Past and present genomes tell the story of Native American biological origins

The first human inhabitants of the Americas lived in a time thousands of years before the first written records, and the story of their transcontinental migration is the subject of ongoing debate and active research. A study by multi-institutional, international collaboration of researchers, published this week in Science presents strong evidence, gleaned from ancient and modern DNA samples, that the ancestry of all Native Americans can be traced back to a single migration event, with subsequent gene flow between some groups and populations that are currently located in East Asia and Australia. —> Read More
