Well-tooled apes
The fascinating article “Aping the Stone Age” (SN: 11/21/09, p. 24) led me to wonder whether researchers who work with chimps or other higher apes have ever introduced them to the modern tools used by humans, such as saws, axes, hammers or pliers. If so, it would be interesting to know whether the apes could grasp the tools’ purposes, employ them productively and/or demonstrate their utility to ape kin.
