Early people lived before 160'000 years ago in the highlands of Tibet

The so-called Denisova-human has lived before 160'000 years ago in the highlands of Tibet. Scientists have a lower jaw that had been discovered on the 3300 meters of altitude, the contemporaries of Neanderthal man map, as it says in a Wednesday article published in the journal "Nature". This is evidence that the Denisovaner was long used before the modern people to life in oxygen-poor altitudes.

The discovery was a "Surprise", writes the Team of researchers, led by Jean-Jacques Hublin from the Max-Planck-Institute for evolutionary anthropology in Leipzig, Germany. You provide the proof that the Denisova man was not only in Siberia, but also in China.

It is the first discovery of the Remains of the Denisova people outside the eponymous cave in Siberia, where he was discovered in 2010, for the first time. Together with the Neanderthals, the denisovans are living the closest extinct Relatives of living people.

lower jaw already in 1980

discovered Originally, it was discovered the lower jaw in 1980 by a monk in the Baishiya cave in Xiahe in the South-Eastern Chinese province of Gansu. The cave is a Buddhist sanctuary. The monk gave his Fund a high Buddhist carrier, who in turn passed them to the Lanzhou University-wide. There he remained unnoticed.

Now analyzed researchers proteins of the Molars, located on the pine - a new method, developed by the Team of Hublin. They found out that the owner was of the mandible closely with the Denisovanern in Siberia related. A DNA analysis had initially produced no results.

It was a "extremely robust" jaw "very large teeth," said Hublin. The owner had a "receding chin" and was likely to have been a teenager. He had anatomical features with Neanderthals, and the Denisova-cave in common.

Four times older than thought

That is already in front of 160'000 years ago, early humans in this amount lived, no one can imagine, said Hublin. A the end of 2018 in the journal "Science" published study had shown that in front of 30'000 to 40'000 years, people in the Tibetan-lived on high land. "Now we have a Fund that is four Times as old, and it is not a modern Homo sapiens," said Hublin.

The Denisovaner have used, therefore, long before the Homo sapiens to the low-oxygen environment. A special Gene that enabled them, with low oxygen concentration, a Gene that is also a feature of the present inhabitants of Tibet to deal. Traces of Denisova DNA is found in the genome today, people live, particularly in Tibet, but also in Australia and Melanesia.

The researchers want to compare the jaw bone with other, not yet identified finds from China. "My hypothesis is that it is a large part of the fossils from China or East Asia, which are more than 50'000 years and younger than 350'000 years, probably denisovans," said Hublin. (anf/afp)
