Theoretically, that evidence best supports the hypothesis that people in the Southern Highlands domesticated this important crop plant.
Methodologically, sedimentary pollen and other microfossil sequences can make valuable contributions to reconstructing the geography of early maize cultivation, but we must acknowledge the limits to precision that bioturbation in coastal lagoons imposes on the dating of such records. But much disagreement remains concerning the mechanism, location, and timing of the domestication process and, therefore, its relationship to Mesoamerican social and environmental processes, such as the inception of sedentism and deforestation.
1) that demonstrates maize cultivation there by 5,000 years ago, and this finding refines the understanding of the geography of early maize cultivation and its relationship to social and environmental change.
