Have any other human species been found in America?
Do we know if they had a propensity to eat kale and avocado :P ?
If Homo erectus made it to east Asia(‡), and given that as far as we know it was possible to walk from Asia to America back then, it's not difficult to imagine that some of then did make it to the Americas, but raises the question of why they didn't survive.
