Explanation for the origins of the Aborigines in Australia The origins of the Australian Aborigines has never been a mystery to Africans.. As far as Africans are concerned, the Australian Aborigines, Trobian Islanders and Melasesians are all part of the protohistoric African Diaspora.
The earliest Aborigine migration must have come from an ancestral homeland somewhere in northeast Africa, meaning they are direct descendants of the first modern humans to leave that continent, without any genetic mixture from other races.NA from the hair reveals that these ancient ancestors arrived in Australia around 50,000 years ago, and they somehow managed to keep the whole continent to themselves until the British convicts arrived many years later.
