As wolves had been in the fossil record of North America but modern wolves could trace their ancestry back only 80,000 years, the wolf haplotypes that were already in North America were replaced by these invaders, either through competitive displacement or through admixture. [129]
Wolf after re-introduction. The history of wolves in Yellowstone includes the extirpation, absence and reintroduction of wild populations of the gray wolf (Canis lupus) to Yellowstone National Park and the Greater Yellowstone Ecosystem. When the park was created in 1872, wolf populations were already in decline in Montana, Wyoming and Idaho.
The wolf (Canis lupus; [b] pl.: wolves), also known as the grey wolf or gray wolf, is a canine native to Eurasia and North America. More than thirty subspecies of Canis lupus have been recognized, including the dog and dingo , though grey wolves, as popularly understood, only comprise naturally-occurring wild subspecies.
In British-ruled India, wolves were heavily persecuted because of their attacks on sheep, goats and children. In 1876, 2,825 wolves were bountied in the North-Western Provinces (NWP) and Bihar. By the 1920s, wolf eradication remained a priority in the NWP and Awadh. Overall, over 100,000 wolves were killed for bounties in British India between ...
Red wolves were once distributed throughout the southeastern and south-central United States from the Atlantic Ocean to central Texas, southeastern Oklahoma and southwestern Illinois in the west, and in the north from the Ohio River Valley, northern Pennsylvania, southern New York, and extreme southern Ontario in Canada [2] south to the Gulf of Mexico.

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. [17]
The northwestern wolf (Canis lupus occidentalis), also known as the Mackenzie Valley wolf, [5] Alaskan timber wolf, [6] or Canadian timber wolf, [7] is a subspecies of gray wolf in western North America. Arguably the largest gray wolf subspecies in the world, it ranges from Alaska, the upper Mackenzie River Valley; southward throughout the ...
[46] [19] [31] Tedford proposed that C. armbrusteri was the common ancestor for both the North and South American wolves. [39] Later studies concluded that C. dirus and C. nehringi were the same species, [40] [47] and that C. dirus had migrated from North America into South America, making it a participant in the Great American Interchange.
