Origin of the domestic dog to the domestic dog and modern wolf lineages. The gray wolf is thought to be ancestral to the domestic dog, however its relationship to "C. variabilis", and the genetic contribution of "C. variabilis" to the dog, is the subject of debate. The Zhokhov Island (8,700 YBP) and Aachim (1,700 YBP) canid haplotypes fell within the domestic dog clade, cluster with S805, and also share their haplotypes with – or are one mutation away from – the Tibetan wolf ("C. l. chanco") and the recently-extinct Japanese wolf ("C. l. hodophilax"). This may indicate that these canids retained the genetic signature of
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
