Canidae - Classification and Relationship

Classification and Relationship

The subdivision of Canidae into "foxes" and "true dogs" may not be in accordance with the actual relations; also the taxonomic classification of several canines is disputed. Recent DNA analysis shows that Canini (dogs) and Vulpini (foxes) are valid clades (see phylogeny below). Molecular data implies a North American origin of living Canidae and an African origin of wolf-like canines (Canis, Cuon, and Lycaon).

Currently, the domestic dog is listed as a subspecies of Canis lupus, C. l. familiaris, and the dingo (also considered a domestic dog) as C. l. dingo, provisionally a separate subspecies from C. l. familiaris; the red wolf, eastern Canadian wolf, and Indian wolf are recognized as subspecies. Many sources list the domestic dog as Canis familiaris, but others, including the Smithsonian Institution and the American Society of Mammalogists, more precisely list it as a subspecies of C. l. familiaris; the red wolf, eastern Canadian wolf, and Indian wolf may or may not be separate species; in the past, the dingo has been variously classified as Canis dingo, Canis familiaris dingo and Canis lupus familiaris dingo.
