ugh Taxonomy is a slog.
All domesticated dogs share a common ancestor, rather that Ancestor was a "wolf" is in debate, some say they fall into Canis lupus other says they don't, what is known is that based on there genes wolfs and dog's distinct lineage and what overlap they do have is likely from domesticated dogs breeding with wolfs and not from them sharing an ancestor. there are sematic arguments about rather the Paleolithic dog was a "dog "wolf" or other unnamed canine but it is accepted that dog's do not come from the same Lineage as wolfs just like say coyotes or jackals don't.
