During the last glacial maximum, 26, to 19, years ago, ice sheets covered much of northern Europe, northern Asia, and North America. The eyes human adaptations of asians an epicanthal fold and are black or dark brown. Over time, migrations within Africa and back and forth between Africa and other regions and subsequent relative isolation brought about adaptations resulting in the Black race. Languages can be classified in terms of characteristics such as phonology, morphology and syntax into language families. The study of particular bone configurations can only be done by examining skeletons post mortem.

Southeast Asia: Human Evolution, Dispersals and Adaptations
They have black to dark brown skin, broad short noses, wooly black hair, and dark irises. The absence of the epicanthal fold in American Indian populations suggests this characteristic evolved after the Bering connection to America was severed about 10, years ago. The eyes are dark brown or black. Some populations were isolated sufficiently long in their new habitats to develop inheritable characteristics that distinguished their members from those of different provenance.
Elsewhere during that period there were numerous mountain glaciers. Polynesia includes Samoa, Tonga, the Marquesas, the Solomons, French Polynesia, and other island groups located within the Polynesian triangle. Dark-skinned indigenous peoples of India were for the most part isolated since about 6, B.
