15.000 Jahre auf einem Kontinent, der heute unter Wasser liegt

It was once possible to walk from Siberia to Alaska—on foot, without a single boat. The area where the icy Bering Strait lies today was a separate subcontinent. And the DNA of present-day Native Americans suggests that their ancestors may have lived there for thousands of years before settling the rest of the double continent. This video explains the Beringian Standstill Hypothesis: what genetics supports it, why it is still debated scientifically, and why the actual setting of this story is now underwater.

"Genomic evidence for the Pleistocene and recent population history of Native Americans." Science, 349(6250). Recent genomic analyses suggesting a shorter isolation period (approximately 8,000 instead of 15,000 years). Note on scientific context: The genetic evidence for a longer isolation period on or near Beringia is now considered relatively well-established, although estimates of the exact duration vary between different studies (approximately 8,000 to 15,000 years). Direct archaeological evidence of settlements in the now largely submerged core area of ​​Beringia remains rare, as much of the relevant area is below sea level. This remains an active field of research. Subscribe to Survival Code for more stories about how vanished landscapes continue to shape our genetic history. #Archaeology #Genetics #Anthropology #Science
