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
Origin of the domestic dog some regional breeds and regional wolves. In 2011, a study found that there had been dog-wolf hybridization and not an independent domestication. East Asia: In 2002, a study of maternal mDNA indicated that the dog diverged from its ancestor in East Asia because there were more dog mDNA haplotypes found there than in other parts of the world, but this was rebutted because village dogs in Africa also show a similar haplotype diversity. In 2015, a whole genome analysis of modern dog and wolf sequences concluded that based on the genetic diversity of today's East Asian dogs, the dog had
