Many unicellular pond critters, such as paramecium, exhibit
'animal' behavior in the form of obstacle avoidance, 
sexual reproduction, etc.  These are single-celled
animals, so obviously they're not big enough to have a brain,
even a very small one.  So what part of a pond critter
dictates its behavior?
