Biological Clock
The Biological Clock is an endogenous mechanism responsible for regulating various physiological and behavioural rhythms in mammals. Mammals are warm-blooded vertebrates that belong to the class of the Mammalia. They can be characterized as eukaryotes observed through their endocrine and phenological features. Also, mammals give birth to live young, who are then fed milk produced by the maternal mammary glands. This class includes species like primates, carnivores, rodents and ungulates. Rhythmic changes occurring due to the biological clock happen in all mammals. These changes are genetically programmed and can be observed yearly, monthly and daily. Daily cyclical rhythms are also called Circadian Rhythms (from the Latin circa dies, “about a day”). Period lengths less than 24 hours are called ultradian. (Biological Clock)
