Dog from multiple grey wolf populations, with the dingo and New Guinea singing dog "breeds" having developed at a time when human populations were more isolated from each other. In the third edition of "Mammal Species of the World" published in 2005, the mammalogist listed under the wolf "Canis lupus" its wild subspecies, and proposed two additional subspecies: ""familiaris" Linneaus, 1758 [domestic dog]" and ""dingo" Meyer, 1793 [domestic dog]". Wozencraft included "hallstromi" - the New Guinea singing dog - as a taxonomic synonym for the dingo. Wozencraft referred to the mDNA study as one of the guides in forming his decision.
New Guinea singing dog gray wolf, the dog is not a descendant of the extant gray wolf but these are sister taxa which share a common ancestor from a ghost population of wolves that went extinct at the end of the Late Pleistocene, and the dog and the dingo are not separate species. The dingo and the basenji are basal members of the domestic dog clade. "The term basal taxon refers to a lineage that diverges early in the history of the group and lies on a branch that originates near the common ancestor of the group." Mitochondrial genome sequences indicates that the dingo
