Understanding Taxonomy and Classification in Biology

Scientists use classification to group organisms logically, making it easier to study life's diversity. Taxonomy assigns universally accepted names to organisms using binomial nomenclature. Carolus Linnaeus developed this system, organizing organisms into species, genus, family, order, class, phylum
