The historic region of Mesoamerica comprises the modern day countries of northern Costa Rica, Nicaragua, Honduras, El Salvador, Guatemala, Belize, and central to southern Mexico. For thousands of years, this area was populated by groups such as the Olmec, Zapotec, Maya, Toltec, and Aztec peoples.
As a cultural area, Mesoamerica is defined by a mosaic of cultural traits developed and shared by its indigenous cultures. Beginning as early as 7000 BCE, the domestication of cacao, maize, beans, tomato, avocado, vanilla, squash and chili, as well as the turkey and dog, resulted in a transition from paleo-Indian hunter-gatherer tribal groupings to the organization of sedentary agricultural villages.
