Scientists have long held to the consensus that almost every single person on the planet is descended from the first human beings who left Africa between 40,000 and 100,000 years ago.
There is still a great deal that geneticists and other scientists and researchers do not understand about this pivotal moment in human history and it appears that research into the topic is raising more questions than answers.
A New Branch Of Humanity
Researchers from Harvard Medical School have recently released the findings of a comprehensive study of the human genome from all areas of the world, and they have discovered something astonishing about the Australian Aborigine population – they appear to have genetic markers which indicate that they are descended from a still unidentified form of human being.
‘Our main goal is to understand how our race came to the point where it is today, and for that, we must first study the DNA of ancient tribes, ’ explained Mallick Swapan who led the study and has been actively researching the origins of the human genomes for the majority of his career. He explained that the new study gathered together the genetic data of 280 different human populations scattered across the world who had been under-represented in this form of study until now.
According to Swapan, the most incredible revelation of this new study is that the genetic code of Aboriginal Australians demonstrates that they carry the DNA markers that indicate ancient interbreeding with an unidentified branch of humanity. While it was originally suspected that the unusual DNA markers might indicate that the ancestors of the Aboriginal people interbred with the elusive ancient species known as the Denisovians, this hypothesis proved to be incorrect. After analysis, the scientists discovered that the DNA markers were distinct from Denisovian markers leading them to the conclusion that they had discovered the traces of an entirely new form of ancient human species.
The indigenous people of Australia are known to be descended from the first people who arrived on the continent from Africa approximately 50,000 years ago. It has been assumed that the aborigine people were isolated from the rest of the world for thousands of years and therefore the scientists assumed that their genetic code would be fairly homogenous. Surprisingly, this turned out not to be the case. “The genetic signatures of an Aboriginal Australian from eastern Australia and from Western Australia are as different as the ones of a person from Europe and a person from Asia, ” said Swapan.
The incredible diversity in the genetic code of the native people of Australia in addition to the peculiar marker which indicates that they interbed with an unknown human species in the past indicates that there is still so much more to discover about the ancient history of humanity.
