Ancient DNA Reveals People Lived at Gateway Between the Americas

Ancient DNA from Colombia has revealed a surprising mystery: people living near Bogotá 6,000 years ago do not fit known genetic patterns of ancient North or South Americans. About 4,000 years later, this group vanished from the genetic record, replaced by a different population. Scientists are unsure what happened—whether they mixed, moved, or remain undiscovered. This finding highlights the complexity of human migration into South America and shows that DNA alone cannot tell the full story, emphasizing the importance of culture, language, and oral history in understanding our past.
