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.
The term domestic dog is generally used for both domesticated and feral varieties. The English word dog comes from Middle English dogge, from Old English docga, a powerful dog breed. The term may possibly derive from Proto-Germanic *dukkÅn, represented in Old English finger-docce (finger-muscle).
