It shows how encaptured chimps can be taught to care for their predator’s cubs. A chimp’s natural environment can also make him do just the opposite. In 1986 researchers described how a group of wild chimpanzees deliberately managed to drag a leopard’s cub away from its mother and then kill it.... Read more »
