An international research group, discovered in the last Ice Age, has been discovered by an international research team with DNA testing of two milk teeth found at a Northeast Siberian archeological site.
The researchers reported the results of a dental examination in a major study of genetic analysis of a 10,000-year-old human residue found at another Siberian site. The analysis showed a close genetic relationship with indigenous Americans. A finding of such a close relationship was first discovered outside the United States, reports ScienceDaily.com.
Eske Willerslev, Head of the International Research Group, Professor at Cambridge University and Director of the Lundbeck Geogenetic Foundation at the University of Copenhagen, named the new folk the name of the ancient North Siberians, stressing that this group of people played a significant role in human history.
Last year, the two milk teeth were discovered on an archaeological excavation near the Russian River Jana. The archaeological site called RHS was discovered in 2001. More than 2,500 finds, animal bones and stone tools indicating human presence have been discovered.
According to a study published in the current issue of the Nature magazine, the ancient Siberian population lived in the area 31 thousand years ago, hunting for woolly mammoths, rhinos and bison.
According to Willerslev, this group of people developed almost simultaneously with the ancestors of modern Asians and Europeans, and there was a time when it was likely to populate large areas of the northern hemisphere.
Martin Sikora, the leading author of the study, said that the group was very quickly used to extreme conditions and quickly migrated. The discovery of the group is changing not only the people living in northern Siberia, but also the picture of the migration of human history, he added.
Researchers believe that a group of 40 people, with a population of 500, could live around the archaeological site.
The authors of the study examined and compared DNA samples from 34 human remains found in North Siberian and Central Russian excavations. As a professor at the University of Bern, Laurent Excoffier pointed out, it is remarkable that the ancient northern Siberians were more closely associated with Europeans than the Asians, and they seemed to emigrate immediately from the western part of Eurasia after the separation of Europeans and Asians.
It is widely accepted that the first people from Siberia to Alaska arrived in America when they were able to cross the former Bering land bridge at the end of the last ice age. The researchers have shown that the ancestors of these people were Asian groups that were mixed with the ancient North Siberians.
The discovery was supported by DNA analysis of the remains of the tens of thousands of years old man at the Kolima River in Siberia. Among the ancestors of the man were ancient North Siberians and East Asians, and this genetic mosaic is very similar to the genus found in the indigenous Americans. “This man is the missing link to the ancestors of indigenous Americans,” said Willerslev.
