Homo erectus lived around 1.8mya - apx. 200,000 years ago in Africa, Asia, and Europe. Homo erectus traits include a larger brain (~900cc), a long, low skull, thick cranial bones, a sagittal keel, less prognathism, smaller teeth, a receding chin, and modern body size and proportions. Homo erectus had the capability to create tools, identified under the Acheulean tool industry that occurred around 1.5 mya. This includes symmetrical, bifacial flaking. These tools provide evidence of coordination and cooperation. Furthermore, evidence of cooking food due to smaller tooth/jaw size, larger brain, larger body, and smaller gut are associated with this species.
