Investigator Stephen Black writes:
From the November 2006 issue of Smithsonian Magazine in which the psychologist Sue Savage-Rumbaugh describes the abilities of one of her language-learning bonobos, Kanzi:
“Once, Savage-Rumbaugh says, on an outing in a forest by the Georgia State University laboratory where he was raised, Kanzi touched the symbols for ‘marshmallow’ and ‘fire.’ Given matches and marshmallows, Kanzi snapped twigs for a fire, lit them with the matches and toasted the marshmallows on a stick.”
Not so impressive. He didn’t know a single campfire song.
