Macroskelic:
Macroskelic individuals have a sitting height between 53 and 55 percent of their overall height. Macroskelia is common in North and East Asia and a typical trait of many Mongoloids. Apart from that, it occurs in some Caucasus groups and a few Southern as well as Eastern Europeans. It is more common in parts of North America, especially in groups that came with the later migrations from Asia (Pacifids, Eskimids). Apart from that, it is not very common in native America, although in Fuegians a partial adaption to cold climate has taken place with shortening of the limbs. In the African forests, great relative trunk length is common in Pygmies. The short limbs of most Mongoloid groups are thought to have evolved during the Paleolithic when an ancestral population adapted to the cold climate of Central Asia (Allen's rule). It seems that Proto Mongoloid groups were still mesoskelic.
