Who developed the binomial nomenclature system?

The binomial nomenclature system was developed by Carolus Linnaeus, a Swedish botanist and zoologist, in the 18th century. This system provides a standardized method for naming organisms using two terms: the genus name, which is capitalized, and the species name, which is in lowercase. This method of naming is essential in biology and ecology as it eliminates confusion caused by local or common names, allowing scientists worldwide to universally identify species.

Linnaeus's approach was groundbreaking because it organized living organisms into hierarchical categories and introduced the idea of classification based on shared characteristics, which laid the groundwork for modern taxonomy. The simplicity and structure of binomial nomenclature continue to be widely used in biological sciences today, making the naming and classification of organisms clearer and more systematic.

While Mendel contributed significantly to genetics, Darwin is known for his theory of evolution and Wallace for his work in biogeography, neither developed a formal naming system for organisms like Linnaeus did. Thus, the correct choice is indeed Carolus Linnaeus.
