Classification involves grouping things together based on similarities. There are two main types of classification: taxonomy, which classifies living things; and systems created by Aristotle and Carolus Linnaeus. Linnaeus developed binomial nomenclature, using a two-word Latin naming system with the genus as the first word and specific epithet as the second to precisely classify organisms. This scientific naming convention using capitalized genus and lowercase specific epithet is still used today.
