Ants Teaching Ants

A startling report by British researchers says that ants do not just operate by instinct, or by mimicking the behavior of older ants. Ants engage in active (albeit limited) teaching and learning. An ant that finds a food source will lead another ant to it, even though the "teacher" ant has to slow down, wait, or redirect the "learner" and thus delay its own meal. Not bad for a creature with a microscopic brain.
