Abstract: Fifty seven percent of the 138 cultivated plant species present in Amazonia at contact probably originated in the Amazon Basin and another 27% originated in lowland northern South America. The relationship between probable indigenous human population density and resultant agricultural intensification and crop diversity is used to propose the existence of a mosaic of crop genetic resource concentrations in Amazonia at contact, including two centers of diversity, four outlying minor centers, and five regions of diversity. This methodology is extrapolated to present a synthesis of South American crop genetic biogeography at contact.
