Video of Bonobo Learning to Make Stone Tools

January 26, 2021

I really don’t know if it’s a good idea to teach apes to make edged weapons – they’re physically much more powerful than we are as it is without giving them the knowledge to make stone blades. This is a video I found on the Cornell Arts and Sciences Channel on YouTube. It’s of a bonobo, Kanzi, being encouraged to make flint blades by one of the scientists, Dr. Sue Savage-Rumbaugh. The blurb for the video on its YouTube page runs

In the 1990s, paleo-anthropologists Nick Toth and Kathy Schick taught Kanzi the bonobo to produce stone tools using techniques that were adopted by our early ancestors. In this 7-min excerpt, primatologist Sue Savage-Rumbaugh is using language to encourage Kanzi to produce a certain number of tools—seizing the opportunity to consolidate his counting capacities. Near the end of the excerpt, Kanzi is trying to vocalize some numbers. (copyright Sue Savage-Rumbaugh).

Savage-Rumbaugh lines all nine of the bonobo’s flakes up in a row, and then tries to get him to count them. She tries and fails to get Kanzi to say the numbers, but all the animal can do is screech. However, he points and taps the flakes that correspond to that number. It also looks like they’ve devised a means for the creature to communicate in English using a computer. The video shows a computer screen with tiny thumbnail pictures, and at one point a synthesised voice can be heard saying ‘rock’, ‘knife’ and other words. It looks to me – and I might be wrong – that the computer is touch sensitive and says the name of whichever object the bonobo touches, thus allowing it to communicate vocally in English with the experimenters.

Kanzi is clearly a very intelligent creature. There’s another video about him on YouTube, which calls him an ‘Ape of Genius’, so he’s obviously a bit brighter than the hacks writing for the Scum. Primatologists are interested in finding out just how intelligent our nearest ape relatives – chimps and gorillas – really are. There was considerable interest in Koko the gorilla, who was taught sign language. I’ve heard it said that at hear peak she had a vocabulary of 900+ words. Kanzi is just one of a number of bonobos, whom the researchers tried to teach to make stone tools. I think the aim of these experiments was to see if they could make the type of stone tools crafted and used by Homo Habilis, one of the very early hominid ancestors. From what I’ve read, the tools they produced were inferior to those made by Habilis. I suppose we shouldn’t be disappointed, though, and expect too much. It’s perhaps enough that Kanzi and his friends understand what’s being said to them, and that they’re able to do it and communicate back.
