UC Berkeley post-doctoral researcher, Thomas Morgan, demonstrates stone-knapping, how our hominin ancestors in the Stone Age made sharp tools out of rocks, for butchering their game. His research findings suggest that the practice of teaching  this skill to younger generations helped drive the development of communication and language.
