A collaborative project in Mesoamerica and Southwestern North America draws on interdisciplinary approaches, surveys, and the study of concrete evidence of changes in maize, to challenge the long-held view that the shift to agriculture from hunting was uniform across regions. Instead, they argue that this transition happened in two phases, beginning with central areas low-productivity launches, followed by satellite areas' faster production rates.
