Skull Comparison (Click on the image above to rotate the object)
Compare the 3D scans of actual human, Neanderthal and chimpanzee skulls. Some Neanderthal skulls—and brains—were actually larger than those of modern humans. Compared with humans, Neanderthals also had protruding faces, prominent brows, large noses, and receding chins. A chimpanzee's skull is much smaller than a human's, and its brain is about one-third the size of a human brain. In addition, a chimpanzee's face protrudes far forward of its brain case, and it has large, tusk-like canine teeth.
