Wolves are large, predatory canids once common throughout North America, Europe, Africa and Asia, now living mostly in remote wilderness. They are the largest living members of the canid family, which also includes foxes and coyotes.Wolves are the ancestors of all domestic dogs.There are two species of wolves in North America. The smaller species is the red wolf, Canis rufus, which has shorter, redder fur than the gray wolf. The gray wolf, Canis lupus, has thicker fur which is more gray or golden, and is larger than the red wolf.olves are large, predatory canids once common throughout North America, Europe, Africa and Asia, now living mostly in remote wilderness.

Although it was closely related to the Gray Wolf and other sister species, Canis dirus was not the direct ancestor of any species known today. Unlike the Gray Wolf, which is of Eurasian origin, the Dire Wolf evolved on the North American continent, along with the Coyote.(There is also a theory that it has evolved in South America, but that theory is less plausible.) The Dire Wolf co-existed with the Gray Wolf in North America for about 100,000 years.lthough it was closely related to the Gray Wolf and other sister species, Canis dirus was not the direct ancestor of any species known today.
