Northern 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 new study suggests. Along with their genes, the migrants also have brought more advanced tool-making techniques and the ancestors of the dingo.
Aboriginal origins
Humans are thought to have migrated to Northern Australia from Asia using primitive boats. A current theory holds that those early migrants themselves came out of Africa about 70,000 years ago, which would make Aboriginal Australians the oldest population of humans living outside Africa.
Outside of Africa, Australia holds some of modern humans' earliest archeological evidence, with relics dating back to about 45,000 years ago.
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 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.
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.
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.
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.

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.
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.

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.
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.
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.
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.
While Indigenous Australians have inhabited the continent for tens of thousands of years, and traded with nearby islanders, the first documented landing on Australia by a European was in 1606. The Dutch explorer Willem Janszoon landed on the western side of Cape York Peninsula and charted about 300 km of coastline.
Humans moved from Southeast Asia onto this landmass, some settling in what is now New Guinea, others traveling farther south into Australia. They kept to the coastlines until they reached southern Australia 49,000 years ago.
The oldest human fossil remains found in Australia date to around 40,000 years ago – 20,000 years after the earliest archaeological evidence of human occupation. Nothing is known about the physical appearance of the first humans that entered the continent about 50,000 years 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.
There are 468000 Aboriginals in total in Australia in which 99 percent of them are mixed blooded and 1 percent of them are full blooded.
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.
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).
At the 2021 census, the number of ancestry responses within each standardised group as a proportion of the total population was as follows: 57.2% European (including 46% North-West European and 11.2% Southern and Eastern European), 33.8% (including 29.9% Australian) Oceanian, 17.4% Asian (including 6.5% Southern and ...
“An Australian Aboriginal genome does not exist and therefore to even propose that a test is possible is scientifically inaccurate,” Ms Jenkins said. “The two companies which currently offer this 'service' use sections of DNA called single tandem repeats (STRs) that vary in the number of copies each person has.
