Initial inferences of the peopling of South America from molecular genetic data were dependent on a handful of classical genetic markers and/or markers with uniparental inheritance (mitochondrial and Y chromosome). These studies supported a clear picture for the peopling of South America from single North American gene pool, and this picture has remained robust by subsequent molecular studies. However, the characterization of hundreds of independently evolving loci, such as that provided by genome-wide marker studies, provided an unprecedented level of information for modeling and inferring the last great continental expansion of our species. In this presentation, we present the current state of genomics and its contribution inferring the number and path of the initial migrations into the Americas as well as the impact of subsequent population dynamics, including global admixture.
