The aboriginal Australian I would say is not the same species. When I saw a couple of them in person they didn’t look at all human. Many African people are definitely the same species but I would certainly say some are not…biologically it’s a bit of a debate as one class of biologist classify things that can successfully reproduce as the same species (lions and tigers can reporduce) most biologist classify species as separate if they do not reproduce with each other, and more modern,y they make genetic distinctions.
NIST too.
