The ‘out of Africa’ concept, which classified the first ancestral group as people originating from sub-Saharan Africa, still holds firm. The second group stretched from North Africa across Europe and east to the border with China. The third encompassed the eastern regions of the Asiatic land mass and, across the North Pacific Ocean, the North and South Americas and Greenland. The fourth, more geographically isolated, region consisted of the South Pacific Islands, Australia and New Zealand. This resulted in the four archaic classifications of Negroid, Caucasoid, Mongoloid and Australoid.
