Artificial Organisms That Sleep

Artificial Organisms That Sleep
Populations of artificial organisms live in an environment in which light is cyclically present (day) or absent (night). Since being active during night is non-adaptive (activity consumes energy which is not compensated by the food found at night) the organisms evolve a sleep/wake behavioral pattern of being active during daytime and sleeping during nighttime. When the population moves to a different environment that contains "caves", they have to get out of a cave although the dark conditions of the cave may tend to induce sleep. We study various solutions to these problems: evolving a light sensor, evolving a biological clock, evolving both a light sensor and a biological clock. The best solution appears to be evolving a light sensor that modulates a biological clock, a solution which may also be appropriate to solve other problems such as adapting to seasonal changes in daytime length.
