Scientists using sophisticated methods to determine the age of bone fragments, teeth and artifacts discovered in the Siberian Cave have provided a new insight into a mysteriously extinct human species that may have been more developed than previously known.
In a study published on Wednesday, the light manifests itself in Denisovans species known only from the remains of the Denisov Cave at the foot of the Altai Mountains in Russia.
Although there is still a riddle, our species, Homo sapiens, especially among the Papua New Guinea and Australian indigenous peoples, has left a genetic mark that retains a small but significant portion of Denisovan DNA, indicating previous species.
Fossil and DNA traces that showed that Denisovans were in the cave for at least 200,000 to 50,000 years, and the Neanderthals who were closely related to extinct human species were there between 200,000 and 80,000 years ago, discovered the new study. Stone tools pointed out that one or both species may have found beer from 300,000 years ago.
Scientists last year described a fragment of Denisov's cervical bone from a girl whose mother was Neanderthal and father Denisovan, about mutual sorting. The girl, called "Denny", lived about 100,000 years ago, the new study showed.
Pendants made from animal teeth and bone points were found to be between 43,000 and 49,000 years old. They may have been developed by Denisovan, pointing to intellectual sophistication.
"Traditionally, these objects in Western Europe are linked to the expansion of our species and are seen as signs of behavioral modernity, but in this case Denisovans may be their authors," said Archaeologist Katerina Douka of the Max Planck Institute of Science. Human history in Germany.
Our species originated in Africa about 300,000 years ago, later spread around the world. There is no evidence that these items were in the Denisov Cave.
Denisovans are known only from three teeth and one toe.
"The new fossils would be particularly welcome because we know almost nothing about Denisovans' physical appearance, except for those who have quite heavy teeth," said Wollongong University's Australian geochronologist Zenobia Jacobs.
"Their DNA among today's Australian aborigines and the New Guinea population is impressively suggesting that they can be quite widespread in Asia and possibly even in Southeast Asia, but we need to find some evidence of their presence in these regions to improve the complete story of Denisovans," he added. Wollongong University Geochronologist Richard Bert Roberts.
The study was published in a journal Nature.
