Binomial nomenclature is a system used to name living organisms. It was developed by the Swedish botanist Carl Linnaeus in the 18th century. Each species is given a two-part name: the first part identifies the genus, and the second part specifies the species. For example, in the name Homo sapiens, Homo is the genus, and sapiens is the species. This naming system helps scientists communicate clearly about different organisms, avoiding confusion caused by common names. The names are usually in Latin or Greek, providing a universal language for biologists worldwide. This consistency is essential for research and classification in biology.
