How did Carl Linnaeus group organisms?

Carl Linnaeus grouped organisms by the binominal system, a system he invented for separating animals and plants into a genus name and a species name. Linnaeus is called "the Father of Taxonomy" for his work in species classification.

Linnaeus developed his system of taxonomy during the 18th century. It would soon be known as the Linnaean system and classified nature within an identification hierarchy, beginning with Kingdoms.

Kingdoms were divided into Classes, which, in turn, were divided into Orders, Genera (genus) and Species.

Linnaeus' two most famous books, Species plantarum and Systema naturae, are still in use today by scientists for deciding the names of plants and animals.
