Pretty sure we are the only animals with pink rings around our mouth. It’s flipping weird.
It probably helps with verbal language understanding as humans often use mouth movements to interpret words (see McGurk effect). But I still think it’s weird.
Big pink rings.
They don’t really have lips like humans do. We have plump rings around our mouths. Those other animals do not
Tell that to the rest of the great apes…
Color may not be pink, but as 1 African language calls Whites “peeled man” people, lack-of-black isn’t defining of human, it is defining of the subset-of-humans who are caucasian, or who otherwise weren’t tropical-enough to need all the extra melanin ( thank you Bill Nye, for explaining that clearly ).
They’ve definitely got expressive lips, the rest of the great apes…

So other primates in the ape family. The same one humans are from.
I agree some apes have them but not other non-primate animals.
It’s likely we evolved ours for speech and emotion communication.
I still think it’s weird that we have them. A big pink noodle ring around the mouth.
