You got that right. There have already been a lot of suggestions as to why modern humans over ran the world when they did, but they are all questionable. There seems to have been an overall increase in innovation about that time, but if you ask several paleoanthropologists what it was you will probably get just as many answers. It could have been the development of advanced languages. That is one I kind of like, but just because I like it doesn't make it right. Obviously having advanced languages was necessary, but it may not have been the final driver. You will get a lot of argument about just how advanced the language used by the Neanderthals was.
