Document Summary
Functions of stone tools determined by: context (e. g. found with animal bones at kill site, use wear (damage on the edge of the tool from use, experiment (flakes are particularly good for cutting through hide - very sharp) Use-wear on 9 unmodified flakes from kobi fora: Core-tools: likely used for heavy-duty butchering and marrow bone breakage. Who made these earliest tools: homo habilis (2. 3 - 1. 6 mya) One locality at olduvai - h. habilis found with oldowan tools. Must have produced many of the tools: robust australopithecines - around at the same time. Earliest definite bone tools are found in south africa and at olduvai gorge, after 2 mya. Simply chunks of bone with polish, possibly used to dig in the ground for plant foods. No good evidence for use of fire at this time. East africa - many sites with fairly tight clusters of bones and stone tools.
