We are grateful to the members of Patagonian Native communities whom we consulted in the course of our research, in particular the Selk’nam, Yagán (Yámana), and the Mapuche-Tehuelche. We thank the Museo del Fin del Mundo, the Centro Austral de Investigaciones Científicas, the Universidad Nacional del Sur, and the Universidad de Magallanes for allowing us to access their collections. We thank Jakob Sedig, Mark Lipson, Matthew Mah, Iosif Lazaridis, and Iñigo Olalde for critical comments and helpful discussions. We thank Miguel Vilar for logistic support and Ricardo A. Verdugo for sharing modern Patagonian genotype data. N.N. is supported by a NIGMS (GM007753) fellowship. R.N. was supported by a National Geographic Society grant in the pilot program “Ancient DNA: Peopling of the Americas, 2018” and by CONICET (PIP 2015-11220150100953CO, PUE 2016 IDACOR, and BecExt 2017). J.M.B.M. was supported by ANPCyT (PICT 2015-1405). Archaeological research in Argentina was funded by grants to M.S. (CONICET PIP 0422/10 and 6199 and ANPCyT 05-38096) and to F.S. (CON-ICET PIP 0302). D.R. was supported by National Institutes of Health grant GM100233, by an Allen Discovery Center grant, and by grant 61220 from the John Templeton Foundation; D.R. is also an investigator of the Howard Hughes Medical Institute.

N2 - Archaeological research documents major technological shifts among people who have lived in the southern tip of South America (South Patagonia) during the last thirteen millennia, including the development of marine-based economies and changes in tools and raw materials. It has been proposed that movements of people spreading culture and technology propelled some of these shifts, but these hypotheses have not been tested with ancient DNA. Here we report genome-wide data from 20 ancient individuals, and co-analyze it with previously reported data. We reveal that immigration does not explain the appearance of marine adaptations in South Patagonia. We describe partial genetic continuity since ~6600 BP and two later gene flows correlated with technological changes: one between 4700–2000 BP that affected primarily marine-based groups, and a later one impacting all <2000 BP groups. From ~2200–1200 BP, mixture among neighbors resulted in a cline correlated to geographic ordering along the coast.
