Why are babies cute? Why is cake sweet? Philosopher Dan Dennett has answers you wouldn’t expect, as he shares evolution’s counterintuitive reasoning on cute, sweet and sexy things (plus a new theory from Matthew Hurley on why jokes are funny). (Recorded at TED U 2009, February 2009, in Long Beach, California. Duration: 07:45.)
