Black wolf

Not attested as a mythic origin in the provided sources. The material documents a biological origin for black pelage in many wolf populations—genetic research cited in scientific summaries shows the black coat mutation originated in domestic dogs and was carried into some wolf populations via hybridization—rather than a folkloric or cosmological origin story.

Described in the sources as a wolf whose pelt is melanistic (predominantly black). Apart from coat and knee colour, sources state black wolves are morphologically normal gray wolves; historical naturalist accounts sometimes described individual black specimens as larger or stronger, but no consistent non-colour morphological differences are documented.

No supernatural powers are documented in the supplied sources. Behavioural attributions recorded are ethnographic or observational impressions: in Tibet black wolves (locally called chanko nagpo) were considered bolder and more aggressive than pale-coloured wolves, while some European naturalists reported black wolves as less aggressive or more prone to interbreed with dogs. Modern genetic studies explain coat colour through a dog-origin mutation introduced by hybridization, accounting for appearance but not any supernatural ability.
