Researchers from all over the world want to be better understood by ancient humans. University of Oxford scientists have found some interesting discoveries about the first human species. Neanderthals and Denisovans think they were living in a cave in southern Siberia.
Oxford Radiocarbon Accelerator Unit Professor Tom Higham has collaborated with researchers from all over the world, including U.K., Russia, Australia, Canada, and German scientists. Five years after, there is a Densiova cave beneath the Siberia Altai ridge. It is the only archaeological site in the world, as it was occupied by various human groups. Now, two new studies published in the journal Nature Neanderthals and Denisov all lived together in the cave at the same time. The researchers say they also clarified their studies when they lived in environmental conditions when they disappeared.
Denisova caught the attention of the world In 2010, a study demonstrated that a genome believed that the girls were considered an unknown human team. In this way, the DNA of the Denisovans group DNA was sequenced for the first time. New research shows what groups have experienced with other ancient human species, such as Neanderthals, radio carbon bones, teeth and coal parts, within the PalaeoChron project of the European Research Council.
Researchers at the University of Wollongong in Australia discovered more than a hundred years in this sediment; Many of them were too old to make radio dates. A group of other Australians made dates of the uranium series, according to scientists, that they should find the minimum age according to the part of the bone, the Neanderthal / Denisovan ancestor.
"This is the first time it is able to allocate age enough to archeology of the cave and its contents," Higham said in a statement.
Determining the age-old age of the bone fragment was difficult with not enough radio dams. Scientists set up a new Bayesian model, forecasting estimates and genetics estimated by Denisovan and Neanderthal fossils. The second method was studied in the German Mitochondrial Anthropology at the Max Planck Institute, studying the DNA mitochondrial sequences.
"This new chronology of Denisova Cave offers a chronology, thanks to the richness of our Russian colleagues, in the last three crystalline cycles of archaeological and environmental history of the cave," said Zenobia Jacobs, an author of optical dating, at the University of Wobong.
Researchers believe the Neanderthal and Denisovans discover that they lived together in the cave for at least 200,000 years ago. Moreover, at that time, they used stone tools, so scientists believe that human occupation at the site began at least 300,000 years ago. Scientists say that Neanderthals live in southern Siberian territory for 200,000 to 100,000 years and lived with a girl named "Denny". hominins It is believed to have been collected and reproduced around 100,000 years ago.
