Is this mutt a wolf or a dog?
It could be that at its age it is genetically equidistant from modern domestic dogs and modern wolves. It could also plausibly represent a population from which dogs had already been drifting as a human-controlled population.
If the pup represents the dog branch, it'll be interesting to see finer hypotheses on how it's specific adaptations contributed to the lifestyle and mega-hunting in this harsh region.
