How are organisms named & classified: taxonomy branch of biology that"s concerned with naming & classifying organisms, modern taxonomy established by carolus linnaeus. Introduced two-part scientific name to all organisms: two-part scientific name of an organism is formed from genus & species. Genus group that includes number of very closely related species. Species within a genus includes populations of organisms that can potentially interbreed under normal conditions. Scientific names are always underlined or italicized: first letter of genus name always capitalized, first letter of species name always lowercase. Species name always paired with its genus name: linnaean classification system includes 8 major taxonomic categories, each category including all categories beneath it: Domain kingdom phylum class order . Family genus species: the more categories 2 organisms share, the closer their evolutionary relationship, today, process of classification focuses on reconstructing phylogeny - evolutionary history, systematics - science of reconstructing phylogeny.
