The term for the first scientific method of classifying living organisms is taxonomy. Taxonomy involves categorizing organisms into hierarchical groups based on shared characteristics, either morphological, genetic, or behavioral. The system was pioneered by Carolus Linnaeus, who developed a binomial nomenclature system for naming species. This classification not only aids in organizing biological knowledge but also facilitates communication among scientists globally. Understanding taxonomy is essential for studying biodiversity, evolution, and ecological relationships within the natural world.
