The findings have been published in the Journal of Human Genetics. Dr John Mitchell from La Trobe's Department of Biochemistry and Genetics, who led the study, said the research revealed there was a high level of genetic diversity among Aboriginal Australians.
Genetics. 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.
If you receive the Aboriginal and Torres Strait Islander region in your DNA results, this tells you that you probably had an ancestor who was an Indigenous Australian. If you are Indigenous Australian and do not receive this region in your DNA results, this should not subtract from your identity in any way.
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.
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.
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.
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!
Aboriginal or Torres Strait Islander heritage is voluntary and very personal. You don't need paperwork to identify as an Aboriginal person. However, you may be asked to provide confirmation when applying for Aboriginal-specific jobs, services or programs (for example grants).
A new genomic study has revealed that Aboriginal Australians are the oldest known civilization on Earth, with ancestries stretching back roughly 75,000 years.
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.
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.
One Nation NSW has proposed to abolish self-identification and introduce a “new system” relying on DNA ancestry testing with a result requiring a finding of at least 25 per cent "Indigenous" before First Nations identification is accepted.
The section offered the following definition: An Aboriginal or Torres Strait Islander is a person of Aboriginal or Torres Strait Islander descent who identifies as an Aboriginal or Torres Strait Islander and is accepted as such by the community in which he (she) lives.
In NSW Aboriginality determined through the Commonwealth Government definition can be confirmed through a Letter of Confirmation of Aboriginality or a Certificate of Aboriginality.
Wide nostrils of the aborigines again appear to depend on a small number of additive genes compared with the narrow nose of the white man. The lips of the aborigines tend to be thick throughout, but generally not everted.
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.
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.
It seems mapping your DNA is all the rage, from family history research to crime scene forensics. But for Australian Aboriginal people, or those searching their family tree, a DNA test will not necessarily give you confirmation of an indigenous Australian heritage.
The oldest known human remains found in Australia, Mungo Man, were found not to be related to modern day Aborigines in at least one study.
They also found a distinct genetic link between the Neanderthal blood types and those of an Aboriginal Australian and an indigenous Papuan, suggesting modern humans mated with Neanderthals before they migrated to Southeast Asia.
Stature was reconstructed by using humerus, femur, and tibia ratios to stature derived from Abbie's (1975) data on living Aborigines and the Trotter-Gleser method for blacks. The respective averages were 1,652 mm and 1,665 mm for males and 1,527 mm and 1,549 mm for females.
The oldest of the blood types, Type O traces as far back as the human race itself. With primal origins based in the survival and expansion of humans and their ascent to the top of the food chain, it's no wonder Blood Type O genetic traits include exceptional strength, a lean physique and a productive mind.
