Adaptive shifts with the origins of homo: greater consumption of animal tissues, not just meat - bone marrow, brain tissue, organs, evidence, stone tools, cut-marked bones, dental reduction, chewing muscle reduction (1) reflects increase in dietary quality. Stone tools: previous species had rough tools, but homo really used them more and better, earliest stone tools date to 3. 3 ma, stone tools rare before ca. 2. 5 ma, after which they become much more abundant: stone tools cultures have their own classification system, beginning with the.
