Perhaps no other food has been more closely identified with the Americas than corn. Both the Mayan and the Olmec civilizations that date back to 2000-1500 BC in what is now Mexico and Central America (commonly called Mesoamerica) had not only adopted maize as a staple food in the diet but had also developed a reverence for maize that was expressed in everyday rituals, religious ceremonies, and in the arts. The first domestication of maize in Mesoamerica actually dates back even further, to 9000-8000 BC. Corn was equally valued by Native American tribes living in North America, although tribal wisdom about corn was largely ignored by European colonists in the 15th and 16th centuries AD.
