The authors of the new study, however, say a previously unidentified internal dispersal of Aboriginal people that swept from the northeast across Australia around that time led to the linguistic and cultural linking of the continent’s indigenous people. One possible answer has been that a second migration into Australia by people speaking this language occurred around 4,000 years ago. Scholars have long been flummoxed as to why the language spoken by 90 percent of Australia’s Aboriginal people is relatively young-approximately 4,000 years old according to language experts-if their ancestors had occupied the continent so much earlier. “Because the continent has been populated for such a long time, we find that groups from southwestern Australia are genetically more different from northeastern Australia, than, for example, Native Americans are from Siberians.” “The genetic diversity among Aboriginal Australians is amazing,” said Anna-Sapfo Malaspinas, one of the lead authors and an assistant professor at the Universities of Copenhagen and Bern. By 31,000 years ago, Aboriginal Australian communities became genetically isolated and started to diverge greatly from one another, likely due to the development of the inhospitable desert in the interior of the continent. The researchers theorize the break could have been attributed to early flooding of the Carpentaria Basin that left Australia connected to New Guinea by only a narrow, impassable strip of land. The study also found that Aboriginal Australians and Papuans diverged from each other about 37,000 years ago, although the reason is unclear because the water separation between New Guinea and Australia had yet to be completed. At that time, according to the study’s authors, Aboriginal Australians became genetically isolated, making it the world’s oldest civilization.Īboriginal hunter in the Australian Outback. “There may have been other migrations, but the evidence so far points to one exit event.”Īround 50,000 years ago, the wave of migration reached Sahul, a prehistoric supercontinent composed of present-day Australia, Tasmania and New Guinea prior to their separation by rising sea levels 10,000 years ago. ![]() “Our results suggest that, rather than having left in a separate wave, most of the genomes of Papuans and Aboriginal Australians can be traced back to a single ‘Out of Africa’ event which led to modern worldwide populations,” said Manjinder Sandhu, a senior author from the Sanger Institute and University of Cambridge, in a statement released by the university. While European and Asian ancestral groups became distinct in the genetic record around 42,000 years ago, the researchers say that occurred even earlier-approximately 58,000 years ago-in the case of indigenous Papuan and Australian ancestral groups as they ventured eastward. I have no question it was to bring the gospel of Jesus to them," Mr Staver said.While some scholars have theorized that indigenous Australians descended from a separate, earlier migration than that of Eurasian people, the study’s authors report that the majority of non-Africans stem from a single ancestral group of migrants who left Africa approximately 72,000 years ago and eventually spread across the other continents. Mr Chau went through that program in 2015. ![]() Mr Chau had wanted ever since high school to go to North Sentinel to share Christianity with the indigenous people, said Mat Staver, founder and chairman of Covenant Journey, a program that takes college students on tours of Israel to affirm their Christian faith. ![]() While special permits are required, scholars say visits are now theoretically allowed in some parts of the Andamans where they used to be entirely forbidden, including North Sentinel. India recently changed some of its rules on visiting isolated regions in the Andamans. Police surveyed the island by air on Tuesday (local time), and a team of police and forest department officials used a coast guard boat to travel there on Wednesday. "He ventured out on his own free will and his local contacts need not be persecuted for his own actions," the family said. The family also said it forgave his killers and called for the release of those who assisted him in his quest to reach the island. In an Instagram post, his family said it was mourning him as a "beloved son, brother, uncle and best friend to us."
