The New Guinea Singing Dog has been rediscovered in the wild. The World's Rarest and Most Ancient Dog Has Just Been Re-Discovered in the Wild
Yes but it's a pariah landrace. NGSDs differ from Australian and Thai dingoes about as much as Andean Indians differ from Amazonian Indians - stockier and uplands adapted but very questionable as a subspecies. In the past it was questioned whether the dingo/NGSD was a true Canis familiaris or from a separate ancestor - even Cuon alpinus was implicated in the past. Nowadays such names as C.f.hallstromi are redundant because no one uses equivalent trinomials for similar populations like the basenjis. If people want to use them - after all there is no objective measure - they should be consistent. But people aren't.
That's what I meant the other day with the official species lists being a problem: pariah dogs are a grade between wild Canis and "proper" domestic dogs: the Thai and Aussie dingoes are usually included by default but not usually things like basenjis or telomians that belong to the same grade: this is scarcely a valid construct. Furthermore animals gone feral will begin to resemble the wild ancestor, I question that all pariah dogs belong to a pristine grade, even: nowadays people are studying pariah landrace stocks like Carolina dogs more closely so the full picture will emerge.
