What is Columbian Exchange and give an example?

Answer 1

The Columbian Exchange refers to the widespread transfer of plants, animals, culture, human populations, technology, and diseases between the Americas and the Old World (Europe, Asia, and Africa) following Christopher Columbus's voyages in the late 15th century. An example of this exchange is the introduction of crops such as potatoes and maize to Europe, which significantly impacted European agriculture and cuisine, while European livestock like cattle and sheep were brought to the Americas, transforming indigenous farming practices.
