Genetic studies have revealed that Aboriginal Australians largely descended from an Eastern Eurasian population wave, and are most closely related to other Oceanians, such as Melanesians.
Some 90% of present-day Australian Aboriginals belong to the Pama-Nyungan linguistic family. This family originated only around 6,000 years ago, but according to the new study the people who speak the Pama-Nyungan languages today started to become genetically differentiated in Australia as early as 31,000 years ago.
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.
They conclude that, like most other living Eurasians, Aborigines descend from a single group of modern humans who swept out of Africa 50,000 to 60,000 years ago and then spread in different directions.
Genetically, while Aboriginal Australians are most closely related to Melanesian and Papuan people, there is also another component that could indicate South Asian admixture or more recent European influence.
These populations diverged from each other around 36,000 years ago, suggesting that they all descended from an early southward migration out of Africa. But Pugach also found evidence of more recent gene flow from India and northern Australia, which took place around 141 generations ago.
The original Australians were dark-skinned, but a large proportion of the country's Aborigines today are of mixed blood, and many appear to be white.
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.
A new genomic study has revealed that Aboriginal Australians are the oldest known civilization on Earth, with ancestries stretching back roughly 75,000 years.
The First Nations people of Australia consist of two culturally distinct Indigenous groups of black people, Aboriginal and Torres Strait Islanders, born inher- itors and custodians of the land.
The islands were settled by different seafaring Melanesian cultures such as the Torres Strait Islanders over 2500 years ago, and cultural interactions continued via this route with the Aboriginal people of northeast Australia.
The aboriginal skin, which is normally reddish mahogany or chocolate brown (not black, except perhaps in some northern tribes), is very subject to tanning (see Fig.
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.
Indigenous Australians are descendants of the original inhabitants of the Australian continent. Their ancestors are believed to have migrated from Africa to Asia around 70,000 years ago and arrived in Australia around 50,000 years ago.
“All indigenous haplogroups were found to be ancient, with estimated ages greater than 40 thousand years, and all were widespread throughout the continent.”
Willerslev and his colleagues found that individual Aboriginals from different parts of Australia could be as genetically distinct from one another as Europeans are from East Asians. This points to a long, long period of separation — tens of thousands of years living on opposite sides of massive deserts.
An unprecedented DNA study has found evidence of a single human migration out of Africa and confirmed that Aboriginal Australians are the world's oldest civilization.
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.
'Aborigine' is generally perceived as insensitive, because it has racist connotations from Australia's colonial past, and lumps people with diverse backgrounds into a single group.
However, Dr Misty Jenkins, who leads the Division of Immunology lab at the Walter and Eliza Hall Institute of Medical Research in Melbourne, said the ability to test DNA for Aboriginal genealogy does not exist.
Aboriginal people can be dark-skinned and broad-nosed, or blonde-haired and blue-eyed. Let's get rid of some myths!
People who identify themselves as 'Aboriginal' range from dark-skinned, broad-nosed to blonde-haired, blue-eyed people. Aboriginal people define Aboriginality not by skin colour but by relationships. Light-skinned Aboriginal people often face challenges on their Aboriginal identity because of stereotyping.
Yes. Plenty of tribal groups (their Mob) contain people of pure Aboriginal descent. The further North you go, generally, the purer the bloodline. It's fabulous that the oldest peoples in the world still exist happily on their original tribal lands.
The tribes in south India and Sri Lanka are genetically closer to one another than to the Aboriginals in southeast Asia and Oceania. Despite their morphological similarity there is no genetic evidence to suggest that the Indian tribes and Australian Aboriginals are biologically related.
