According to a recent study, the oldest continuous human civilization up to the present era is currently in Australia. According to a recent DNA study performed by Australian scientists, the ancestry of indigenous Australians stretches back roughly 75,000 years. The study involved DNA sampling of 83 Aboriginal Australians and 25 Highland Papuans from Papua New Guinea. Research revealed that the ancestors of modern Aboriginal Australians departed from the African continent some 75,000 years ago, when climate conditions in Africa changed.

The ancestral origins of Aboriginals in Australia has long been debated. Some theories suggest indigenous tribes formed in waves, as nomad groups arrived to the continent.
