Ancient Wari Empire likely did not cause large shifts in population genetic diversity
The imperial dominance of the ancient Wari Empire at the Huaca Pucllana site in Lima, Peru, was likely not achieved through population replacement, according to a study published June 1, 2016 in the open-access journal PLOS ONE by Guido Valverde from the University of Adelaide, Australia, and colleagues.

To investigate whether Wari dominance in the Peruvian Central Coast was based on population replacement or cultural diffusion, the authors of the present study sequenced the complete mitochondrial genomes of 34 individuals from the Huaca Pucllana archaeological site in Lima, Peru, who lived before, during, and after the Wari Empire, and assessed how the population's genetic diversity changed over time.

Guido Valverde adds: "The Huaca Pucllana archaeological site in Peru's Central Coast represents a unique transect of three successive cultures -- Lima, Wari and Ychsma. The site provides the exceptional opportunity to study a 1000 years of pre-Inca history, including the impact of the Wari imperialist expansion on Peru's Central Coast cities."
