Traditional taxonomy (classification of organisms) was devised by carl linnaeus (1701: where each category is a taxon. From broadest to most specific: domain, kingdom, phylum, class, order, family, genus, species. Species: individuals in a species have many characteristics in common, and variation within the species is less than variations seen between species. In a living species, individuals must be able to breed and produce fertile offspring! Second name is species name, always lowercase, latin form. Species are grouped into genera (plural of genus: there are only 3 domains: bacteria, archaea, eukarya, there are 6 kingdoms, bacteria > eubacteria, archaea > archaebacteria, eukarya > plants, animals, fungi, protists. Another taxonomy organizes organisms based on genetic and evolutionary relationships.
