Colombia occupies the geographic position that makes it most important for understanding how the Americas were populated south of the isthmus.

Any population movement from Central America into South America passed through Colombian territory.

Any understanding of the early divergence of South American populations from a common ancestral source requires data from the northern end of the continent where that divergence would have begun.

Yet for most of the history of ancient DNA research, Colombia remained unstudied.

The practical challenges were real — tropical preservation conditions, the logistical difficulties of sampling archaeological material in a country with its own complex history of conflict and institutional constraints, the limited availability of research funding for work in a region that lacked the established international research infrastructure of, say, northern Europe or North America.

The 2025 study overcame these obstacles through the specific combination of Colombian and international researchers, institutional access through the Universidad Nacional de Colombia, and the technical capabilities of the Senckenberg Center.
