Agriculture in Mesoamerica Richard S. MacNeish completed an extensive archaeological survey of Mesoamerica, during which he found the maize cobs in caves in Tehuacan, Puebla. It was originally suspected that these cobs date back to circa 5000 BC, however after radiocarbon dating it was determined that these finds date to 3500 BC.[1] The earliest dated maize cob was discovered in GuilÃ¡ Naquitz cave in Oaxaca and dates back to 4300 BC.[1] Maize arrived at this point through the catastrophic sexual transmutation of Teosinte,[2] the ancestor of maize. It became the single most important crop in all of Mesoamerica. Maize is storable for long periods of time, it can be ground into flour, and it easily turns into surplus for future use. Maize became vital to the survival of the people of Mesoamerica; this is reflected in their origin myths, artwork, and rituals. The Maize God is depicted throughout Mesoamerica in stone figurines, carvings on altars, and even on temples, further signifying the importance of maize to the Mesoamerican peoples.
