Integrating archaeological, palaeoecological, and chronological data, we argue for the coexistence of a diversified and a more complex food production systems in the Cerrado biome. These findings demonstrated that eastern South America populations practiced maize-based polyculture, reshaping current models of cultural and environmental dynamics in the Cerrado biome.",
