Corn is the descendant of a wild grass called teosinte. Native Americans used special growing techniques to change teosinte into larger ears of corn. In 1492, Christopher Columbus brought corn back to Spain. Eventually Europeans and the rest of the world began growing and eating corn.
Christopher Columbus and other explorers from Spain brought corn and many other new foods back to Europe.
