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
At this point in the story, it is worth stepping back and considering what the 2025 Science Advances paper actually changes in our understanding of South American prehistory.
Before this study, Colombia was a blank space in the ancient DNA map of the Americas.
The country that sits at the junction of Central and South America — the geographic entry point into the larger continent — had yielded zero published ancient human genomes.
This was not because Colombia was archaeologically unimportant; the opposite was true.
It was because the environmental conditions had made ancient DNA work difficult, and because the scientific infrastructure to conduct such work had not been available in Colombia.
The 2025 study changed all of that simultaneously.
