Ancient DNA from Siberian boy links Europe and America
Mal'ta boy burial: Ancient DNA from Siberian boy links Europe and America. Scientists have mapped the genome of a four-year-old boy who died in south-central Siberia 24,000 years ago. It is the oldest modern human genome sequenced to date, researchers report in the journal Nature. The results provide a window into the origins of Native Americans, whose ancestors crossed from Siberia into the New World during the last Ice Age.
