“Are humans the Bi-Polar Ape, caught between love and war forever?

Featured on The Guardian, Steven Pinker, Richard Wrangham and Frans de Waal discuss the evolutionary evidence and debate whether human nature is essentially violent like our chimpanzee cousins or essentially peaceful like our equally related bonobo ancestors.” -YT
