The genome sequence of a 24,000-year-old Siberian boy has provided a key piece of the puzzle in the quest for Native American origins. The ancient Siberian demonstrates genomic signatures that are basal to present-day western Eurasians and close to modern Native Americans.
This surprising finding has great consequences for our understanding of how and from where ancestral Native Americans descended, and also of the genetic landscape of Eurasia 24,000 years ago. The breakthrough is reported in Nature by an international team of scientists, led by the Centre for GeoGenetics at the Natural History Museum of Denmark (University of Copenhagen).
