Divergent Evolution of the Zapotec and Mixtec Civilizations

A case study in the divergent evolution of Mexico’s Zapotec and Mixtec civilizations, this collection has become a basic resource in the literature of Mesoamerican prehistory and has been widely cited by scholars working on divergent evolution in other parts of the world. Originally published by Academic Press in 1983, a new introduction by the editors updates the volume in terms of discoveries made during the subsequent two decades.
