The results suggest that genetic variation of Aboriginal Australian follows very marked geographical patterns, a feature that had already been detected in other regions of the world (e.g. in Europe) but due to the peculiar history of the Australian continent and its implications for understanding the origin of humans ...
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.
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.
It's possible, depending on how distant the Indigenous Australian ancestor is, that you share too little DNA with them for our DNA test to detect it. A DNA test is not any kind of prescription of identity; rather, a person's genetic makeup is only one part of their story.
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.
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.
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. The newly published paper is the first extensive DNA study of Aboriginal Australians, according to the University of Cambridge.
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.
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.
Not even AncestryDNA, which has amassed more than 10 million samples, has enough to offer a “direct estimate of Aboriginal Australian ethnicity”. This means Aboriginal ancestors can only be reliably detected through direct maternal or paternal lines (using mitochondrial and Y-chromosome tests).
A new genomic study has revealed that Aboriginal Australians are the oldest known civilization on Earth, with ancestries stretching back roughly 75,000 years.
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.
The Australian Government defines Indigenous Australians as people who: are of Aboriginal or Torres Strait Islander descent; identify as being of Aboriginal or Torres Strait Islander origin; and are accepted as such in the communities in which they live or have lived.
The DNA sequences showed that the ancestors of Aboriginal Australians and Papuans had then split from Europeans and Asians by at least 51,000 years ago. By comparison, the ancestors of Europeans and Asians only became genetically distinct from each other roughly 10,000 years later.
In Aboriginal individuals we found that group O was more common than A in the 'Northern' NT, whereas there was similar distribution of the groups in 'Central Australia'. Conclusions: We found a significant difference in ABO and RhD blood groups between Aboriginal and non-Aboriginal individuals in the NT (P < 0.001).
Aboriginal Australians became genetically isolated 58,000 years ago, tens of thousands of years before other ancestral groups, making them the world's oldest civilization.
Australia is home to the oldest continuing living culture in the entire world. The richness and diversity of Aboriginal and Torres Strait Islander cultures in Australia is something we should all take pride in as a nation.
Aboriginal peoples
Genetic studies appear to support an arrival date of 50–70,000 years ago. The earliest anatomically modern human remains found in Australia (and outside of Africa) are those of Mungo Man; they have been dated at 42,000 years old.
Rarest Eye Colour – Green.
Some Melanesians and Aboriginal Australians have naturally blonde hair without admixture with whites.
Europe has the widest variety of eye color, according to Custers, who adds those of European descent are the largest population of blue eyes. Europe was the epicenter of the blue-eye gene mutation.
Some tribes require as much as 25% Native heritage, and most require at least 1/16th Native heritage, which is one great-great grandparent. If you don't know who in your family was a tribal member it's unlikely that you would be able to meet the blood quantum requirement.
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.
By 31,000 years ago, most Aboriginal communities were genetically isolated from each other, giving rise to great genetic diversity.
