Origin of the domestic dog haplotype designated as S805 (28,000 YBP) from the Yana River was one mutation away from another haplotype S902 (8,000 YBP) that represents Clade A of the modern wolf and domestic dog lineages. Closely related to this haplotype was one that was found in the recently-extinct Japanese wolf. Several ancient haplotypes were oriented around S805, including "Canis c.f. variabilis" (360,000 YBP), Belgium (36,000 YBP – the "Goyet dog"), Belgium (30,000 YBP), and Konsteki, Russia (22,000 YBP). Given the position of the S805 haplotype on the phylogenetic tree, it may potentially represent a direct link from the progenitor (including "Canis c.f. variabilis")
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
