Adaptive response to the realities of life and death

Reference no: EM13497607

My textbook suggests that the amount of sleep that an animal engages in may partially be due to evolutionary factors. For example, animals that are at a high risk of being hunted by predators tend to sleep less, an adaptive response to the realities of life and death. For this Discussion Post, discuss why you think humans sleep as much as they do. Do you believe that the amount we sleep has evolved over time or is there another explanation?
