ABSTRACT
For Osborn the Nordics were superior for the same reason any superior animal group was: they possessed a superior race plasm, followed the natural laws of evolution, and had enhanced their greatness by struggling to go further. In addition, the Aryans were a more generalized form, closer to the original point of human radiation. This allowed them to adapt more easily to changing conditions and overcome them. Non-Aryans had become biologically specialized to fit their particular niches, and thus were less able to advance. Africans, Asians, Australian Aborigines and other people of color occupied the far-flung edges of the world while Europeans were centrally located. As he believed it did for the other mammals, Osborn believed this geographic distribution, and level of biological specialization, showed Central Asia to be the home of the human race.
