not found on most animals, if it is allowed to grow free it can be quite thick and long, gets in the mouth and nostrils.
What purpose did it serve when we had no tools to trim it?
In: Biology
I’d say probably as a result of a few women loving facial hair on men back when we were all cavemen and that… or at least, at some point during history.
I haven’t noticed any other species with a mustache and i also know that humans are the only species that have engorged breasts without the females needing to nurse sooo, i would assume it was probably to do with mating purposes and that someone just so happened to have the mutation and it passed its way down.
I’m assuming sexual as the function because kids don’t haves beards which rules it out as being a version of the hair on the scalp, considering that underarm hair and pubic hair also develops around the same time as facial hair.
