Apparently stupid animals often do remarkably intelligent things. Leaf-cutting ants, for example, “plant” leaves in underground farms, where they cultivate particular species of fungus to provision their colony. In so doing, the ants act as if they understand the environrnental conditions that optimize fungus growth. Entomologists studying this behavior, however, are rarely tempted to interpret the ants’ activities as conscious or goal-directed. Instead, they view them as relatively inflexible adaptations to particular selective pressures. Ants are good at cultivating fungus, but this is not taken as proof of any general skills in problem solving or learning.
