Homin’s jaw found in Taiwan in 2015 has discovered a scientific team Tenisovano male of the late Pleistosene. Innovation not only extends the lower fossil record of this species, but also proves that the group lived in a vast Asian region with a variety of climate. Details of the study led by University Scientists at the University of Copenhak (Denmark) and Advanced Chochendai Studies in Japan were published in the newspaper on Thursday Science.
About 50,000 years ago, the Homo Sabians lived with other homeinine people, such as neontrivals. These people are well described thanks to the numerous fossils found in Europe and Asia. One of these homininos is the man of Tenisova, Found a decade ago, no residues in them. The human species was found for the DNA analysis of some of the remnants described in 2010 in Qua Denisova (Siberia).
The Paleiogenic study revealed that these men were different from all that were known to be different. Similarities with neonterties Because the two had a common ancestor, from which they separated 400,000 years ago. From there, the neontrons formed in the western half of Eurasia and Tenisovanos, and Oceania.
They are found in different parts of the world
In fact, many genetic studies show that Wide parts of East Asia.
Over the past decade, new residues of Tenisovanos appeared, in the Qua de Denisova (two teeth) and Tibet After analysis of (a jaw and ribs), proteiumic studies (fossil protein analysis) were reserved for this human species.
However, the fossil record of Denisovanos is not enough to determine their appearance and anatomical aspects, but published works Science “Open an important door in the study of human evolution ”.
His invention reveals that they came to Asia
The jaw was found in 2015 in the seas of the Pengu Canal in Taiwan The oldest homeinine fossil of that Chinese island But at the time, they could not analyze the DNA. Now.
Innovation is important Impacts on evolutionary history in Oriental Asia: Denisovanos reached Southeast Asia and occupied a very vast geographical part of Siberia, Tibet, Taiwan or Laos “, which is very important, living in very different situations, from the first most important environment in the Siberian cold, the most important of the most concept of the most continental, such as the most concentration of China.
But. Rosas says, “In the coming years, we will see the clear configuration of those fossils that we do not know in Asia, and it will clarify the panorama of human evolution on that less known continent,” says Rosas.
Parallel, “this jaw, which is This is more complete than other previous residues, which will help you create physical appearance for that group The man we know only through the genetic line of man is, “Rosas stands alone.” Therefore, it can be compared with the jaw or the teeth of the Denisova cave in Tibet, and for example, with the remnants found in the Chinese cave of the skull bones. All of this will allow you to start learn more about its anatomy. This discovery also opens the full range of possibilities, ”he briefly.
“They are still very mysterious homenins”
As for the Carlos Laluvesea-box for the Paleiogenic (IBE) of the evolutionary biology company, this discovery not only expands the climate and geographical distribution of Tenisovanos, but also provides their metaphoric and new sources This shows that the jaws of these hominins were very strong and had large teeth Than neontroles or chapels. Like Rosas, Lalusea-Fox believes, “The interesting thing is to look at the Chinese fossil record and see if there are residues that fit this profile.”
“Of course, those who are not, they should ask what they can be if they are not Denisovanos,” he explains to EFE. Also, despite its enormous geographical distribution, “They are still very mysterious homenins”IBE concludes the researcher.
