In 1735, the first edition of Carl Linnaeus' "Systema Naturae" was published; this work included information on both insects and intestinal worms. However, the tenth edition is considered the true starting point for the modern classification scheme for living things today. Linnaeus' universal system of classification made a system based on binomial nomenclature, but included higher levels of classification than simply the genus and species names. "Systema Naturae" was an investigation into the biodiversity on Earth. However, because it was based only on very few characters, the system developed by Linnaeus was an artificial one. The book also included descriptions of the organisms named inside of it.
