The scientific name of the wolf is Canis lupus. The name indicates the wolf's

• A. Family and order
• B. Genus and species
• C. Species and subspecies
• D. Order and family

Answer: (B)

Binomial nomenclature uses two parts to name a species: the first part is the genus, the second part is the species. In Canis lupus, Canis is the genus and lupus is the species, so this name identifies the wolf at both the genus and species level. Higher levels like family or order aren’t shown in the two-part name, and adding a third term would indicate a subspecies (for example, Canis lupus familiaris is a subspecies of Canis lupus). The genus groups related animals, while the species name distinguishes this wolf from other species within the same genus.
