ECON 212 Chapter Notes - Chapter 7: Taphonomy, Homo Erectus, Brain Size
Document Summary
7: the origins of culture and the emergence of homo. Many anthropologists surmise that members of the early homo species, rather than the australopithecines, made those tools found in various sites in east africa. Early homo had a brain capacity almost one-third larger than that of the australopithecines. Earliest identifiable stone tools come from various sites in east africa and date from ab. 2. 5 mil. years ago: oldest tools were discovered at gona, ethiopia. Percussion flaking: a toolmaking technique in which one stone is struck with another to remove a flake. Both sharp-edged flakes and sharp-edged cores (the pieces of stone left after flakes are removed) were probably used as tools. Includes core tools, sharp-edged flakes, choppers (cores that have been partially flaked and have a side that might have been used for chopping), scrapers (flaking along one side and a flat edge) Unifacial tool: a tool worked or flaked on one side only.
