One author proposes that the Mexican wolf's ancestors were likely the first gray wolves to cross the Bering Land Bridge into North America during the Late Pleistocene after the extinction of the Beringian wolf, [17] colonizing most of the continent until pushed southwards by the newly arrived ancestors of the Great Plains wolf (C. l. nubilus).

Illustration of a Pleistocene wolf cranium that was found in Kents Cavern, Torquay, England [1]. It is widely agreed that the evolutionary lineage of the grey wolf can be traced back 2 million years to the Early Pleistocene species Canis etruscus, and its successor the Middle Pleistocene Canis mosbachensis.
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.
As of 2023, the Mexican wolf population stood at 257, a big gain for a species that was on the brink of extinction.. The number is a stark contrast to decades prior, when the species was close to ...
There were 257 Mexican wolves surviving in the range in 2023, a six-percent increase from the 242 lobos counted in 2022. 'Lobos' recovering in New Mexico, feds say. Questions linger on genetic ...
In 2021, a mitochondrial DNA analysis of modern and extinct North American wolf-like canines indicates that the extinct 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.
The Mexican wolf, a subspecies of the gray wolf, was listed as endangered in 1976, according to the U.S. Fish and Wildlife Service. Thousands of these animals once lived across New Mexico, Arizona ...
In a study that analyzed the molecular genetics of coyotes, as well as samples of historical red wolves and Mexican wolves from Texas, a few coyote genetic markers have been found in the historical samples of some isolated Mexican wolf individuals. Likewise, gray wolf Y chromosomes have also been found in a few individual male Texan coyotes. [28]
