Alfred coined the term Columbian exchange in 1972. The Columbian exchange started to connect the New and Old Worlds with the transmission of ideas, plants, animals, and diseases. Two worlds that had grown apart with very different organisms started to become homogeneous (Crosby, 1972).
The Spanish also brought African slaves to work on sugar plantations. New foods for both Europe and the Americas was a major part of the Columbian Exchange. The Americas provided such new foods as corn, the potato, the tomato, peppers, pumpkins, squash, pineapples, cacao beans (for chocolate) and the sweet potato. Also, such animals as turkeys, provided a new food source for Europeans.
