Ancient DNA Unveils Genetic Link Between the Picuris Pueblo and Chaco Canyon, Strengthening Cultural and Historical Connections

(IN BRIEF) A study led by Eske Willerslev at the University of Copenhagen has revealed a genetic link between the Picuris Pueblo and Chaco Canyon, cementing their ancestral connection to this UNESCO World Heritage site. Using ancient DNA from bones and teeth, along with saliva samples from living Picuris members, researchers demonstrated the Pueblo’s ties to Pueblo Bonito in Chaco Canyon. The study highlights the importance of ancient DNA as a tool in archaeology and cultural preservation, helping indigenous communities validate their historical connections to sacred lands.

(PRESS RELEASE) COPENHAGEN, 5-May-2025 — /EuropaWire/ — A groundbreaking study led by Eske Willerslev at the University of Copenhagen has unveiled significant genetic links between the Picuris Pueblo people and their ancestral ties to Chaco Canyon, a UNESCO World Heritage site. The research, published in Nature, connects not only the Picuris Pueblo to their ancient ancestors but also emphasizes the sacred importance of Chaco Canyon, situated in the southwestern United States, for the Picuris people.

Using DNA extracted from fragments of ancient bones and teeth, dated between 500 to 700 years ago, along with saliva samples from contemporary Picuris Pueblo members, the team successfully demonstrated a genetic connection to Pueblo Bonito, one of the most prominent sites in Chaco Canyon. This collaboration between researchers, archaeologists, and the Picuris Pueblo community highlights the power of ancient DNA research to uncover critical historical truths.

Collaboration Between Researchers and the Picuris Pueblo

Eske Willerslev, Professor at the Globe Institute, highlighted the significance of the study as a model for future community-driven research. “This study shows the power of collaboration between indigenous communities and researchers, ensuring that archaeological context is preserved while advancing the field of ancient DNA,” he said.

The collaboration, involving the University of Copenhagen, Southern Methodist University (SMU) in Texas, and the Picuris Pueblo people, represents a rare and valuable partnership between DNA researchers and indigenous groups to explore and preserve ancestral histories.

Uncovering Ancient Connections through DNA

The DNA samples were meticulously extracted from tiny fragments of bone and teeth, each less than 1/20th of a teaspoon, allowing the team to generate genomes from 16 historical Picuris Pueblo individuals. The ancient DNA was compared to saliva samples from 13 living members of the Picuris Pueblo, as well as data from 300 American populations and over 5,500 individuals worldwide.

This research marks the first genetic confirmation of the long-held oral traditions within the Picuris Pueblo, strengthening their cultural connection to Chaco Canyon and the land. Through this collaboration, the Picuris Pueblo has gained a deeper understanding of their historical migration, dietary habits, lifestyle, and their relationship to sacred lands.

A Powerful Tool for Archaeology and Cultural Preservation

David Meltzer, Professor of Prehistoric Archaeology at SMU, emphasized the value of ancient DNA in advancing the field of archaeology. “Ancient DNA allows us to answer questions about ancient peoples that conventional archaeological methods simply cannot,” he said. “This research not only informs us about migration and lifestyle, but also about the evolution of diseases and contact between populations.”

For centuries, indigenous communities, including the Picuris Pueblo, have relied on oral traditions and ecological knowledge to maintain their cultural heritage. “This DNA research affirms our connection to sacred lands and waters, reinforcing our claims to these territories while preserving our culture,” said Craig Quanchello, Governor of the Picuris Pueblo.

The research not only bridges the gap between indigenous traditions and academic understanding but also aids in the preservation of cultural heritage that has long been marginalized due to colonization, land loss, and oppression.
