DNA links modern pueblo dwellers to Chaco Canyon people

A thousand years ago, the people living in Chaco Canyon were building massive structures of intricate masonry and locations as far away as Mexico. Within a century, however, the area would be largely abandoned, with little indication that the same culture was re-established elsewhere. If the people of Chaco Canyon migrated elsewhere, it's unclear where they ended up.
Around the same time that construction expanded in Chaco Canyon, far smaller pueblos began appearing in the northern Rio Grande Valley hundreds of kilometers away. These have remained occupied to the present day in New Mexico; although their populations shrank dramatically after European contact, their relationship to the Chaco culture has remained ambiguous. Until now, that is. People from one of these communities, Picuris Pueblo, worked with ancient DNA specialists to show that they are the closest relatives of the Chaco people yet discovered, confirming aspects of the pueblo's oral traditions.
A pueblo-driven study
The list of authors of the new paper describing this genetic connection includes members of the Pueblo government, including its present governor. That's because the study was initiated by the members of the Pueblo, who worked with archeologists to get in contact with DNA specialists at the Center for GeoGenetics at the University of Copenhagen. In a press conference, members of the Pueblo said they'd been aware of the power of DNA studies via their use in criminal cases and ancestry services. The leaders of Picuris Pueblo felt that it could help them understand their origin and the nature of some of their oral history, which linked them to the wider Pueblo-building peoples.
