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
But their place in the genetic landscape of the Americas was unknown.
They were, in the language of population genetics, an uncharacterized lineage — a group whose specific position in the family tree of South American populations had never been determined.
Now it has been.
The Checua individuals from the Bogotá Altiplano, the seven hunter-gatherers who lived on that high Colombian plateau roughly 6,000 years ago, have been placed — with all appropriate scientific uncertainty — in the family tree of the Americas.
They were early South Americans who took an independent path from the common ancestor they shared with other South American populations.
