What Makes Us Human?

Some of the most basic ques­tions about human exis­tence (how did we devel­op lan­guage? why do we love music and art but kill in war? how did we devel­op cer­tain eat­ing habits? etc.) come back to a more sin­gu­lar ques­tion: how are we dif­fer­ent from chim­panzees? This ques­tion is slow­ly get­ting answered by some of today’s lead­ing pri­ma­tol­o­gists and evo­lu­tion­ary biol­o­gists, includ­ing Robert Sapol­sky, Daniel Lieber­man, Richard Wrang­ham, Jane Goodall, Steven Pinker, all fea­tured above.
