mean by the phrase, “global biological homogeneity?”

-The Columbian Exchange refers to the exchange of diseases, ideas, food. crops, and populations between the New World and the Old World following the voyage to the Americas by Christo pher Columbus in 1492.

-The Columbian Exchange brought horses, cattle, sheep, goats, pigs, and a collection of other useful species to the Americas. Corn (maize), potatoes, cassava, and sweet potatoes were also involved.

-When the Europeans arrived, carrying germs which thrived in dense, semi-urban populations, the indigenous people of the Americas were effectively doomed. They had never experienced smallpox, measles or flu before, and the viruses tore through the continent, killing an estimated 90% of Native Americans.
