
Hmmm. Can’t say I’ve licked one personally, but I see what you’re seeing. I guess I meant an actual use for them. More of a rhetorical question I guess.
It is. I wasn’t being specific enough, sorry. Actual use in terms of evolutionary fitness. There are no reasons for them evolutionarily other than they are a byproduct of fetal development.
That’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.
What use are nipples on males?
sexual stimulation

Totally agree with your point. But it’s also not something that will actively promote fitness.
Anything that makes people hornier and more likely to procreate is an evolutionary advantage.
I suppose you’re right. It’s not just things that help things live longer or thrive in a specific environment.
