The results presented here are part of the Project of Investigation, Conservation, and Enhancement of the Huaca Pucllana directed by Dra. Isabel Flores Espinoza, with the guidance of the National Institute of Culture and the City of Miraflores. The remains of two individuals were found during the 2007 and 2009 excavation seasons in Huaca Pucllana, in part of the construction fill used as a base for the fifth platform built during The Middle Horizon 1B. In this context we observe two forms of burial. One was on a bed of canes with offerings while the second was only wrapped in a textile bundle. The analysis of the excavation, of the bones and the textiles permits the suggestion that both individuals were sacrificed at the same time as part of rituals related to the modification of the architectonical structure.

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.
