"Our discovery confirms previous analyses and demonstrates that this is the earliest known site of human settlement in Canada," said Burke. “It shows that Eastern Beringia was inhabited during the last ice age."
According to Burke, previous studies in population genetics have shown that a group consisting of a few thousand individuals lived in isolation in Beringia – a vast region that stretches from the Lena river in Russia to the Mackenzie river in Canada – around 15,000 to 24,000 years ago.
Burke confirmed that their discovery verifies the “Beringian standstill [genetic isolation] hypothesis” that “during the Last Glacial Maximum, Beringia was isolated from the rest of North America by glaciers and steppes too inhospitable for human occupation to the West.”
This means the earliest human presence in North America can now be dated back to the last ice age. These people, potentially taking refuge in the Bluefish Caves, would therefore be the ancestors of the people who would colonize the entire continent.
