From the Paper:

"Whether asleep or awake, busy with daily activities such as work, play, or eating, humans show a very complex, yet very base, form of evolutionary progress. This evolution has allowed human beings to adapt to the natural 24-hour day/night routine that is dictated by the sun's rising and setting, and also dictates when certain activities must be done. This paper will look at the biological rationale for such activity, a process known as circadian rhythm. First, circadian rhythm will be defined and explained. Then, the brain and the environment's affectations upon circadian rhythms will be discussed. Third, the reasons why human beings must sleep will be studied. Finally, the essay will investigate the factors that dictate the time invested in sleep and awake states. Circadian rhythm is what has allowed human beings to adapt to the 24-hour cycle that makes up day and night in this world."
