HUMAN LARKS AND OWLS. “Human subjects can be divided into different chronotypes ranging from very early active “larks” to very late active individuals “owls”. These studies have revealed two unexpected, if not shocking aspects of circadian rhythmicity. First, extreme larks and owls hardly overlap with regard to their sleep-wake cycles. Second, the chronotype changes significantly during the lifetime of an individual.”
