USA HISTORY

Detailed explanation-1: -Christopher Columbus introduced horses, sugar plants, and disease to the New World, while facilitating the introduction of New World commodities like sugar, tobacco, chocolate, and potatoes to the Old World. The process by which commodities, people, and diseases crossed the Atlantic is known as the Columbian Exchange.

Detailed explanation-2: -The exchange introduced a wide range of new calorically rich staple crops to the Old World-namely potatoes, sweet potatoes, maize, and cassava. The primary benefit of the New World staples was that they could be grown in Old World climates that were unsuitable for the cultivation of Old World staples.

Detailed explanation-3: -In 1492, Columbus brought the Eastern and Western Hemispheres back together. The resulting swap of Old and New World germs, animals, plants, peoples, and cultures has been called the “Columbian Exchange.” Humans from Asia probably first entered the Western Hemisphere between 20, 000 and 30, 000 years ago.

Detailed explanation-4: -The most devastating component of the Columbian exchange was the transfer of Old World diseases to the Americas. Among the lethal germs were smallpox, measles, mumps, whooping cough, chickenpox, typhus, and influenza.

Detailed explanation-5: -The Columbian Exchange was more evenhanded when it came to crops. The Americas’ farmers’ gifts to other continents included staples such as corn (maize), potatoes, cassava, and sweet potatoes, together with secondary food crops such as tomatoes, peanuts, pumpkins, squashes, pineapples, and chili peppers.
