How did agriculture affect the development of civilizations in Mesoamerica and the Andean region?
When early humans began farming, they were able to produce enough food that they no longer had to migrate to their food source. This meant they could build permanent structures, and develop villages, towns, and eventually even cities. Closely connected to the rise of settled societies was an increase in population.
