A new study presents a theory that Indians arrived in Australia 4000 years ago and the genes had got mixed with that of Australian aboriginals. This was before the Europeans colonized Down Under.
Dingo, the Australian wild dog, may have also been an Indian export besides stone tool technologies that changed the way Australian aboriginals lives their lives.
Scientific evidence were presented as part of the study to prove the above theory.
A study by researchers from Germany, has now confirmed evidence of substantial gene flow between Indian population and Australia aboriginals about 4,000 years ago.
Interestingly, the study also suggests that this migration coincided with several changes in the archaeological record of Australia, which include a sudden change in plant processing and stone tool technologies, with microliths appearing for the first time, and the first appearance of the dingo in the fossil record.
The researchers from Germany explained that they have estimated the amount of Indian contribution to Australian genomes at around 10%, however its still not clear that how may Indians migrated as number would depend on then population of Australia.
Australia holds some of the earliest archaeological evidence for the presence of modern humans outside Africa, with the earliest sites dated to at least 45,000 years ago, making Australian aboriginals one of the oldest continuous populations outside Africa.
Now, researchers have analyzed genetic variation from across the genome from aboriginal Australians, New Guineans, island south-east Asians and Indians.
Dr Pugach said, “Our findings suggest substantial gene flow from India to Australia 4,230 years ago — during the Holocene and well before European contact. Currently the accepted view is that Australia has been completely isolated for almost 45 thousand years following its initial colonization in the late 1800s. Yet Australian archaeological record documents some changes which occur in Australia around — 4,000 years ago, which could have been potentially brought in from the outside.”
