plants, possibly tubers, formed the foundation of the diet in both sites during the Formative period (~3000-200 BC). Maize was a marginal food (<12% of calories) at least until 800 BC (29% of calories). The Maritime Foundations hypothesis does not completely account for these findings. Our results suggest the predominance of crop-focused agriculture during the evaluated period.
