The red wolf is an enigmatic taxon, of which there are two proposals over its origin. One is that the red wolf is a distinct species (C. rufus) that has undergone human-influenced admixture with coyotes. The other is that it was never a distinct species but was derived from past admixture between coyotes and gray wolves, due to the gray wolf ...
A domestic long-haired cat is a cat of mixed ancestry – thus not belonging to any particular recognized cat breed – possessing a coat of semi-long to long fur. Domestic long-haired cats should not be confused with the British Longhair, American Longhair, or other breeds with "Longhair" names, which are standardized breeds defined by various registries. [8]
The Lykoi (commonly called wolf cat or werewolf cat) is a breed of cat derived from a natural mutation causing a form of hypotrichia (e.g. congenital alopecia) [1] found in domestic short-haired cats. The mutation has occurred in domestic cats over the last 20 years.
The gray wolf (C. lupus), the Ethiopian wolf (C. simensis), eastern wolf (C. lycaon), and the African golden wolf (C. lupaster) are four of the many Canis species referred to as "wolves". [37] Species that are too small to attract the word "wolf" are called coyotes in the Americas and jackals elsewhere. [ 38 ]
A North American wolf. The wolf is the largest extant member of the family Canidae, [32] and is further distinguished from coyotes and jackals by a broader snout, shorter ears, a shorter torso and a longer tail. [33] [32] It is slender and powerfully built, with a large, deeply descending rib cage, a sloping back, and a heavily muscled neck. [34]
In 2021, a mitochondrial DNA analysis of North American wolf-like canines indicates that the extinct Late Pleistocene Beringian wolf was the ancestor of the southern wolf clade, which includes the Mexican wolf and the Great Plains wolf. The Mexican wolf is the most ancestral of the gray wolves that live in North America today. [18]

In 2016, a whole-genome DNA study suggested that all of the North American canids, both wolves and coyotes, diverged from a common ancestor 6,000–117,000 years ago. The whole-genome sequence analysis shows that two endemic species of North American wolf, the red wolf and eastern wolf, are admixtures of the coyote and gray wolf. [26] [27]
