New Astonishing Culinary Behavior Found In Chimps
January 1, 2010
The extraordinary thing about their behavior is the fact that they are actively chopping up the food into small portions to pass out among themselves, cutting up those portions into bite size pieces for them to eat more easily.
It is the first time this kind of behavior has been seen in chimps, or animals of any kind, and shows a marked difference in the way their society appears to be evolving.
The chimps were studied by two members of the Leverhulme Centre for Human Evolutionary Studies, University of Cambridge; Professor William McGrew and PhD student Kathelijne Koops.
“Chimpanzees across Africa vary greatly in the types of tools they use to obtain food,” Koops explained.
“Some groups use stones as hammers and anvils to crack open nuts, whereas others use twigs to fish for termites. These chimpanzees were found to deliberately modify termite fishing probes by creating a brush-end, before using them to fish for termites.
“And it’s the first time wild chimpanzees have been found to use two distinct types of percussive technology, i.e. movable cleavers versus a non-movable anvil, to achieve the same goal.”
