Dogs

The dog is a subspecies of the gray wolf , a member of the Canidae family of the mammilian order "Carnivora". The term "domestic dog" is generally used for both domesticated and feral varieties.
eage of dogs was domesticated from gray wolves about 15,000 years ago. Remains of domesticated dogs have been found in Siberia and Belgium from about 33,000 years ago. The earlier specimens not only show shortening of the snout but widening of the muzzle and some crowding of teeth making them clearly domesticated dogs and not wolves. There are more sites of varying ages in and around Europe and Asia younger than 33,000 years ago but significantly older than 15,000 years ago. None of these early domestication lineages seem to have survived the Last Glacial Maximum. Although mDNA suggest a split between dogs and wolves around 100,000 years ago no specimens predate 33,000 years ago that are clearly morphologically domesticated dog
