Carbonized remains of Canavalia beans were recovered from archaeological deposits excavated at Real Alto (OGCh-12), southwestern Ecuador. The identification, context and dating of the earliest beans from Real Alto demonstrate their use from the beginning of Valdivia (about 3300 B.C.) and the Early Formative in coastal Ecuador.
