“Imperialism and the Family Business: Population Structure and Political Change on the Central Coast of Peru”

The Late Intermediate Period (A.D. 1000 – 1450) on the coast of Peru was the scene for a complex array of social, political, and economic interactions. During this period, the Chancay culture of the Central Coast flourished in the face of northern pressure from the encroaching Chimú Empire and the consolidation of the seafaring Chincha polity to the south. Jahnke examines osteological and archaeological data to reconstruct Pre-colonial population structure on the Central Coast of Peru and discusses the challenges for conducting bioarchaeological research amidst ongoing archaeological site destruction.

Presented by the Mütter Museum of The College of Physicians of Philadelphia.
