Chimpanzees living in the West African savannah have been observed fashioning deadly spears from sticks and using the tools to hunt small mammals — the first routine production of deadly weapons ever observed in animals other than humans.And there was this interesting tidbit:
... The new observations are "stunning," said Craig Stanford, a primatologist and professor of anthropology at the University of Southern California. "Really fashioning a weapon to get food — I'd say that's a first for any nonhuman animal."
The landmark observation also supports the long-debated proposition that females — the main makers and users of spears among the Senegalese chimps — tend to be the innovators and creative problem solvers in primate culture.
