eli5: Why do African animals not get scared being next to each other, while in other continents they do?

Question

I know at least in North America, you don’t usually see congregations of large animals, but in all documentaries about Africa, you see lions, hippos, gazelles, zebras, etc all together

Answer 1

Well a great deal of animals went extinct on other continents (including North America) whenever mankind showed up. Africa is the only continent where animal evolved next to humans (remember humans came from Africa). My point is that it could just be a symptom of having more species of animals around to commingle. No more North American lions, camels, wooly mammoths, etc.
