But Neanderthal and Denisovan people are usually called humans, aren't they? As far as I know, all Homo are humans. Homo sapiens is just one of the human species, the only one that is still extant, usually called "modern humans". The only controversy I've heard on how to define humans is whether chimpanzees should be part of the Homo genus as well (making them humans, although a different species from us) or not.
