Carl Linnaeus was considered the "Father of Taxonomy" because he developed a way to name and organize species that we still use today. Two of his most important contributions to taxonomy were: (1)hierarchical classification system and (2)system of binomial nomenclature (two part naming method). The Linnaean system is based on a simple hierarchical structure in which organisms are sorted using the nomenclature of Kingdom, Phylum, Class, Order, Family, Genus and Species. Names are based on universal language which is Latin. The scientific name gives the genus and species name of an organism. The entire name is written in italics or is underlined. Example is our own species, Homo sapiens. It can be written as Homo sapiens or Homo sapiens.
