Biological Nomenclature is the system of naming organisms, which is based on the binomial system developed by Carl Linnaeus. The term is composed of two parts: the GENUS and the species. The GENUS is the first part of the name and is usually a single word, such as Homo for humans. The species is the second part of the name and is usually a combination of two words, such as sapiens for humans. Together, these two words form the scientific name for an organism.
