Interesting that they got this wrong. Oldest identified dog remains are 14,000 to 18,000 years old from Siberia.

What makes a dog a dog is behavior, not appearance. A dog-looking wolf or jackal is a wolf or jackal, and visa versa. You can't tell from a fossile if a creature attacked small children or befriended them. This is the type of going far beyond all evidence that should mark the so-called scientist who comes up with this stuff as a crank.

"What makes a dog a dog is behavior, not appearance."

Actually dogs are a subspecies of wolves and are not closely related to coyotes or jackals. The difference between dogs and most species of wolves is visible to the naked eye (if you know what bones to look for). Behavior does make a huge difference though and this is why I favor a single speciation event. That aside wolves have been hanging around genus homo for ~400,000 years. If they were attacking children I'm sure the humans would have exterminated them. Destroying a wolf pack is pretty easy.

As for all this being crank, well let's just say the evidence is piling up. This is the life's work of many people and I for one am glad to sit back and delight in what they find.
