Did you know that the entire human species has less genetic diversity than a a single troop of chimpanzees? Humans had a massive genetic drift event in our past, possibly the Mt toba super volcano 65kya. We are talking 10-15,000 humans total on the whole planet.

Any differences humans have are genetic super small, and certainly don't justify any real special designation as sub-species. People will point to the thirty different crows that all look alike, but are separate species. they fail to acknowledge the technical definition of species being the ability to create viable offspring, and we all know race mixing is totally a thing.

Really though, the differences between humans is really not that much. Alot is just the whole needing more melonin on the equator for folic acid production thing, and that northern peoples need less for vitamin D. Burgmans and Allen rules about how lanky skinny critters do better in the heat than fatter stubbier critters in the cold takes up another big chunk.

Human faces are a big harder to categorize, but I know for sure humans have evolved very special attention to the differences between faces. Looking like your father would be a big advantage, basically helping your dad decide to stick around and help raise the kid. Blue eyes and red heads are thought to be a part of that.

> I got an A in Anthro 101, I think I know what I'm talking about. Also dogs are special, think about how much humans have messed with them over the years. Wolves look pretty similar to each other.
