In 1927, Davidson Black named a new species Sinanthropus erectus (literally "Northern upright man"), based on a tooth discovered at Zhoukoudian near Bejing (Peking), China. The later discovery of 14 calvaria (skull caps), limb bones, and many more teeth strengthened his claim. One of these calvaria became better known as "Peking Man." As more fossils of erectus-like hominins were discovered, paleoanthropologists began to recognize the similarities between Pithecanthropus/Sinanthropus and specimens that had been assigned to the genus Homo. Eventually, both Pithecanthropus and Sinanthropus fossils were subsumed into the species Homo erectus. …show more content…
Compared with australopithecines and earlier Homo, Homo erectus had smaller teeth, a shorter face, and a humanlike projecting nose. The numerous skulls that have been discovered show a significant increase in brain size compared with earlier hominins. On average, the cranial capacity of Homo erectus was about 900 cc, although its range (750 cc–1,250 cc) overlaps that of modern humans (1,000 cc–2,000
