the Neanderthals and Denisova-humans have not only lived together in Siberia, but over tens of thousands years, at least phase-wise is also the same cave.
The close mountains, two international teams of researchers from studies of the Denisova cave in the South Siberian Altai. Therefore, the two could have inhabited, closely related to the Homo sapiens relatives of the human species, this property even over a period of almost 150,000 years ago, long before modern humans reached the Region.
The result, however, does not necessarily imply that both species have shared the accommodation at the same time.

in the Altai mountains, located in Denisova cave will be researched for decades. Abruptly she became famous in 2010, when the analysis there, we found fingers pointed bone on a previously unknown species of human, the denisovans.
Later on, other teeth and bones were discovered, which originated from denisovans and Neanderthals. The analysis of the bone of a girl even revealed that the mother of the child Neandertalerin, the father denisovans were human. Modern humans populated Siberia to the present state of Knowledge it is only about 45,000 years ago.
Now, two international teams of researchers present in the journal “Nature” a chronology of the reference layers in the cave. A reliable chronology was so far, therefore, difficult, because the radio carbon Dating (C14), only up to about 50,000 years back.
finds from the cave, which were used for Dating.
encounters over 150,000 years
The Team of Katerina Douka from the Jena Max-Planck-Institute for the history of mankind, the age of the finds, calculated now on the basis of a statistical model, in the genetic analysis, thermo-luminescence Dating and the C14-Method was based.
Therefore inhabited Denisova people, the place in front of 200,000 up front may be about 50,000 years. Several Neanderthal fossils date back to the scientist in a time of 140,000 to 80,000 years ago. However, the researchers found Neanderthal genetic material in a layer of 190,000 years old.
This indicates that, “the fact that both groups lived for a period of almost 150,000 years in the Region, met and – on occasion – mixed,” writes the group. The long period of time Douka explains with other finds from the Region, according to which Neanderthal man lived there are still around 60,000 years ago. The girl, whose parents are Neanderthals and denisovans were human, lived according to the study, about 100,000 years ago.
Enigmatic finds of Bone points and pendants of animal parts
A second team of researchers to Zenobia Jacobs from the Australian University of Wollongong believes that Denisova people of the cave from about 300,000 years to before 55,000 years inhabited, Neanderthals, however, before 200,000 to 100,000 years ago.

remain a Mystery to the finds of Bone points and pendants made from animal parts, which are typical for modern people. Your age, the Team is determined to Douka to about 45,000 years.
The researchers suggest that the objects of Denisova-come people. To their manufacture but may also have contributed to modern humans, the Siberia had already achieved. Previous studies had already shown that also the Homo sapiens mixed with Neanderthals than with denisovans.
In a “Nature”-commentary by Robin Dennell of the University of Exeter refers to the uncertainty of the Dating. Nevertheless, the picture was now clear, he emphasizes: “The place was of denisovans and Neanderthals both in Cold – than in warm times, from 200,000 to 50,000 years ago inhabited.”
