Descendants Aboriginal India ?

A recent hypothesis posed to the researchers, the native Australian Aboriginal tribes from Asia, specifically India. 

Genetic study is written in the report of the National Academy of Sciences, and mentioned even dingo - a wild dog Australia - also brought by immigrants from India. The reason is because the fossil record estimates of wild dogs that arrived in Australia in the same time. 


This study shows that the DNA of indigenous Australian Aboriginal reveal the displacement of people from India about 4000 years ago. 

Researchers also estimate the probability of immigrants from India brought stone tools called microliths into their new residence. 

Whereas previously many experts believe the Australian continent isolated long enough, as explained Prof. Mark Stoneking, of the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany the following, "For a long time, it has been alleged about the early colonization, Australia isolated as a lack of sufficient evidence or contact with the outside world." 

In a study on the origins of the Australian population, the team compared the genetic material of Aboriginal Australia by people from Papua New Guinea, Southeast Asia and India. 

By observing specific location, which is called genetic makers, in the DNA sequences, the researchers were able to track the gene to determine who is most closely associated. 

They found a genetic association between the ancestors of Papua New Guinea and Australia, which are estimated to be around 35,000 to 45,000 years ago.At that time, Australia and Papua New Guinea is an island together, called Sahul, and relates to a period when humans first arrived. 

But the researchers also found genes with considerable amounts between India and Australia. 

Prof Stoneking said: "We get a clear signal to see a number of genes that assessors from all genetic links between India and Australia between the period of 4000 to 5000 years ago." 

He said that genetic data can not find the route to reach the Indian subcontinent, but it is proof that Australia is not disconnected as previously assumed. 

"Our results show that a person who gives a genetic contribution to the Australian people of India," explains Prof. Stoneking.
