In the taxonomic treatment presented in the third (2005) edition of Mammal Species of the World, Canis lupus dingo is a taxonomic rank that includes both the dingo that is native to Australia and the New Guinea singing dog that is native to the New Guinea Highlands. It also includes some extinct dogs that were once found in coastal Papua New Guinea and the island of Java in the Indonesian Archipelago. In this treatment it is a subspecies of Canis lupus, the wolf (the domestic dog is treated as a different wolf subspecies), although other treatments consider the dog as a full species, with the dingo and its relatives either as a subspecies of the dog (as Canis familiaris dingo), a species in its own right (Canis dingo), or simply as an unnamed variant or genetic clade within the larger population of dogs (thus, Canis familiaris, not further differentiated). The genetic evidence indicates that the dingo clade originated from East Asian domestic dogs and was introduced through the Malay Archipelago into Australia, with a common ancestry between the Australian dingo and the New Guinea singing dog. The New Guinea singing dog is genetically closer to those dingoes that live in southeastern Australia than to those that live in the northwest. Taxonomic debate – the domestic dog, dingo, and New Guinea singing dog Nomenclature Zoological nomenclature is a system of naming animals. In 1758, the Swedish botanist and zoologist Carl Linnaeus published in his Systema Naturae the two-word naming of species (binomial nomenclature). Canis is the Latin word meaning "dog", and under this genus he listed the domestic dog, grey wolf and the golden jackal. He classified the domestic dog as Canis familiaris, and on the next page he classified the grey wolf as Canis lupus. Linnaeus considered the dog to be a separate species from the wolf because of its upturning tail (cauda recurvata), which is not found in any other canid. The International Commission on Zoological Nomenclature (ICZN) advises on the "correct use of the scientific names of animals". The ICZN has entered into its official list: Genus Canis in 1926, Canis familiaris as the type species for genus Canis in 1955, and Canis dingo in 1957. These names (such as Canis familiaris and Canis dingo) are then available for use as the correct names for the taxa in question by taxonomists who treat the entities concerned as distinct
