Whole genome sequencing indicates the dog to be a genetically divergent subspecies of the grey wolf, the dog is not a descendant of the extant grey 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 falls within the domestic dog clade, and that the New Guinea singing dog is genetically closer to those dingoes that live in southeastern Australia than to those that live in the northwest. The dingo and New Guinea singing dog lineage can be traced back through the Malay Archipelago to Asia. Gene flow from the genetically divergent Tibetan wolf forms 2% of the dingo's genome, which likely represents ancient admixture in eastern Eurasia.
