We do not know what became of the Nean-derthals. Perhaps they were exterminated in warfare, although there is no evidence of this. Perhaps they were simply unable to compete for food and living space with the better-equipped Cro-Magnon type. Perhaps they interbred, although there are no clear traces of intermediate forms. Some have suggested that Cro-Magnon men brought with them some disease to which they themselves were resistant and the Neanderthals were not. In any case, soon after the appearance of Cro-Magnon man, there were no other hominids in Europe, and within the course of 10000 to 20000 years, this new variety of primate had spread the face of the planet.
