I don't know I'd there's such a thing as a pure race necessarily, but I think the thing with noses is that most likely (and scientists believe this) the earlier hominids have flat noses, and all monkeys have flat noses, they don't have a nose bridge, so all our ancestors didn't have much of a nose bridge until a certain point, something caused them to develop protruding noses, thus I think you could be almost considered close to a "pure race" by not having a big nose, but see this was complicated by the fact that Neanderthals bred with us, so that's one reason for bigger noses, which is nit necessarily a bad thing I think but regardless.

So like my nose doesn't protrude a lot at the front of my face it isn't really that big, and also have a flat forehead that's not really curved at all

So thus I am not actually an inferior subrace or something in actuality
