In 2017, the wolf research scientist L. David Mech queried why evolutionary biologists were calculating the approximate time of the dog diverging from the wolf through using a wolf generation time of three years when published works using large data sets demonstrate a figure of 4.2–4.7 years. They were encouraged to recalculate their ...
Canis lepophagus (Latin: canis: 'dog'; lepus: 'hare' or 'rabbit'; suffix -phagus: '-eating'; hence hare-eating dog) is an extinct species of canid which was endemic to much of North America during the Early Pliocene. [2] It is notable because its lineage is proposed to have led to both wolves and coyotes.
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.
A large wolf, it was found all over North and Central America and was eventually supplanted by the dire wolf, which then spread into South America during the Late Pleistocene. [15] By 0.3 Mya, a number of subspecies of the gray wolf (C. lupus) had developed and had spread throughout Europe and northern Asia. [16]
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 Beringian wolf is an ecomorph of the gray wolf and has been comprehensively studied using a range of scientific techniques, yielding new information on their prey species and feeding behaviors. It has been determined that these wolves are morphologically distinct from modern North American wolves and genetically basal to most modern and ...
The separation of the dog and wolf did not have to coincide with selective breeding by humans. [45] [47] Such an early divergence is consistent with several paleontological reports of dog-like canids dated up to 36,000 YBP, as well as evidence that domesticated dogs most likely accompanied early colonizers into the Americas.

Carnivora (/ k ɑːr ˈ n ɪ v ər ə / kar-NIH-vər-ə) is an order of placental mammals specialized primarily in eating flesh, whose members are formally referred to as carnivorans.
