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 Europeans brought technologies, ideas, plants, and animals that were new to America and would transform peoples’ lives: guns, iron tools, and weapons; Christianity and Roman law; sugarcane and wheat; horses and cattle. They also carried diseases against which the Indian peoples had no defenses.

Detailed explanation-3: -Europeans brought horses, cattle, sheep, goats, and pigs, among others. These animals changed agricultural practices and transportation. Horses had a huge effect on the indigenous American economies and culture. Buffalo hunting became far more efficient when done on horseback.

Detailed explanation-4: -Columbus’ second voyage was the starting point for the re-introduction, bringing Iberian horses to modern-day Mexico. Some of the Iberian horses escaped European control and became wild horses, relatives of the mustangs in the Western United States today.

Detailed explanation-5: -In the late 1400s, Spanish conquistadors brought European horses to North America, back to where they evolved long ago. At this time, North America was widely covered with open grasslands, serving as a great habitat for these horses. These horses quickly adapted to their former range and spread across the nation.
