I think it's weird that we have pink rings around our mouth holes and I think it's weird we never talk about how weird that is.

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.

Mandrills, geladas, Rhesus macaques for a few.

Look at most Carnivorans (dogs, cats, etc) and they tend to have black lips. Is that less weird or more weird?

The human mouth is also the most sensitive area of the body (even moreso than lower areas), so that’s almost certainly related. More blood flow and a specialised cell-type…

They don’t really have plump ring lips like us.

Ah so they do. How bout that. Yeah I would agree those are pretty close to human lips.
