What is the binomial naming system?

• A. Three word naming system (Genus species)
• B. One word naming system
• C. Two word naming system (Genus species)
• D. Four word naming system

Answer: (C)

Two words form the name of a species: the genus and the species epithet. This two-word format, Genus species, provides a unique, internationally understood label. The genus is capitalized and the species epithet is lowercase, and the full name is typically written in italics. Developed by Linnaeus, this system standardizes names across languages and regions, preventing confusion from common names. For example, Homo sapiens or Canis lupus illustrate how related species share a genus, while each species has its own specific epithet. Subspecies can add a third term (Canis lupus familiaris), but the core binomial name remains two words. The other options describe naming with more or fewer words, which aren’t how binomial nomenclature works.
