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.
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.
On the grand scale and going as far back in time as to shortly after modern humans migrated out of Africa the DNA-sequences show that together the Aboriginal Australians and Papuans split from Europeans and Asians about 58,000 years ago.
A new study of Indigenous Australian DNA suggests there was some form of migration from India to Australia about 4,000 years ago. Aboriginal people first inhabited Australia about 40,000 years ago and researchers had previously thought them to be isolated from the rest of the world for thousands of years.
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.
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.
Flow of genes suggests continent was not isolated after all. 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.
About 90% of Aboriginal communities today speak languages belonging to the “Pama-Nyungan” linguistic family. The study finds that all of these people are descendants of the founding population which diverged from the Papuans 37,000 years ago, then diverged further into genetically isolated communities.
In the early 19th century a small number of Indians arrived in Australia as convicts transported by the British colonial government in India. Others arrived as labourers with British subjects who had been living in India.
According to Australian records, a small group of Indians arrived in Australia in the years 1800-1816, sent as convict labourers by British colonial authorities.
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.
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.
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.
A new genomic study has revealed that Aboriginal Australians are the oldest known civilization on Earth, with ancestries stretching back roughly 75,000 years.
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.
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.
Many Indians can speak good English, the climate here is similar to their homeland and they're impressed with the country's economic infrastructure. An Australian university education is highly regarded and Indians are generally high achievers.
The Indians in Australia are predominantly male, while the Chinese are majority female." Indians are the largest migrant ethnic group in Melbourne and Adelaide, fourth largest in Brisbane, and likely to jump from third place to second place in Sydney by 2021.
India has overtaken China and New Zealand to become the third largest country of birth for Australian residents, 2021 census data has found. On 10 August 2021, 673,352 people living in Australia reported India as their country of birth – an increase of 220,000, or 47.9% per cent, since the previous census in 2016.
We show that Aboriginal Australians are descendants of an early human dispersal into eastern Asia, possibly 62,000 to 75,000 years ago. This dispersal is separate from the one that gave rise to modern Asians 25,000 to 38,000 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 Australian aboriginal people are descended from the original Dravidian peoples who first traversed the Indian sub continent and moved through the Malayan peninsula and the Indonesian island chain, largely on dry land, finally crossing the Wallace divide and arriving in Australia at least 65,000 years ago.
The word Indian came to be used because Christopher Columbus repeatedly expressed the mistaken belief that he had reached the shores of South Asia. Convinced he was correct, Columbus fostered the use of the term Indios (originally, “person from the Indus valley”) to refer to the peoples of the so-called New World.
Indigenous Peoples refers to a group of Indigenous peoples with a shared national identity, such as “Navajo” or “Sami,” and is the equivalent of saying “the American people.” Native American and American Indian are terms used to refer to peoples living within what is now the United States prior to European contact.
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.
