History of Corn

Researchers believe that corn was developed by natives living in Central America at least 7,000 years ago.

Corn was developed by the Olmec, and Mayans, and was heavily traded in North, Central, and South America.

Corn is a domesticated grass. Corn is not found in the wild, but was domesticated and bred by natives, and was developed from a wild grass called teosinte.

There was no corn in Europe prior to Christopher Columbus voyages to the new world. While in the West Indies, Columbus traded with the natives and brought corn back to Europe

Native Americans in North America introduced corn to early settlers, and saved them from starvation by trading with them, and taught them how to plant, and cultivate corn using fish for fertilizer.

Indians taught the early settlers how to make various corn dishes including corn bread, corn pudding, corn soup, and fried corn cakes.
