The authors issue a corrective statement declaring that at the time of their article publication, they were unaware of a manuscript arriving at broadly similar conclusions based on allotype analysis by Williams et al., which appeared in the American Journal of Physical Anthropology.
At the time of publication of this Letter, the authors were unaware of a manuscript arriving at broadly similar conclusions based on allotype analysis by Williams et al., which appeared in the American Journal of Physical Anthropology. Their original article showed that Native Americans descend from at least three streams of Asian gene flow, and most descend entirely from a single ancestral population that we call ‘First American’. The article also showed that the initial peopling followed a southward expansion facilitated by the coast, with sequential population splits and little gene flow after divergence, especially in South America. A major exception is in Chibchan speakers on both sides of the Panama isthmus, who have ancestry from both North and South America. (Published Abstract Provided)
