New research changes understanding of the migration of ancient people

People have come to Australia from at least 65,000 years ago, 18,000 years earlier than ever calculated.

This is the result of a study published July 20 after archaeologists found axes and grindstones at a cave in Australia's far north.

Australian scientists have used the technique of antiquated age dating with radioactive carbon as well as laser beams. Ancient tools were found at a uranium mine in Rio Tinto, 300 kilometers east of Darwin.

The results of the study changed the understanding of the "invasion" of humans in the continent, leading to the formation of Aboriginal culture , which was supposed to start about 47,000 years ago.

The head of research Chris Clarkson said the results of the study also changed the scientific understanding of when people migrated from Africa, the cradle of humanity.

Until now, scientists still believe that people first leave Africa around the time between 100,000 years ago and 60,000 years ago. However, with humans appearing in Australia, the last point of this historic migration, from at least 65,000 years ago, the study opened up the possibility that people had left Africa earlier than this time.

Clarkson's article was published in Nature.

Last month, a study also published in this journal changed the understanding of human primitive origin. A human fossil discovered in Morocco dates back 300,000 years, about 100,000 years older than any fossil found before.
