Archaic Foraging and Early Agriculture in Oaxaca, Mexico, Updated Edition

This volume reports on the excavation of Guila Naquitz cave in Oaxaca, a site that provides important evidence for the earliest plant domestication in the New World. Stratigraphic studies, examinations of artifactual and botanical remains, simulations, and an imaginative reconstruction make this a model project of processual archaeology.
