The site preserves evidence of the transition from hunter-gatherer to agricultural settlement on the plateau.

Las Delicias and Soacha provided Muisca-period individuals.

The Soacha site — from the municipality of the same name, just south of Bogotá — is associated with the late Muisca period, roughly 500 years before present, and thus overlaps with the earliest Spanish contact.

The Las Delicias site represents the earlier Muisca period, approximately 1,200 years before present.

The Purnia site in the Los Curos area provided the two Guane individuals, extending the study’s geographic scope northward from the Bogotá basin.

The five-site approach allowed the researchers to construct their genomic time series — their “transect” — tracking genetic change across the full documented period of Altiplano occupation in their dataset.
