Resumen de Native American orign written in oldest genome
A 24,000-year-old boy from Siberia is helping redraw the Native American family tree. He is the oldest human to have his genome sequenced, and the results suggest that the first people to colonize the Americas were not simply east Asians. Instead, those early settlers had both western Eurasian and east Asian roots. The first Americans probably arrived from north-east Asia via a land bridge, around 15,000 years ago. Confusion arose because Native Americans have DNA that resembles that of people in east Asia, but no modern population exactly fits, says Eske Willerslev of the Natural History Museum of Denmark in Copenhagen. Plus Native Americans carry some DNA characteristic of Europeans.
