Scientists discover evidence of early human innovation, pushing back evolutionary timeline

(University of Utah) An international collaboration has discovered that early humans in eastern Africa had--by about 320,000 years ago--begun trading with distant groups, using color pigments and manufacturing more sophisticated tools than those of the Early Stone Age. These behavioral innovations may represent a response to the rapid environmental and climactic changes occurring at the time.
