David Reich
David Emil Reich (nacido el 14 de julio de 1974) es un genetista estadounidense conocido por su investigación sobre la genética de poblaciones de humanos antiguos, incluidas sus migraciones y la mezcla de poblaciones, descubierta mediante el análisis de patrones de mutaciones en todo el genoma. Es profesor en el departamento de genética de la Escuela de Medicina de Harvard y asociado del Instituto Broad. Reich Recibió la Medalla Darwin-Wallace en 2019. proporcionado por Wikipedia

There are many unanswered questions about the population history of the Central and South Central Andes, particularly regarding the impact of large-scale societies, such as the Moche, Wari, Tiwanaku, and Inca. We assembled genome-wide data on 89 individuals dating from ~9000-500 years ago (BP), with a particular focus on the period of the rise and fall of state societies. Today’s genetic structure began to develop by 5800 BP, followed by bi-directional gene flow between the North and South Highlands, and between the Highlands and Coast. We detect minimal admixture among neighboring groups between ~2000-500 BP, although we do detect cosmopolitanism (people of diverse ancestries living side-by-side) in the heartlands of the Tiwanaku and Inca polities. We also reveal cases of long-range mobility connecting the Andes to Argentina, and the Northwest Andes to the Amazon Basin.
