Abstract (AI)
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 ∼9,000-500 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 5,800 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 ∼2,000-500 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 highlight cases of long-range mobility connecting the Andes to Argentina and the Northwest Andes to the Amazon Basin. VIDEO ABSTRACT.
Key Findings
1
Cosmopolitan communities containing people of diverse ancestries existed in the heartlands of the Tiwanaku and Inca polities.
2
Despite major state societies, neighboring Andean populations showed minimal genetic admixture from approximately 2,000–500 years BP.
3
Genome-wide data from 89 individuals dated approximately 9,000–500 years BP reconstruct deep population history in the Central and South Central Andes.
4
Long-distance mobility connected the Andes with Argentina and linked the Northwest Andes with the Amazon Basin.
5
Modern genetic structure began developing by approximately 5,800 BP, with subsequent bidirectional gene flow between northern and southern highlands and between highlands and coast.
