I don't think it is at all controversial (I'll try and find some material on this later). It's quite certain that a very small number of humans (perhaps less than 500... likely less than 250) left Africa and ended up populating the rest of the available land mass (everyone of "non-African" descent). That means that "all of the modern human genes" pretty much stayed in Africa with most of the modern human populations that never left.
