Indigenous Australians are Earth's oldest civilization: DNA study

Genomic data was collected on 83 Aboriginal Australians and 25 Highland Papuans The study reveals just how ancient Indigenous Australian civilizations are (CNN)A new genomic study has revealed that Aboriginal Australians are the oldest known civilization on Earth, with ancestries stretching back roughly 75,000 years. In a study published in the journal Nature Wednesday, a group of international researchers -- including nine Aboriginal leaders -- collected genomic data on 83 Aboriginal Australians and 25 Highland Papuans from Papua New Guinea. The findings indicated their ancestors had diverged from Eurasians 57,000 years ago, following a single exodus from Africa around 75,000 years ago. The data may show Aboriginal Australians came to the continent as early as 31,000 years ago.
