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 skull is markedly dolichocephalic and about 20% smaller in cranial capacity than the European. It has two special archaic features — heavy brow ridges and the nasal notch. The latter involves a retreating glabella as well as a depressed root of the nose and sunken orbits.
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.
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.
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.
A new genomic study has revealed that Aboriginal Australians are the oldest known civilization on Earth, with ancestries stretching back roughly 75,000 years.

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.
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.
Some researchers have posited that the ancestors of the Aborigines were the first modern humans to surge out of Africa, spreading swiftly eastward along the coasts of southern Asia thousands of years before a second wave of migrants populated Eurasia.
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.
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.
Results: The Aboriginal and non-Aboriginal populations had significantly different ABO and RhD distributions (P < 0.001). 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.
For Aboriginal and Torres Strait Islander people, avoidance of eye contact is customarily a gesture of respect. In Western society averting gaze can be viewed as being dishonest, rude Page 2 or showing lack of interest.
In NSW Aboriginality determined through the Commonwealth Government definition can be confirmed through a Letter of Confirmation of Aboriginality or a Certificate of Aboriginality.
The average male stature was 1,712 mm, and the average female stature was 1,567 mm. Data collected by Wood Jones and Campbell in 1924 for Aboriginal South Australians show that young adult male stature was 1,668 mm (n=6), and female stature was 1,552 mm (n=4).
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.
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.
Based on the Australian Bureau of Statistics (ABS) projections, the number of Indigenous Australians in 2021 was estimated to be 881,600.
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 ...
Thus it appears that both sexes of the two regions, the desert and the coastal, of the present study fall within the range of variation of hair forms of the Australian aborigines. Campbell et al. (1936-37) found curly hair with a frequency of 7.89%.
Now a study has turned up evidence of much more recent interbreeding between native Australians and people who came from India. The findings, based on a detailed examination of the DNA of aboriginal Australians and hundreds of people of other pedigrees, found that mixing occurred as recently as 4,200 years ago.
Scientists are still debating on the cause of the blonde hair in Aborgines. Some of them say, the blonde hair is caused by mixing with Europeans during colonization. Others say it is due to a genetic mutation.
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 data show that Aboriginal Australian Y chromosomes are very distinct from Indian ones. These results refute the previous Y chromosome study, thus excluding this part of the puzzle as providing evidence for a prehistoric migration from India.
