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.
Piglet would like a word with you.
Also cats. Dogs. Lemurs. Rats.
Basically, any creature that has a pink nose probably has pink lips. We just don’t notice because they are mostly covered in fur and proportionately thinner than human lips.
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…
