Thank you, John. Now, if you don't mind, let me rephrase your original message: Wolfhounds are from eastern Europe and have a lanky, slender build, long narrow skulls and long, frequently bushy tails. Chihuahuas are from Mexico, are small, have rounded heads with bulgy eyes and short hair. There are also other differences between the two species, such as seed [naughty words suppressed] size. The hybrid between them, the so-called hairless wolf-rat, has the habit of the Chihuahua but is more slender. If my memory is correct... Do you get my point? Remember, organisms are not members of the same species because they look alike, they look alike because they are members of the same species. And other members of that same species may not share the same characteristics. Think of Magnolia liliiflora and M. denudata as different ends of the same rope, a rope woven of varying materials.
