Document Summary
Homo: genus to which modern humans and their ancestors belong. Foramen magnum: opening in the base of the skill through which the spinal cord passes en route to the brain. Homo habilis: early species belonging to our genus, homo, with cranial capacities averaging about 630-640 cc, about 50 percent of the brain capacity of modern humans. Homo erectus: the first hominin species to be widely distributed in the old world. The earliest finds are possibly 1. 8 million years old. The brain (895-1040 cc) was larger than that found in any of the australopithecus or h. habilis but smaller than the average brain of a modern human. Sahelanthropus tchadensis: probable primitive hominin, known from fossils dated 7 to 6 million years ago from a site in chad. Orrorin tugenensis: an apparently bipedal primate dating to between 5. 8 million and 6 million years, making it possibly the earliest known hominin.
