The aborigines of Australia........................are negroid types.............but have blue eyes.............like the Northern Europeans.......................why?.............Also, they tend to be short........like the pygmies of Africa............who are short b/c they live in the jungle.............being tall puts them at a disadvantage.............they would bump their heads in the Congo river basin.....................conversely, the so called bushman of the Serengeti (sp?) tend to be tall..................so they can reach up to trees..............there are not many trees in the Serengeti .........
