Aboriginal people are genetically most similar to the indigenous populations of Papua New Guinea, and more distantly related to groups from East Indonesia.
With this first large-scale study of genomes of Aboriginal Australians the researchers found, in contrast to many earlier theories, that this population derived the vast majority of its genetic ancestry from the same wave of migrants as all other present-day non-African populations, who left Africa approximately 60- ...
By comparing Aboriginal genomes to other groups, they conclude that Aborigines diverged from Eurasians between 50,000 and 70,000 years ago, after the whole group had already split from Africans.
Our results show very clearly that Aboriginal Australian people living today are the descendants of the First People to enter Australia, who lived between 25,000 to 40,000 years ago. There is substantial evidence of admixture or intermixing with Asian, Oceanic and European people within the last 200 years.
So there was another family that didn't get about much. Getting back to the Australian aborigines, separate research has shown that they have roughly the same Neanderthal DNA component as non-Africans, which indicates they split off after at least the first interbreeding between the two species.
Results: The Aboriginal and non-Aboriginal populations had significantly different ABO and RhD distributions (P < 0.001). For Aboriginal individuals, 955/1686 (56.6%) were group O and 669/1686 (39.7%) were group A. In non-Aboriginal individuals, 1201/2657 (45.2%) were group O and 986/2657 (37.1%) were group A.
A new genomic study has revealed that Aboriginal Australians are the oldest known civilization on Earth, with ancestries stretching back roughly 75,000 years.
Aboriginal people are genetically most similar to the indigenous populations of Papua New Guinea, and more distantly related to groups from East Indonesia.
Aboriginal Australians could be the oldest population of humans living outside of Africa, where one theory says they migrated from in boats 70,000 years ago. Australia's first people—known as Aboriginal Australians—have lived on the continent for over 50,000 years.
It is true that there has been, historically, a small number of claims that there were people in Australia before Australian Aborigines, but these claims have all been refuted and are no longer widely debated. The overwhelming weight of evidence supports the idea that Aboriginal people were the first Australians.
Their dark skin reflects an African origin and a migration and residence in latitudes near the equator, unlike Europeans and Asians whose ancestors gained the paler skin necessary for living in northern latitudes.
Indeed, by 31,000 years ago, most Aboriginal communities were genetically isolated from each other. This divergence was most likely caused by environmental barriers; in particular the evolution of an almost impassable central desert as the Australian continent dried out.
Prehistory. It is generally held that Australian Aboriginal peoples originally came from Asia via insular Southeast Asia (now Malaysia, Singapore, Brunei, East Timor, Indonesia, and the Philippines) and have been in Australia for at least 45,000–50,000 years.
All living Aboriginal Australians descend from a single founding population that arrived about 50,000 years ago, the study shows. They swept around the continent, along the coasts, in a matter of centuries. And yet, for tens of thousands of years after, those populations remained isolated, rarely mixing.
Geneticists have calculated from mutations present in the Aboriginal Y chromosome that the first inhabitants of Australia had separated from other members of Homo sapiens living elsewhere in the world about 50,000 years ago – probably long before our species had arrived to live in Europe.
Some aboriginal Australians can trace as much as 11% of their genomes to migrants who reached the island around 4,000 years ago from India, a study suggests. Along with their genes, the migrants brought different tool-making techniques and the ancestors of the dingo, researchers say.
Indigenous people have lived in Australia more than 65,000 years ago, according to scientific evidence of human occupation1. To put this in perspective, this is ten times older than the ancient Egyptian pyramids.
Molecular clock estimates, genetic studies and archaeological data all suggest the initial colonisation of Sahul and Australia by modern humans occurred around 48,000–50,000 years ago. Over the last few decades, a significant number of archaeological sites dated at more than 30,000 years old have been discovered.
Some are near-white like the F1; but none darker than either parent have been seen. Study of the various crosses leads to the conclusion that a single main gene for melanin in the skin is present in the aborigines, together with a minor gene which alone produces brunet-white skin colour.
Paleogeneticists realized about 10 years ago that most Europeans and Asians inherited 1% to 2% of their genomes from Neanderthals. And Melanesians and Australian Aboriginals get another 3% to 6% of their DNA from Denisovans, Neanderthal cousins who ranged across Asia 50,000 to 200,000 years ago or so.
She compared the genomes of 344 individuals in Northern Territory, Papua New Guinea, South East Asia - and India. She estimates that the Indians contributed nearly 10% to the Australian Aboriginal genomes.
Are Maoris and Australian aboriginals related? The Maori of New Zealand (NZ) and the Aborigines of Australia are not related in modern contexts. The Aborigines came to Australia about 40,000 years ago from Africa while the Maori came to NZ about 1,000 years ago from Polynesia.
The closest individual and therefore the most similar to the "perfect genome" is an individual that corresponds to a Puerto Rican woman, and we can relate it to the Taino India known as Yuiza.
Yes, the first humans were almost certainly black. The human species evolved in East Africa about 200,000 years ago. Black skin was necessary for survival in this hot and sunny climate.
All modern humans share a common ancestor who lived around 200,000 years ago in Africa. Comparisons between known skin pigmentation genes in chimpanzees and modern Africans show that dark skin evolved along with the loss of body hair about 1.2 million years ago and that this common ancestor had dark skin.
