[T]he Iberian conquest of the Azores, Madeiras and Canaries [w]as a pilot program for the reshaping of European colonies in the Americas, Africa, Australia, and Oceania. In all these places, the newcomers would conquer the human populations and Europeanize entire ecosystems. They dared this because they had seen from the Iberian experience in the Canaries that European crops and herds would thrive in all but the most hostile, unfamiliar environments, and that the fiercest indigenes could be beaten despite their superior numbers and home-ground advantage. As a result, tens of millions of natives around the world would die.
