<pre>DNA studies revealed a previously unknown Native American population

A few years ago in the central part of Alaska were found the fossilized remains of a girl, whose “age” totals approximately 11,500 years. Thanks to the research of her DNA, it was possible to reveal another page in the history of migration of people to the territory of North America, as well as to learn about the existence of a previously unknown human population called “ancient Beringians.”

According to the generally accepted theory, it was formerly believed that people migrated from Asia to North America about 15000-30000 years ago on the Isthmus of Beringia, then still connecting the shores of the two continents.

Recent discoveries revealed both typical and previously unknown descendants of ancient people, which surprised scientists who expected to find a genetic profile that corresponds to the modern indigenous inhabitants of North America. The research of the girl's DNA showed that she belonged to a previously completely unknown population of people having nothing to do with those who then settled throughout the continent.

Scientists have put forward two possible theories explaining the results of research. According to the first, more than 15,000 years ago, two groups of people moved to America by an isthmus. According to the second, it was one group, then divided into two completely independent populations.

However, the results of genetic sequencing still speak in favor of the second version, with the genetic isolation of the ancient Beringians for many thousands of years still remains a mystery.

The study also refers to the so-called back migration of Native Americans to Alaska about 6,000 years ago, which completely absorbed or displaced the Beringians, resulting in the formation of the population of modern Alaska – atabaski.
