At the Gombe Stream we have seen chimpanzees nse objects for many different
rposes. They use grasses and sticks to catch and eat insects: and 直 the materal is
ot suitable、they cbange it in some way.They use leaves to take up water一and ret
they chew the leayes so they wi hold more water. One chimpanzee used leaves to
ean out the last remans of brain from a baboom's skull*。 We have seen them use
tandfuls of leaves to rub Girt from their bodies, or to dry up wounds.
So far、no chimpanzee has managed to use one tool to make another. One
chimpanzee was tested again and again。She was taught to use a sharp blade to break
ittle bits o圧 a piece of wood: these bits could then pick food out of a narrow pipe.
She coutd do thie when she could break o全bits with her teeth. She was shown
the use cf the blade many times, but she never even attemped to use it or the
problem. Howwewer, many other chimpanzees must be tested一we cannot be sure that
