The origin of human races is a much-debated point among scientists studying human evolution. Many scientists argued that different race evolved from Homo erectus independently and that each adapted to a different place-Orientals in Asia, Caucasians in Europe, Aborigines in Australia and so on. Recently Scientists studying mitochondrial DNA from living human all over the world have argued that their research shows that all human races originated from one Homo sapiens ancestor in Africa. So, there are greater variations in Asia than in Africa.
