How did Neanderthals and cro-mangos differ from either people's?

Neanderthals and Cro-Magnons were early human ancestors who lived alongside modern humans but eventually went extinct. Neanderthals had a distinctive physical appearance with a robust body and large brow ridges, while Cro-Magnons were anatomically similar to modern humans. Both groups had their own unique tool-making techniques and cultural practices, but Cro-Magnons were more advanced in their art and symbolic behavior.
