The use of stone tools is something that separated our ancestors from the chimps. Until now that is!
Kanzi is a chimp that’s been trained for years to make stone tools. Check out this amazing video of him creating a stone tool to solve a puzzle. Keep an eye out for some bipedalism in this video too (and a bit of banana eating, because no primate video would be complete without that)!
As impressive as that was Kanzi still isn’t as good as our ancestors were at making stone tools; despite years of training.
Even our early Australopith ancestors – who were very chimp like – were better than he is. This is because Kanzi has a relatively short thumb and immobile wrist (both adaptations for knuckle walking). This prevents him from using the same precision grip as our ancestors (and us), making it difficult for him to control his blows and produce a high quality tool.
Luckily for us it would seem the chimp revolution is still a little way off. But when they do take over, don’t say you didn’t see it coming.
