The oldest homo sapien fossil is about 300,000 years old. 3 million years ago would still be in the latter half of the reign of the Australopithecus genus. Homo habilis hadn't even appeared yet to kick off our genus.
That makes sense. I was confused because I just read a paragraph that talked about archaic humans of 2 million years ago. But now I realise it was using the term in a more general sense - specific to Homo rather than Homo Sapien
