The Harvard classification system is a method used to categorize and organize various types of organisms based on their evolutionary relationships. It employs a hierarchical structure, starting with broad categories like kingdom and narrowing down to more specific levels such as genus and species. This system helps scientists communicate about biodiversity and understand the connections between different life forms. Developed by Harvard University researchers, the classification system is widely used in fields like biology and ecology. It provides a standardized framework for naming and identifying organisms, ensuring consistency in scientific communication. This system is essential for studying ecosystems and conserving biodiversity.
