Lecture Topic: Homo Ergaster and Homo Erectus Pliocene-Pleistocene boundary at 1.8 mya Increase in body size, changes in post-crania suggesting in modern bipedalism Traditionally these humans were called homo erectus Modern Consensus breaks H. ergaster = Africa and H. erectus = Asia Major adaptive shift in hominin evolution Who were the first universally accepted Homo? First migration out of Africa Eugene Dubois – sailed to Dutch East Indies, interested in paleontology digs at solo River, near Trinil and found Trinil Calvaria (1891) found Femur bone, thicker, definitely bipedal, called it Pithecanthropus erectus An upright human-like ape Why is 1.7 mya a significant point in human evolution? Dissent whether they represent same species Dubois find no more bones and returns to Netherlands in 1895 Von Koenigswald found 3 more skulls Did limb bone and skull represent same species? Weidenreich by 1937 – 40 individuals, made casts and drawings called it Sinanthropus pekinensis In 1939, Von Koenigswald and Weidenreich compared their fossils in China and conclude Sinanthropus and pithecanthropus into Homo erectus Skulls found in China and Indonesia poorly dated, 1.8 mya? No attention to stratigraphy, poor recording Asian Homo erectus date Zhonkoudien, China 1984 by West Turkana, Walker and Richard Leakey, 1.6 mya Significant because it shows us H. Erectus was tall Long and robust lower limbs, large body size 5.6' when he died at age 12, might have reached 6' as an adult Homo erectus/ergaster Who was the Nariokotome boy (The strapping youth) During the lecture, take notes here.
