摘要: We report genome-wide ancient DNA from 49 individuals forming four parallel time transects in Belize, Brazil, the Central Andes, and Southern Cone, each dating to at least ∼9,000 years ago. The common ancestral population radiated rapidly just one of two early branches that contributed Native Americans today. document previously unappreciated streams gene flow between North South America. One affected Andes by ∼4,200 ago, while other explains an affinity oldest American genome associated with Clovis culture Chile, Belize. However, this was not primary source for later Americans, as derive lineages without specific Clovis-associated genome, suggesting a replacement began at least 9,000 ago followed substantial continuity multiple regions.
