 | | Circadian rhythms are important in determining the sleeping and feeding patterns of all animals, including humans. | | | The circadian rhythm is neither fully dependent nor fully independent of external cues such as sunlight and temperature. | | | However it has been well established that a mechanism for adjustment also exists, as plants and animals will eventually adjust their internal clock to a new pattern (if it is sufficiently regular). |
