Everyone can agree there was multiple human species in prehistoric times. The current zeitgeist is "one race, the human race", suggesting that we're all one species.
If you ask a "one race"r when the different human species became one single species, you crash their operating system.
There's actually two human species whose gene pools were totally separated from the bulk of humanity, for tens of thousands of years. I'll give you a hint: one of them is the original Australians.
Sub-human?
