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: -However, it was only with the first voyage of the Italian explorer Christopher Columbus and his crew to the Americas in 1492 that the Columbian exchange began, resulting in major transformations in the cultures and livelihoods of the peoples in both hemispheres.

Detailed explanation-3: -The Columbian exchange is named after Christopher Columbus because his discovery of the New World began the ongoing exchange of objects, organisms, and ideas between the Old World and the New World.

Detailed explanation-4: -When Christopher Columbus and his crew arrived in the New World, two biologically distinct worlds were brought into contact. The animal, plant, and bacterial life of these two worlds began to mix in a process called the Columbian Exchange.

Detailed explanation-5: -Five hundred years before Columbus, a daring band of Vikings led by Leif Eriksson set foot in North America and established a settlement. And long before that, some scholars say, the Americas seem to have been visited by seafaring travelers from China, and possibly by visitors from Africa and even Ice Age Europe.
