Since then, Zhoukoudian has attracted worldwide attention. Why did this discovery stir the world? Because this skull provides valuable information for studying human evolution. He not only has human nature, but also retains the characteristics of ancient apes; He can walk upright, his limbs, trunk and skull are very human, and his brain is bigger than that of ancient apes and modern great apes. The head is steamed bread-shaped, the brow ridge is thick, protruding above the orbit, the forehead is flat, and the skull wall is thicker than that of modern people, similar to that of ancient apes. Later, some human fossils were discovered here. The richness of fossils and the comprehensiveness of the parts represented are unprecedented in the world. Later, Neanderthals were discovered here, and the unearthed fossils and relics proved that they were much later than Beijingers. However, this precious cultural site was not well protected before liberation. 194 1 On the eve of the Pacific War, a batch of fossils, including the skull of Peking Union Medical College, were packed and transported away by Americans and disappeared mysteriously soon.
