Document Summary
Tool use goes back way further (6-7 mya) its just that olduwan tools are the oldest we can identify. Tools: flakes (flakes chipped off of other rocks to make sharp edges), cores (what"s used to chip the flakes off of), hammer stone (used to strike, create the flakes) Mode 1 (no systematic shape, more random) Mode 2 (first associated w/ homo erectus, acheleun industry , systemic in their structure, they were trying to create the same thing over & over again) Mode 3 (creating chisels, long blades, using levallois technique . Tool makers seemed to be majorly right handed. Generalized (one tool used for many purposes) Expedient (curated = kept for long time/treasured/valued, olduwan tools were only made when needed then thrown away) Made with hard hammer percussion method (hammer stone was very hard) Later tool histories show that they used something more soft (gave them more control) Hard to say which was first australopithecine species to use it.
