Question

where did the first dog come from earth?

Answer 1

The origin of the domestic dog is not clear. The domestic dog is a member of genus Canis (canines) that forms part of the wolf-like canids, and is the most widely abundant carnivore.The closest living relative of the dog is the gray wolf and there is no evidence of any other canine contributing to its genetic lineage. The dog and the extant gray wolf form two sister cladeswith modern wolves not closely related to the wolves that were first domesticated.The archaeological record shows the first undisputed dog remains buried beside humans 14,700 years ago,with disputed remains occurring 36,000 years ago.These dates imply that the earliest dogs arose in the time of human hunter-gatherers and not agriculturists. The dog was the first domesticated species.

Answer 2

Scientists have looked at DNA inherited exclusively from the mother (called mitochondrial) and DNA inherited exclusively from the father (the Y-chromosome) and suggested that dogs were first domesticated in China, south of the Yangtze River.

However, the oldest dog bones anyone has found are from the other end of Eurasia, all the way in Northern Europe. Furthermore, the mitochondria of modern dogs are closely related to the mitochondria of ancient European wolves.
