Document Summary
Species a population of organisms capable of interbreeding and producing fertile offspring. Each species should be genetically distinct from the others. It is difficult to have only one definition of the word species because organisms are dynamic and evolving. Hybridization 0 reproduction involving more than one species. Taxonomy the science that identifies, names, and classifies new species. Binomial nomenclature species are assigned a latinized two-part name, a species name or binomial. The first part of their name identifies a genus, which is a group with similar characteristics. When writing the name, the first letter of the generic is always capitalized, and never capitalized on the specific. The whole name is italicized, and the specific is never present without the generic, but the generic can be shortened or abbreviated. Linnaeus created a taxonomy hierarchy which comprises a series of formal categories: domain, kingdom, phylum, class, order, family, genus, species, and subspecies. A taxon is the organisms in any of these categories.
