Origin of the domestic dog. The dog diverged from a now-extinct population of wolves immediately before the Last Glacial Maximum, when much of Eurasia was a cold, dry mammoth steppe biome. 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.
