Maize, squash and beans: domestication in the Americas

c. 8000-2000 BCE · Mesoamerica and the Andes

Indigenous peoples domesticated maize from wild teosinte in southern Mexico, along with squash, beans and chili, while potatoes, quinoa and other crops were domesticated in the Andes. Dry caves in Oaxaca preserve some of the earliest evidence of plant domestication in the Americas.
