Dogs and wolves are the same exact species (Canis Lupus). They've only been separated for a measly 15,000 years. I'm pulling the following out my ass but it makes sense since our species left Africa between 125K and 60K years ago and our average life-span is about 4-5x that of wolves/dogs so it makes sense... There's probably more genetic difference between a Korean and a Nigerian than between a wolf and a dog. At the very least, the Korean's ancestors were separated from the ancestors of the Nigerian AT LEAST as many generations as dogs are separated from wolves. I don't think most people realize that Fido is a wolf through and through.
