FfFfFfFF 58,120 Posted June 6, 2021 Share Posted June 6, 2021 An international research team determined that ancestors of modern domestic horses and the Przewalski horse moved from the territory of Eurasia (Russian Urals, Siberia, Chukotka, and eastern China) to North America (Yukon, Alaska, continental USA) from one continent on another at least twice. “We found out that the Beringian Land Bridge, or the area known as Beringia, influenced genetic diversity within horses and beyond,” said senior researcher at the Ural Branch of the Russian Academy of Sciences and the Ural Federal University (Russia) Dmitry Gimranov. “Owing to the appearance of this land part, the flow of genes among mammoths, bison, and wolves could occur regularly. And if 1-0.8 million years ago horses from North America were not yet widespread in Eurasia, then in the periods of 950-450 and 200-50 thousand years ago, there was a bidirectional spread of genes over long distances.” In other words, horses migrated between continents not only in one direction but also vice versa. The first wave of migration was predominantly from North America to Eurasia. The second migration was dominated by the movement from Eurasia to North America. To determine the area of settlement of horses, molecular biologists studied horses’ DNA from both continents. From 262 samples of bones and teeth, they selected 78 with sufficient DNA. Researchers conducted radiocarbon dating and genetic analysis at the Denmark and USA laboratories. In addition, they looked at the research data from 112 samples.
