VARIATION IN DIETARY HISTORIES AMONG THE IMMIGRANTS OF MACHU PICCHU: CARBON AND NITROGEN ISOTOPE EVIDENCE

This study estimates dietary composition during infancy and childhood among 71 adults interred at the site of Machu Picchu, a royal Inca estate in the southern highlands of Peru. Recent research suggests that the majority of individuals were members of the cosmopolitian yana and aclla servant classe...
