"waggle dance"*

Honeybees really are nature’s little treasures. They are a centimeter or so long, their brains are tiny, and a small set of simple rules can explain the sophisticated social behavior that produces the coordinated activity of a hive. They live by sets of instructions that are familiar to computer programmers as subroutines – do this until the stop code, then into the next subroutine, and so on.

These humble little bees have an innate ability to work out the location of a food source from its position in relation to the sun. They do this even on cloudy days by reading the pattern of the polarization of the light, and pass this information to other bees. In the dark of the hive, they transpose the location of a food source in the horizontal plane through the famous "waggle dance"* into communication in the vertical plane of the hive.

Honeybees can tell their sisters how far away the food is up to a distance of about 15 kilometers. For good measure, they can also allow for the fact that the sun moves relative to the hive by about 15 degrees an hour and correct for this when they pass on the information. In other words, they have their own built-in global positioning system and a language that enables them to refer to objects and events that are distant in space or time.
