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.
According to this new tree, the largest clade of domestic dogs last shared a common ancestor 18,800 years ago, and collectively, they last shared a common ancestor with a wolf around 32,100 years ago. They must have been domesticated at some point during this window. These molecular dates fit with fossil evidence.
