2.4 Linnaean system of nomenclature INTRODUCTION KEY HIGHLIGHT ❖ The Linnaean system of nomenclature, ❖ Species Naming: A species' scientific name is developed by Carl Linnaeus, is a standardized composed of two parts: the genus and the specific method for naming living organisms. This system epithet. provides a universal language for scientists across ❖ Example: The scientific name of a human is the globe, helping to avoid confusion that may Homo sapiens, where "Homo" is the genus and arise from local or common names. "sapiens" is the specific epithet. Carl Linnaeus and His Contributions: ❖ Carl Linnaeus was a Swedish naturalist who initially studied medicine but developed a strong interest in plants. ❖ He traveled extensively across Europe, discovering and naming many new species of plants. ❖ In 1735, he published Systema Naturae, where he described and classified 7,700 plant species and over 4,000 animals. Binomial Nomenclature: Importance of a Universal Naming System: ❖ Linnaeus refined and popularized the binomial ❖ The use of Latin names avoids confusion caused system of naming organisms, which is still used by regional language differences. For instance, today. maize is known by various names in Ethiopia ❖ In this system, each organism is given a name (Bekolo in Amharic, Boqqollo in Afan Oromo), consisting of two parts: the genus name and the but its scientific name Zea mays is universally specific epithet. recognized. ❖ The genus name is always capitalized, while the ❖ The binomial system helps distinguish between specific epithet begins with a lowercase letter. species that may look similar but belong to Scientific names are italicized when printed and different genera or species. underlined when handwritten. SUMMARY The Linnaean system of nomenclature is vital for ensuring that organisms are named consistently and recognized globally, regardless of local languages or regional differences. This universal system allows scientists to communicate more effectively and avoid confusion, which is crucial in studying and understanding the diversity of life on Earth. Carl Linnaeus initially classified whales as fish, a mistake that was later corrected, demonstrating how scientific classification evolves over time.
