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.
Its genetic diversity was higher than that of its modern counterparts, implying that the wolf population of the Late Pleistocene was larger than the present population. Modern North American wolves are not their descendants, and this supports the existence of a separate origin for ancient and extant North American wolves. [5]
Coyotes from Missouri, Illinois, and Florida exhibit 5–10% wolf ancestry. There was 40%:60% wolf to coyote ancestry in red wolves, 60%:40% in eastern wolves, and 75%:25% in the Great Lakes wolves. There was 10% coyote ancestry in Mexican wolves, 5% in Pacific Coast and Yellowstone wolves, and less than 3% in Canadian archipelago wolves. [12]
The eastern wolf has two proposals over its origin. One is that the eastern wolf is a distinct species (C. lycaon) that evolved in North America, as opposed to the gray wolf that evolved in the Old World, and is related to the red wolf. The other is that it is derived from admixture between gray wolves, which inhabited the Great Lakes area and ...
Reintroduction of wolves. Wolves were reintroduced to the park in 1995, after being driven extinct in the area nearly 100 years ago. It is estimated that approximately 500 wolves are present now ...
Extirpated from the wild in the early 1970s and reintroduced in 1998. [30] Texas red wolf: Canis rufus rufus: Central Texas to southern Louisiana Extinct in the wild by 1980 and introduced (in lieu of the extinct subspecies) to eastern North Carolina in 1987. The species is threatened by human persecution and hybridization with coyotes. [31]
Beringian wolves possessed a craniodental morphology that was more specialized than modern gray wolves and Rancho La Brea wolves for capturing, dismembering, and consuming the bones of very large megaherbivores, [8] [18] having evolved this way due to the presence of megafauna. [53] Their stronger jaws and teeth indicate a hypercarnivorous ...
A California gray wolf, dubbed OR 85, in 2023. The wolf was fitted with a satellite collar to help the California Department of Fish and Wildlife track the state's burgeoning wolf population.
