Question

Which biological organisms that travelled from the Afro-Eurasia to the Americas had the largest long-term effect? Explain why.​

Answer 1

The Americas, was, without a doubt, more affected than Afro-Eurasia by the Columbian Exchange.

In the Americas, the Columbian Exchange caused, indirectly, the death of up to 90% of the Native American population, due to the spread of diseases from Afro-Eurasia for which the Native Americans had no antibodies.

It also caused the development of new states, that were dominated by Europeans and their descendats: the Spanish viceroyalties, Portugese Brazil, the English, French, and Dutch Colonies in North America and the Caribbean.
