Overview
- The Picuris Pueblo tribe collaborated with geneticists to confirm a direct ancestral link to Chaco Canyon through DNA analysis of 16 ancient and 13 modern individuals.
- Published in Nature, the study marks the first Indigenous-led ancient DNA research, with the tribe retaining full control over data and methodology.
- Findings validate Picuris oral histories and challenge theories of a complete regional exodus after Chaco Canyon's decline around 1150 AD.
- The study provides new evidence for the tribe's efforts to influence policy debates over oil and gas drilling near the UNESCO World Heritage site.
- This collaboration sets a precedent for ethical partnerships between Indigenous communities and scientists, emphasizing respect and data sovereignty.
