Previous genetic studies of dog lineages have concluded that domestication occurred in Southern China around 16,500 years ago, but the earliest archaeological evidence of domesticated canines is found in Europe and Siberia.
For the history of the dog, see Dog, Origin of the domestic dog. The origin of the domestic dog (Canis lupus familiaris or Canis familiaris) is not clear. Whole genome sequencing indicates that the dog, the gray wolf and the extinct Taymyr wolf diverged at around the same time 27,000-40,000 years ago.
