Scientists using sophisticated techniques to determine the age of fragments of bones, teeth and artifacts discovered in the Siberian Cave gave a new look to the mysterious extinct human species, which may be more advanced than before.
The research, which was released on Wednesday, sheds light on the Denisovans species, which is known only from the remains of Denis Cave at the foothills of the Altai Mountains in Russia.
While still mysterious, they have abandoned the genetic feature of our species, Homo sapiens, especially among native populations in Papua New Guinea and Australia, which have retained a small but significant percentage of DNA Denisovany, evidence of past species crossing.
Fossils and DNA traces have shown that the Denis were present in the cave at least 200,000 to 50,000 years ago, and Neanderthals, relatives of the extinct human species, were present there between 200,000 and 80,000 years ago, new research has emerged. Stone tools indicate that one or both species could have occupied the cave 300,000 years ago.
Scientists last year described Denis's cave bone fragment of a girl whose mother was Neanderthal and Father Denisovanem, a proof of crossing. The girl, nicknamed Denny, lived about 100,000 years ago, new research has shown.
Pendants from animal teeth and bone dots from the cave were found between the ages of 43,000 and 49,000 years ago. Denizens could have been created, suggesting some degree of intellectual sophistication.
"Traditionally, these objects in Western Europe are associated with the expansion of our species and are considered to be characteristic features of modernity behavior, but in this case their authors may be" Denis "," said the archaeological scientist Kateřina Douka of Max Planck's Institute for the History of Human History in Germany .
Our species originated in Africa some 300,000 years ago, later spread around the world. There is no evidence that Homo sapiens reached Denis cave when these objects were made.
The denizens are known only from three teeth and one finger bone.
"New fossils would be particularly welcome, because almost nothing we know about the physical appearance of Denisans, except that they have rather jagged teeth," said geo-chronologist Zenobia Jacobs of the University of Wollongong in Australia.
"Their DNA in modern Australian indigenous and new Guinean people suggests they can be fairly widespread in Asia and perhaps even in Southeast Asia, but we need to find some evidence of their presence in these areas so we can clarify the whole story of Denisovans," Geochronolog Richard "Bert" Roberts of the University of Wollongong.
