![]() Their analysis also revealed a previously unknown connection between Native Americans and people who were living in Kamchatka a few centuries ago. Siberia was once a hotbed of migration that put ancient Siberians in contact with populations as distant as Japan and Greenland, the researchers found. These sequences were the first ancient DNA samples to come out of the remote peninsula, Posth says. The study also included genomes from three people who lived on the Kamchatka Peninsula-which dangles down from the Russian Far East well to the southwest of the Bering strait-just 500 years ago. The oldest of these samples dates back 7,500 years. ![]() Hoping to reconstruct this part of the region’s history, Posth and his colleague’s sequenced DNA from 10 ancient people whose remains were unearthed at various sites around Siberia. ![]() Little is even known about how people moved around within Siberia in the past few thousand years. And a small number of archeological finds in Alaska-including the discovery of 15th-century glass beads that may be of Venetian origin-have pointed toward ongoing trade between North America and the rest of the world.īut how far from the strait these ties extended is unclear. A 2019 study found genetic evidence that ancient people living on opposite sides of the Bering Strait were in contact with each other. Genetic studies and archaeological digs indicate that people from Siberia made the move into North America several more times, including as recently as 1,000 years ago.īut even though a lot of research has focused on reconstructing the arrival of people into what is now Alaska, “very little is known about migration in the other direction,” Posth says. This transcontinental highway succumbed to rising sea levels sometime between 11,000 and 10,000 years ago, but that didn’t stop migrations between the landmasses. Hypothesized dates vary widely, but many researchers agree that the earliest migrants likely traveled across the Bering Land Bridge, a strip of land that periodically connected northern Asia to modern-day Alaska in prehistory. “There is usually some back and forth.”Įxactly when and how people first arrived in the Americas is one of the longstanding debates in archaeology. “Human movement is rarely unidirectional,” says the new study’s co-author Cosimo Posth, an archaeogeneticist at the University of Tübingen in Germany. This American heritage-still present in the genomes of some Siberians today-adds to a scattering of archeological evidence suggesting that North Americans were in contact with their northern Asian neighbors for thousands of years before Europeans arrived. But new evidence now shows that these early migrations weren’t one-way trips: in a study published on Thursday in Current Biology, researchers say they have uncovered traces of Native American ancestry in the DNA of Siberians who lived centuries ago.
