The First Peopling of South America: New Evidence from Y-Chromosome Haplogroup Q

A recent study published in PLOS examines Y-chromosome data from more than 400 Native Americans to shed further light on the peopling of the Americas. This study focuses on Y-chromosome data from Native American individuals belonging to haplogroup Q -- the only Y-chromosome haplogroup observed in Central and South Native Americans. The study reveals two main founding lineages, one of which is observed in Far East Asia and a subclade of the other in southern Siberia. Results support a Y-chromosome based conclusion of a Siberian origin of founding populations in the Americas, and indicates two main lineages descending down into the Americas from Beringia.
