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.
Yeah if we’re saying it’s weird meaning it’s unusual, then no it’s not weird. And if we’re saying it’s weird meaning bodies are weird in general, then yeah, it’s weird that we have colored lips, and also weird that we have bone-like protrusions sticking out into our mouth, and weird that we have little hairs growing right out of the surface layer of our skin.
As soon as you think closely about any piece of it, all the pieces start to seem bizarrely weird.
