they aren't the same species of human as europeans and have more archaic/primitive traits, but they are still "human". again, genus homo is human. even homo erectus is human. sub-saharan africans are "human" in the same way. this line of argument will give much more success than calling them sub or non humans, and is also correct by definition. but you are right that they share many primitive traits that most eurasians lack.
