TEDxPeachtree focuses on ideas worth spreading in myAJC mentions this video. By the way, TEDxPeachtree returns this Friday, November 8th.

This features Frans de Waal showing videos demonstrating animals cooperating on tasks, something we think of as human behavior. One I really liked was chimpanzees give the researcher a prosocial (feed both) or antisocial (feed chooser) token and how often they picked the prosocial was measured. Retaliation by the non-choosing chimpanzee reduced how much the choosing one picked the prosocial option.
