- 1. Linnaean taxonomy, also known as binomial nomenclature, is a hierarchical system of classifying and naming organisms established by the Swedish botanist Carl Linnaeus. This system categorizes living organisms into a hierarchical structure consisting of Kingdom, Phylum, Class, Order, Family, Genus, and Species. Each organism is given a unique two-part scientific name, with the first part identifying the genus and the second part identifying the species. Linnaean taxonomy is widely used in the field of biology to organize and categorize the vast diversity of life on Earth.
