Detailed explanation-1: -Inactivity theory is based on the concept of evolutionary pressure where creatures inactive at night were less likely to die from the predation of injury in the dark, thus creating an evolutionary and reproductive benefit to being inactive at night.

Detailed explanation-2: -The adaptive theory states that animals sleep to avoid danger [12, 25]. For example, animals that are active during the day are vulnerable to predators at night, and therefore sleep to avoid being hunted and eaten.

Detailed explanation-3: -One evolutionary theory of sleep holds that sleep is essential for restoration of resources that are expended during the demands of day-to-day life. A second theory proposes that our sleep patterns evolved as an adaptive response to predatory risks, which increase in darkness.

Detailed explanation-4: -In lieu of an abstract, here is a brief excerpt of the content: THE EVOLUTIONARY THEORY OF SLEEP AND WAKEFULNESS NATHANIEL KLEITMAN* Which came first-the hen or the egg?
