The 6,000-Year-Old People Found Near Bogotá — And The DNA Test That Revealed A Native American Lineage That Vanished From The Genetic Record
The first Americans came from Asia.
This basic fact has been established by multiple independent lines of evidence — genetics, archaeology, and linguistics — and is not seriously disputed.
The specific route was the Bering land bridge: a broad swath of land, hundreds of miles wide from north to south, that connected what is now Siberia to what is now Alaska during the last Ice Age, when global sea levels were much lower because so much of the world’s water was locked in glacial ice.
This land connection — geologists call it Beringia — enabled the migration of people from northeastern Asia into North America at some point during the late Pleistocene.
