Linnaeus created a system of biological classification that organized plants and animals into a hierarchy with 7 levels based on their physical appearance and evidence. He named and categorized over 4,000 species using binomial nomenclature with a capitalized genus name followed by a species name in italics, establishing the foundation of modern taxonomy.
