Why sleep?
All living organisms show a regular, daily period of reduced activity. But to what extent could this be sleep, and what is it for? Whatever the functions of sleep are, they probably shift in emphasis across the animal kingdom. There are fundamental differences between rodents and us. On the other hand, even human sleep has some similarities with that of the bee.
