If so, there may have been originally more than one ancient domestication event for dogs as there was for domestic pigs. One theory is that domestication occurred during one of the five cold Heinrich events that occurred after the arrival of humans in West Europe 37 000, 29 000, 23 000, 16 500 and 12 000 YBP.

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
