A " groundbreaking " desoxyribonucleic acid depth psychology of a little Pueblo clan in New Mexico supports what their oral custom has long described — that they ’re related to to ancestral people who hold out on their ground , as well as to autochthonal people who be a few hundreds international mile away at Chaco Canyon .
The new inquiry is the first desoxyribonucleic acid evidence that the federally recognized tribe , known as Picuris Pueblo , has transmissible ties to Chacoans buried at Chaco Culture National Historical Park , aUNESCO World Heritage Siteand a shoes many Southwest Indigenous peoples weigh consecrated .
The Pueblo Bonito site at Chaco Canyon. Ancient DNA from several people buried here centuries ago confirms that they’re related to the Picuris Pueblo people in New Mexico.
" We ’ve always said we have this deep connection to Chaco Canyon , " study co - authorCraig Quanchello , the police lieutenant governor of Picuris Pueblo , enjoin at a news league on April 29 . " It not only run through our veins , but now through skill . "
Pueblo peoples
Picuris Pueblo , where the kindred know , is in the Sangre De Cristo Mountains of northern New Mexico , about 60 miles ( 100 kilometer ) north of Santa Fe . It was historically one of the most populated pueblo , with over3,000 tribal members around 1600 . But in the decade followingEuropean contact in 1591 , last , disease and religious persecutionreduced the Picuris universe significantly . Now , tribal membership is around300 individuals .

To learn more about their genetic heritage , Picuris Pueblo leadership reach researchers in 2020 .
In that sketch , whose results were published Wednesday ( April 30 ) in the journalNature , investigator analyzed ancient DNA from 16 individuals buried in Picuris Pueblo dated to between 500 and 700 years ago , as well as 13 genome from currently enrolled members of Picuris Pueblo . They compared these genome to 590 ancient and modern genome from the Americas and Siberia , since the first Americans travel across a land bridge circuit connecting Siberia with Alaska during the last deoxyephedrine ageat least 23,000 years ago .
Their results unwrap that the modern Picuris are related to those who lived in the pueblo C ago . The psychoanalysis also indicated that the Picuris are related toAnzick-1 , a kid who lived 13,000 years ago in what is now Montana and was part of an Indigenous American group called the Clovis . But " part of their [ the Picuris ] origin is actually honest-to-goodness than the pedigree that we find in the Clovis individual , " study leading authorThomaz Pinotti , a geogeneticist at the University of Copenhagen , said at the news conference .

" We were pretty distorted up about using these data point , because we knew how controversial they were , " discipline co - authorMike Adler , an associate professor of anthropology at Southern Methodist University , said at the newsworthiness conference . " When we brought this up to the tribal council , it was a very simple answer : ' That ’s not your call . That ’s our call . You should use these data , because it ’s an avenue to meliorate our understanding of our own past . ' "
