If you were walking through a dark forest in ancient Japan, you might hope to run into an okuri-ōkami, a wolf that would escort you safely to your destination. This creature of folklore may be based on the Japanese wolf, a border colliesize animal with short legs and stubby ears that lived in Japan for thousands of years until humans wiped it out in the early 20th century. Now, scientists studying ancient DNA from this wolfs bones say they may have solved the long-standing mystery of where it came from: a vanished population of gray wolves in East Asia that also gave rise to modern dogs.
Its a very meticulous study, says Peter Savolainen, a geneticist at the Royal Institute of Technology in Stockholm who was not involved. The research, he says, adds evidence to the idea that dogs arose in East Asia, as he and other researchers suspect, rather than in Europe or the Middle East, as some experts have proposed.
All of todays dogs likely descend from a single population of gray wolves. But exactly where and when those wolves lived has long been a source of contentious debate. Part of the problem is that although the species persists, that original population has likely vanished, wiping out genetic clues about doggy origins.
Enter the Japanese wolf (Canis lupus hodophilax). Described by some as one of the greatest mysteries in the history of Japanese zoology, the animals origins are unclear, as is the route it took to reach Japan. A genetic analysis of remains from a single Japanese wolf published earlier this year found it was closely related to a lineage of Siberian wolves, long thought extinct. Recent evidence also suggests dogs may have arisen in Siberia. Might Japanese wolves and dogs share more than just geography?

(so - more so than Gray wolves themselves? that's - surprising.)

That wolf is cool to look at though.

It wouldn't surprise me at all if dogs descended from various wolves, though.
Silver foxes in Russia became VERY dog-like after being selected for tameness, and it didn't take long for that transformation to occur either. It wasn't just a change in fox behavior -- barking, beckoned by their names, etc. -- but their appearance too -- curled tails, floppy ears, variations in fur color and such.
And foxes and wolves aren't even in the same species, of course.
