Detecting ice age people in Siberia through milk teeth

Humans have been living in Siberia for about 40,000 years, and a new genetic analysis has been made through the discovery of ancient baby teeth that will bring about the knowledge of ancient humans who lived here.

In the new study, published in Nature Communications this week, the researchers analyzed DNA samples of 34 individuals discovered at Russia's Yana Rhino Horn Spot , an archaeological site in the northeast. Siberia. The oldest human remains, two baby's milk teeth, date from 31,000 years ago. Scientists also analyzed DNA from a 10,000-year-old remains of a young man.

People in northern Siberia are more closely related to Europeans than Asians.

Analysis showed that the ancient people of northern Siberia endured extreme cold and survived by hunting mammoths, hairy rhinos and Bison bison.

Eske Willerslev, professor at Cambridge University, said: 'These people are an important part of human history, they diversify almost at the same time as the ancestors of modern Asians and Europeans, and It is possible that at some point, they have lived in large areas of the northern hemisphere '.

Scientists also use modern human DNA to analyze the evolutionary history of ancient posthumous relics. Modern and ancient DNA analysis shows that people in northern Siberia are more closely related to Europeans than Asians. Strong and adaptable people migrated from Eurasia to the region from about 40,000 years ago, shortly after European and Asian lineages branched.

According to the authors of the new study, the ancient Siberian genome represents a 'genetic mosaic' of people coming from the north of the Eurasian continent and the Americas. Scientists estimate the earliest indigenous groups in North America are descendants of people living in northeastern Siberia.

Willerslev, director of the Lundbeck Genetic Center at the University of Copenhagen, said: 'These remains are very close to the ancestors of Paleo-Siberian speakers and close to the ancestors of Native Americans. It is an important piece in understanding the ancestors of Native Americans because you can see signs of Kolyma in Native Americans and Paleo-Siberians. This person is the missing link of the Native American ancestors'.
