Susan Savage-Rumbaugh and the Amazing Bonobo Apes
This video is a little long (a whopping 18 minutes!), but I found it fascinating. Savage-Rumbaugh is a leading expert on bonobos, a Congolese ape that she has worked with for years. In this video, she demonstrates their understanding of the English language, plus their ability to use tools (they start fires with lighters and extinguish them with jugs of water), plus their capacity to, well, to play Pac Man.
