Why was corn important to the growth of settled villages in Mesoamerica?

Corn was fundamental to the development of settled villages in Mesoamerica because it provided a reliable and abundant source of food energy, eventually accounting for approximately 90 percent of the calories in the Mesoamerican diet.1

The transition to settled life was closely linked to the domestication and improvement of corn alongside other crops like beans and squash. As these plants became more productive, they allowed populations to move away from temporary, seasonal hunting camps toward semipermanent villages. This increased food security enabled groups to establish year-round settlements, which were further supported by the development of tools like metates and manos for grinding corn into meal or dough.1

By the Early Formative period, the stability provided by agriculture allowed for the growth of larger territorial units and complex societies, such as the Olmec, which were organized around ceremonial centers. Ultimately, the ability to produce and store a food surplus was essential for supporting the labor force and the complex urban centers of later civilizations.2
