Evolution of what? Evolution in general? Or evolution of a specific organism? You want us to explain how it works or something else? Please make it more clear

Sorry. I should have been more specific. I need to know about the Human Evolution theories (Out of Africa, Multi Regional ...) and what evidance there is for each if these.

well, the evidence that supports it is where the fossils of increasing age are located. There is also some project,I forgot the name, that tested everyone in the world for their y chromosome differences. Evidently a tribe in africa has the least mutations.

Dave is right. The oldest "human", that was actually an Australopitecus aferensis(named Lucy by archeologists) was found in Africa, the valley of the Olduway river

I have pretty good idea of the evidence...
But i need to know what the theories are? e.g. What is the multi-regional theory? What is the Eve Hypothesis?
