Relationships between the human migration and the cultural changes in ancient Andean society

This project examines the relationships between genetic composition and cultural changes in the Andean region through interdisciplinary investigation of the skeletal remains of various pre-Hispanic cultures. Looking at the coastal area, the genetic stock of the regional population was consistent with the stock of people of the equatorial coastal region during the Formative periods but, as time went on, people of the different stock increasingly arrived from the highland area. This influx accelerated during the Inca and colonial periods, nearly replacing the indigenous population of this area. On the other hand, pre-Hispanic to modern populations of the north coast are genetically similar to each other. Since the first millennium A.D. to today, the north coast region has maintained a relatively large population, retaining genetic diversity avoiding genetic drift. Our results provide new information about the patterns of genetic diversity in ancient Peruvian society, and its role in the cultural changes of the ancestral Andean society.
