Australopithecine bones are very different from those of modern humans in some key ways, they're not just "different-looking humans." But I'll let RAZD fill in the details there, he can tell you what we've learned about Lucy.



The human race is one species, homo sapiens. You seem to be asking whether any of us are racists or eugenecists. These prejudices don't have anything to do with the science of evolution.
