Notice that when you see images of juxtaposed human and Neanderthal skulls, the Neanderthal skull is most often shown looking down at his feet so as to make the Neanderthal appear as if he had a flat face like one of ours. Note however that if you rotate the Neanderthal skull upward sufficiently to make the line of his teeth horizontal as is the line of the human teeth, the Neanderthal is seen to be prognathic, i.e. to have a snout just like a dog or a cat or any other land mammal native to Earth.
