The Columbian Exchange: Biological Transfer
The Columbian Exchange was the massive biological transfer between the Old World (Europe, Africa, Asia) and the New World (Americas) triggered by Columbus 1492 voyages, as taught in Pengi Social Studies Grade 7, Chapter 10: The Early Modern World. The Americas gave corn and potatoes to boost populations worldwide, while Europeans brought horses and diseases like smallpox to the Americas, killing up to 90% of Native American populations in some areas and causing the collapse of entire civilizations.
Key Concepts
The contact between the Old World (Europe/Africa/Asia) and the New World (Americas) triggered the Columbian Exchange —the global transfer of foods, plants, and animals. The Americas gave the world Corn and Potatoes , nutrient rich crops that boosted populations in Europe and China.
In return, Europeans brought Horses , cattle, and pigs to the Americas, transforming Native American lifestyles. However, they also brought invisible killers: diseases like Smallpox and measles. Native Americans had no natural immunity, and millions died (up to 90% of the population in some areas), causing the collapse of civilizations like the Aztec and Inca.
