We would have also noticed differences in the eyes and nose. The upper jaw did not stick out, the front teeth were smaller than the Neanderthals' and the lower jaw had changed so that Cro-Magnons had full chins. The face was short and wide and the ridges over the brows had almost disappeared. The skull had changed shape so that it was longer and narrower than the Neanderthal skull, with a straight forehead and a higher, more rounded braincase. We would have seen that the head was also more like ours. The Cro-Magnons were lighter boned, had long, slender arms and legs, and they had large hands with short fingers that allowed precision grips. If we had been alive then, we would have seen that we look more like the Cro-Magnons than the Neanderthals. After the first modern humans (Cro-Magnons) emerged in Africa about 100 000 – 120 000 years ago, they migrated northward, spreading rapidly over Europe and Asia.
