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 a divergence between Southeast Asian and Western Eurasian dogs 17,500-23,900 YBP and this indicates a single dog domestication event occurring between 20,000-40,000 YBP. The study did not support a dual domestication event found by an earlier study. A 2018 study of mDNA sequences shows that the pre-Neolithic dogs of Europe all fell under haplogroup C. The Neolithic and Post-Neolithic dogs from Southeastern Europe that are associated with farmers fell under haplogroup D. In Western and Northern Europe, haplogroup D became diluted into the native dog population. This implies that haplogroup D arrived in Europe 9,000 years ago from the Near
