The first major genomic study of Aboriginal Australians ever undertaken has confirmed that all present-day non-African populations are descended from the same single wave of migrants, who left Africa around 72,000 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.
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.
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.
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.
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.
A new genomic study has revealed that Aboriginal Australians are the oldest known civilization on Earth, with ancestries stretching back roughly 75,000 years.
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.
Aboriginal people are known to have occupied mainland Australia for at least 65,000 years. It is widely accepted that this predates the modern human settlement of Europe and the Americas. Increasingly sophisticated dating methods are helping us gain a more accurate understanding of how people came to be in Australia.
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.
The extensive study of Aboriginal people's DNA dates their origins to more than 50,000 years ago and shows that their ancestors were probably the first humans to journey across Asia and cross an ocean. The findings also show that these Aboriginal ancestors remained almost entirely isolated until around 4,000 years ago.

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 oldest human remains in Australia were found at Lake Mungo in south-west New South Wales, part of the Willandra Lakes system. This site has been occupied by Aboriginal people from at least 47,000 years ago to the present.
Australian Prehistory: Humans are thought to have arrived in Australia about 30,000 years ago. The original inhabitants, who have descendants to this day, are known as aborigines. In the eighteenth century, the aboriginal population was about 300,000.
From at least 60,000 B.C. the area that was to become New South Wales was inhabited entirely by indigenous Aboriginal and Torres Strait Islander peoples with traditional social, legal organisation and land rights. The population of New South Wales was at least 100,000 with many tribal, clan and language groups.
There is no one Aboriginal word that all Aborigines use for Australia; however, today they call Australia, ""Australia"" because that is what it is called today. There are more than 250 aboriginal tribes in Australia. Most of them didn't have a word for ""Australia""; they just named places around them.
In addition to traditional migratory patterns, various Aborigine groups and individuals migrated as a result of contact with Europeans. Early post-contact governments in Australia created reserves to which many Aborigines were "encouraged" to relocate.
NEW YORK (AP) — Scientists discovered the oldest known DNA and used it to reveal what life was like 2 million years ago in the northern tip of Greenland.
Evidence still suggests that all modern humans are descended from an African population of Homo sapiens that spread out of Africa about 60,000 years ago but also shows that they interbred quite extensively with local archaic populations as they did so (Neanderthal and Denisovan genes are found in all living non-Africa ...
Humans first evolved in Africa, and much of human evolution occurred on that continent. The fossils of early humans who lived between 6 and 2 million years ago come entirely from Africa. Most scientists currently recognize some 15 to 20 different species of early humans.
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.
Starting in 1794, mass killings were first carried out by British soldiers, then by police and settlers – often acting together – and later by native police, working under the command of white officers, in militia-style forces supported by colonial governments.
Prior to British settlement, more than 500 First Nations groups inhabited the continent we now call Australia, approximately 750,000 people in total. Aboriginal and Torres Strait Islander cultures developed over 60,000 years, making First Nations Peoples the custodians of the world's oldest living culture.
