Origin of the domestic dog or the result of natural introgression as the dog expanded across Eurasia. In 2018, a study found a small amount of dog ancestry in 62% of Eurasian wolf specimens looked at, that hybridization had occurred across a wide number of timescales and not just recently, however in contrast there was almost no admixture detected in the North American specimens. There was introgression of the male dog into the wolf, but also one hybrid detected which was the result of a male wolf crossed with a female dog. Wolves have maintained their phenotype differences from the dog, which indicates low-frequency hybridization.
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
