For generations, we were taught that the first Americans arrived by crossing a frozen land bridge from Siberia and trekking through an “ice-free corridor” into the heart of North America. But new groundbreaking DNA evidence has rewritten that story. Scientists studying ancient environmental DNA from the once-frozen corridor in Canada have uncovered when life — plants, animals, and ecosystems — actually returned after the Ice Age. Their findings reveal that this corridor wasn’t open to humans until long after people were already living deep within the Americas.
This discovery challenges the traditional “Clovis-first” theory and strengthens the case for a daring coastal migration — where early seafarers followed the Pacific shoreline thousands of years before the ice melted. Join us as we explore how ancient DNA, buried in glacial sediments for over 15,000 years, is transforming our understanding of the first Americans and the routes they took to reach a new world.
