Explain the adaptive-inactivity theory of sleep.

Answer:

Responses may vary but should include some or all of the following information: Lack of inactivity that results from sleep may have helped animals to survive according to evolutionary perspectives. As a result, they weren't as exposed to danger, which increased their chances of surviving. The adaptive-inactivity theory of sleep posits that sleep is a product of continuous evolution. The theory states that humans need to sleep now because it was advantageous for them to have slept in the distant past. Humans slept at night because they were safer asleep in one spot during the night than if they had been hunting for food in the day, especially since their eyesight at night was so poor.
