“Genetics tell the story of how the Americas were populated by the ancestors of modern Indigenous people. Their origins lie in Siberian and East Asian groups who are thought to have first mixed 20,000 years ago, during the Late Paleolithic, later crossing a bridge of ice to North America some 16,000 years ago. It was then that this lineage split into northern Native American and southern Native American lines.”
