Milk teeth show previously unknown Siberian people from the Ice Age

Siberia was inhabited by humans for around 40,000 years, and the analysis of new genomics achieved by restoring ancient milk teeth provided clues to parents who lived there.

For the new study, published this week in the journal Nature Communications, the researchers analyzed DNA samples from 34 people identified by the Russian site Yana Rhinoceros Horn, an archaeological site in northern Siberia. The oldest human remains, two deciduous teeth, were 31,000 years ago. The scientists also analyzed DNA from the remains of 10-year-old youth.

Analysis shows that ancient northern Siberians have survived very coldly and survived mammoths, feathered rhinos and bison.

“These people are an important part of human history, they are almost the same as the ancestors of modern Asians and Europeans and may eventually occupy large areas of the northern hemisphere,” Eske Willerslev, a professor at Cambridge University.

Scientists also use DNA from modern populations to analyze the evolutionary history of ancient ruins. Modern and ancient DNA analysis shows that people in northern Siberia were closer to Europeans than Asians. Durable and adaptable populations in the Eurasian region emigrated around 40,000 years ago shortly after the European and Asian lines diverged.

According to the authors of the new study, the ancient Siberian genome was a “genetic mosaic” of people from northern Eurasia and America. Scientists believe that the earliest native groups in North America were descended from people from northern Siberia.

“The remnants are genetically very similar to the ancestors of Paleosiberian speakers and close to the ancestors of American Indians,” said Vilerslev, director of the “Lundbek” Geogenetic Foundation Center at the University of Copenhagen. “This is an important part of this puzzle to understand the ancestors of Indians, as you can see the signatures of Colima in Indian and Paleo-Siberian languages. This person is the missing link of Indian ancestors.”
