A few years ago, in central Alaska, the fossilized remains of a girl were discovered, the "age" of which is about 11, 500 years old. Thanks to the research of its DNA, it was possible to open another page in the history of human migration to North America, as well as to learn about the existence of a previously unknown human population called the “ancient Beringians”.
In accordance with the generally accepted theory, it was previously believed that people migrated from Asia to North America about 15, 000-30, 000 years ago along the Beringia Isthmus, then still connecting the shores of two continents.
Recent discoveries have identified both typical and previously unknown descendants of ancient humans, surprising scientists hoping to find a genetic profile that matches modern North American indigenous peoples. DNA tests of the girl showed that she belonged to a previously completely unknown population of people, having nothing in common with those who then settled throughout the continent.
Scientists have put forward two possible theories to explain the research findings. According to the first, more than 15, 000 years ago, two groups of people crossed the isthmus to America. According to the second, it was one group, then split into two completely independent populations.
However, the results of genetic sequencing still speak in favor of the second version, while the genetic isolation of the ancient Beringians for many thousands of years still remains a mystery.
The study also refers to the so-called reverse migration of Native Americans to Alaska about 6, 000 years ago, which completely absorbed or displaced the Beringians, as a result of which the population of modern Alaska - Athabasca was formed.
