Who developed the two-part scientific name system for living organisms?

• A. Charles Darwin
• B. Carolus Linnaeus
• C. Louis Pasteur
• D. Gregor Mendel

Answer: (B)

Binomial nomenclature, the two-part naming system for living organisms, was created by Carolus Linnaeus in the 18th century to standardize how species are named. It assigns each species a Latinized name with two parts: the genus and the species epithet. The genus is capitalized and the epithet is lowercase, and the full name is usually italicized. This structure provides a unique, universally understood label for every species, so scientists anywhere can be sure they’re talking about the same organism despite language differences or local common names. Linnaeus’s framework, popularized in Systema Naturae, organized life into a hierarchical system and established conventions still used today. Other famous scientists—Darwin, Pasteur, Mendel—made foundational contributions in evolution, microbiology, and genetics, but the specific two-part naming system is Linnaeus’s contribution.
