The activity patterns of animals represent fundamental characteristics in all species.  Most species tend to be active during a certain part of the diel cycle (e.g., day or night), and are behaviorally, anatomically and physiologically adapted to that phase.  These rhythms have evolved in response to the temporal structure of the environment, allowing animals to adapt to their specific temporal niche, and anticipate the appropriate time for a certain activity and behavior.
