Studies of the peopling Americas have focused on timing and number initial migrations. Less attention has been paid to subsequent spread people within Americas. We sequenced 15 ancient human genomes spanning from Alaska Patagonia; six are ≥10,000 years old (up ~18× coverage). All most closely related Native Americans, including those an Ancient Beringian individual two morphologically distinct "Paleoamericans." found evidence rapid dispersal early diversification that included previously unknown groups as moved south. This resulted in multiple independent, geographically uneven migrations, one provides clues a Late Pleistocene Australasian genetic signal, well later Mesoamerican-related expansion. These led complex dynamic population histories North South America.
