Was first brought to the Americas from Europe?

Many crops, animals, and cultural practices were first brought to the Americas from Europe following the Age of Exploration, particularly during the Columbian Exchange in the 15th and 16th centuries. Notably, European settlers introduced wheat, barley, and domesticated animals like horses and cattle. Additionally, various diseases, such as smallpox, were also brought over, which had devastating effects on Indigenous populations. This exchange significantly altered the agricultural and cultural landscapes of the Americas.
