Whats the difference between a wild dog and a wolf?
Much debate has occurred over the relationship between the wolf and the domestic dog. Most authorities see the wolf as the dog’s direct ancestor, but others have postulated descent from the Golden Jackal. Because the canids have evolved recently and different canids interbreed readily, untangling the true relationships has presented difficulties. However, molecular systematics now indicate very strongly that domestic dogs and wolves are more closely related than either is to any other canid, and the domestic dog is now normally classified as a subspecies of the wolf: Canis lupus familiaris. The main differences between wolves and domestic dogs are that wolves have, on average, 30% larger brains, a better immune system, better sense of smell, and are generally much larger than domestic dogs.
