Ancient baby’s DNA reveals completely unknown branch of Native American family tree (page 2)

Credit: Eric S. Carlson in collaboration with Ben PotterWhen scientists recently sequenced the genome of a six-week-old infant girl who lived 11,500 years ago at an Alaskan site now called Upward Sun River (USR), they expected that her DNA would match the genetic profile of other northern Native American people. Instead, the genome of the infant — named Xach'itee'aanenh T'eede Gaay, meaning "Sunrise Girl-Child" and called USR1 by scientists — matched no other known ancient population. "It was very surprising to find that USR1 belonged to a Native American population that was actually distinct from the two main Native American branches to which all Native American genomes sequenced to date belong to," J. Víctor Moreno-Mayar of the University of Copenhagen Center for GeoGenetics told Seeker. "This means that this population was living up there, isolated from other Native American groups, for a considerably long time," he added. Moreno-Mayar and his colleagues' findings, published in the jour
