"OR! As I believe, modern humans could have developed numerous times/places from a common source."

But would that explain how Mungo Man has mtDNA that matches no one else? Could it be these "species" developed independently without that common ancestor? Could it also be that there was parallel development in other parts of the world, albeit independent development?
