What is taxonomy? The science of naming and classifying organisms. Who is the "Father" of Taxonomy? Carolus Linnaeus Binomial nomenclature Each species is assigned a unique two-part name. The first part is a noun that designates the genus and the second part is an adjective that modifies the noun called specific epithet. Modern hierarchy system of classification. Rules for scientific naming 1. Typically latinized 2. Two part name: Genus and species 3. Genus is capitalized and species ...
