Why colonization occurred is because:
1. FOOD: Europe developed cuisine which allowed them to anatomically develop faster.
2. Africa had their feudal period late than that of Europe.
3. A feudal period not only makes a better warrior, but it better develops the peace ethic that blacks currently lack.
When Europeans came to Africa on a quest for food, they had suffered and evolved through a harsh feudal period. Africa was just starting on theirs. But because of their diets, they were small pygmies in stature. This is true for most of the native cultures at this time. Conquistadors only conquered pygmies.
Africa did nothing wrong except for not develop cuisine.
