Step-by-step explanation:
The most accurate statement regarding animals and the Columbian Exchange is that there were fewer animals capable of being domesticated in the Americas than in Europe, Asia, and Africa.
Before the encounter between Europe and the Americas, the Americas did not have animals such as horses, donkeys, sheep, chickens, and cattle. This lack of large domesticated animals in the Americas impacted the development of agriculture and transportation.
On the other hand, European animals such as pigs, sheep, chickens, and cattle were introduced to the Americas and thrived there, contributing to the expansion of populations and the availability of animal protein in diets.
