Book excerpt: La Consentida explores Early Formative period transitions in residential mobility, subsistence, and social organization at the site of La Consentida in coastal Oaxaca, Mexico. Examining how this site transformed during one of the most fundamental moments of socioeconomic change in the ancient Americas, the book provides a new way of thinking about the social dynamics of Mesoamerican communities of the period. Guy David Hepp summarizes the results of several seasons of fieldwork and laboratory analysis under the aegis of the La Consentida Archaeological Project, drawing on various forms of evidence—ground stone tools, earthen architecture, faunal remains, human dental pathologies, isotopic indicators, ceramics, and more— to reveal how transitions in settlement, subsistence, and social organization at La Consentida were intimately linked. While Mesoamerica is too diverse for research at a single site to lay to rest ongoing debates about the Early Formative period, evidence from La Consentida should inform those debates because of the site’s unique ecological setting, its relative lack of disturbance by later occupations, and because it represents the only well-documented Early Formative period village in a 300-mile stretch of Mexico’s Pacific coast. One of the only studies to closely document multiple lines of evidence of the transition toward a sedentary, agricultural society at an individual settlement in Mesoamerica, La Consentida is a key resource for understanding the transition to settled life and social complexity in Mesoamerican societies.
