Rohde - Bio Chap. A classification system based on collecting individuals into groups and groups into progressively more inclusive and broader groups is called a hierarchical scheme of classification. For example, humans have backbones like all other vertebrates, but they share fewer characteristics with fish and birds than with other mammals.
Taxonomy is the science of classifying organisms.
Carolus Linnaeus devised a taxonomic scheme that was both practical and adaptable to expanding information. Bacteria, with their variety of forms of genetic exchange, do not fit this definition neatly. Together, the 2 constitute the species name . The species name is always latinized and underlined or italicized. The genus designation is capitalized, but the specific epithet is not.
