Biological perspectives on the collapse of the pasion maya

Abstract

This paper reviews bioarchaeological research that aimed to test the biological correlates of ecological explanations for the Maya collapse using human skeletal remains from five sites in the Pasion region. Stable isotope ratios of bone collagen and alkaline earth ratios in bone minerals do not support the expectation of increased reliance on maize and declining meat consumption during the final years of Pasión occupation. Moreover, skeletal pathology does not illustrate any increment in anemia, infectious disease, or dental growth disruption that is predicted to have been a consequence of high population density and deteriorating nutrition. Instead, changes in the social distribution of foods during the Terminal Classic supports the mounting evidence that the Pasión collapse was fueled more by sociopolitical transformations than environmental ones.
