Have you gotten your DNA done?

Centaur, are you sure you mean the tribes weren't there or that colonial powers pushed tribes together into the geographic spaces they wanted them in?

Rwanda is a good example. There were tribes before colonization, I'm pretty sure. The problems may have resulted from external powers trying to make one country out of distinct tribes.

ETA: I stand corrected on Rwanda, at least according to what wikipedia has to say. The two two major "tribes" don't seem distinct at all as far as genetics and language. Interesting.
