Harvard and U.of C, Santa Cruz researchers, and researchers from Argentina, Australia, Bolivia, Chile, Germany, Peru, the United Kingdom and the United States, undertook a genome study of 89 Ancient Andeans who lived between 500-9000 years ago, including the Moche, Nasca, Wari, Tiwanaku and Inca. They found that groups in the Andean highlands became genetically distinct from those along the Pacific Coast. North and South groups differentiated from each other 5,800 years ago.
They found genetic mixing between the Andes, south Peru, Argentina, and the Amazon. This demonstrates large migrations. Now they need to find out more about those migrations. There was genetic continuity among large scale Andean populations like the Moche Wari, and Nasca, so invading military forces did not alter the genetics of the population.
The research is published in the Journal Cell
