Bonobos Documented for First Time Using Ancient Pre-Agricultural Tools, Breaking Bones, and Using Spears as Attack Weapons

An interesting study on great apes behavior, with Bonobos ( one of the two Pan species) making tools and weapons. This has a lot of implications for human evolution especially early hominds. The rudimentary tools would be complex to identify, as would be the wooden spears. The study can be found here.

 

HAIFA University, ISRAEL—The University of Haifa announced that bonobos have been observed making and using tools and spears for the first time. Chimpanzees in nature have been seen making tools to obtain food such as tubers and termites, breaking open nuts with hammers and anvils, and making spears from branches for hunting. Itai Roffman of the university’s Institute of Evolution provided bonobos in a zoo setting and in a sanctuary setting with food that had been buried, hidden, and concealed in various locations. He also provided them with raw materials for toolmaking such as green branches and deer antlers. Both groups of bonobos were able to perform the food extraction tasks, but the sanctuary bonobos were much more successful. “The bonobos essentially showed that once they have the motivation to do so, they have analogous capabilities to those of archaic pre-humans, which is logical as chimpanzees and bonobos are our genetic sister species,” said Roffman in a press release. In addition, the dominant female in the zoo group crafted spears from the sticks, and she used the weapons to threaten Roffman. “To the zoo bonobos, I was a trespasser who was violating their privacy and stalking them,” he added.
