Genetic diversity and population structure

Resumo

Highlights•Genome-wide analysis of 49 Central and South Americans up to ∼11,000 years old•Two previously unknown genetic exchanges between North and South America•Distinct link between a Clovis culture-associated genome and the oldest South Americans•Continent-wide replacement of Clovis-associated ancestry beginning at least 9,000 years agoSummaryWe report genome-wide ancient DNA from 49 individuals forming four parallel time transects in Belize, Brazil, the Central Andes, and the Southern Cone, each dating to at least ∼9,000 years ago. The common ancestral population radiated rapidly from just one of the two early branches that contributed to Native Americans today. We document two previously unappreciated streams of gene flow between North and South America. One affected the Central Andes by ∼4,200 years ago, while the other explains an affinity between the oldest North American genome associated with the Clovis culture and the oldest Central and South Americans from Chile, Brazil, and Belize. However, this was not the primary source for later South Americans, as the other ancient individuals derive from lineages without specific affinity to the Clovis-associated genome, suggesting a population replacement that began at least 9,000 years ago and was followed by substantial population continuity in multiple regions.Graphical abstract
