TIL humans are the only animal with a chin. We aren't sure why.
TIL humans are the only animal with a chin. We aren't sure why.
It's an evolutionary conundrum, and scientists are still divided over the answer
You're viewing a single thread.
Would you mate with somebody who didn't have a chin? Chins are sexy.
Why are chins sexy?
Because they make people want to mate with you
Why do they make people want to mate with me?
Because they’re sexy. We’ve been over this.
Because otherwise you might be mating with a Neanderthal.

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.

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

Same as boobs, Human female breasts are mainly sexual, they are too large for babies to feed.
I refuse to believe that someone is dumb enough to actually believe this.
What? No other mammal has breasts like human females, and they are full of touch senses unlike other. They are clearly part of human sexuality.
did you have a stroke and forget the second part of your comment?
I'm pretty sure they did.
Elephants do for a start.
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.
I'm Asian and this is not true for my breasts, tyvm
