The only reason apes exist is because lets say we in fact evolved from them the difference is that certain apes decided to go on the ground and walk on the ground while other stayed in the trees. The ones in the trees stayed apes the ones on the ground turned into humans.
I disagree that you include facial features because people withink these groups as you define them can have a range of facial features. If there wasn’t than all people would look exactly the same if there weren’t variants. If you are saying that facial feature define race then all the people with high-cheekbones would be one race, all the people with point noses would be another race and so on.
As for racial identity i hope in the future it stops existing I for one am all fore globalization and the creation of one “race” as you call it. My race is not who I am, my country is not who I am nor my culture, “I” am not a static thing that can be defined by character attributes, physical attributes, cultural attributes etc. Because none of those are static they are always moving always changing things.
The only way races would exist as you mentioned was if every group that went out from the cradle of civilization lived in one area without contact for thousands upon hundred of thousands if not millions of years evolving on their own. But because we reproduce we grow and expand and eventualy meet the others and eventualy after that overflow into each others gene pools until there is but one race. So too bad so sad and unless you nuke every race except your own whats destined to happen will happen. And you probably would do so if you had the chance.
