[126] [134] [125] [129] There possibly existed a panmictic wolf population with gene flow spanning Eurasia and North America until the closing of the ice sheets. [126] [135] [129] Once the sheets closed, the southern wolves were isolated and north of the sheets only the Beringian wolf existed. The land bridge became inundated by the sea 10,000 ...
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]
As wolves had been in the fossil record of North America but the genetic ancestry of modern wolves could be traced back only 80,000 years, [22] [23] the wolf haplotypes that were already in North America were replaced by these invaders, either through competitive displacement or through genetic admixture. The replacement in North America of a ...
Commencing in 2016, two studies using whole genome sequencing indicate that North American gray wolves and wolf-like canids were the result of ancient and complex gray wolf and coyote mixing, [11] [12] with the Great Lakes wolf possessing 25% coyote ancestry and the Algonquin wolf possessing 40% coyote ancestry.

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.
In Russia's far northeastern Yakutia region, local scientists are performing an autopsy on a wolf frozen in permafrost for around 44,000 years, a find they said was the first of its kind. Found by ...
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 ...
