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 traditional hypothesis of cetacean evolution, first proposed by Van Valen in 1966, [9] was that whales were related to the mesonychians, an extinct order of carnivorous ungulates (hoofed animals) that resembled wolves with hooves and were a sister group of the artiodactyls (even-toed ungulates). This hypothesis was proposed due to ...
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]
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 ...
The red junglefowl (Gallus gallus), often believed to be an ancestor of the domestic chicken.. Most animals are tuned to modern life by artificial selection. This is either due to the pressure of early hunter-gatherers' attempts to stabilise the food supply, which resulted in the existence of domesticated farm animals, or domestication of pets which are useful to humans.

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 ...
The conservation groups sued the U.S. Fish and Wildlife Service in 2020 after it stopped releasing captive-bred wolves. Eastern North Carolina is the only place in the world where they roam wild ...
The earliest known remains of wolves in Britain are from Pontnewydd Cave in Wales, dating to around 225,000 years ago, during the late Middle Pleistocene (Marine Isotope Stage 7). Wolves continuously occupied Britain since this time, despite dramatic climatic fluctuations. [4] The Roman colonisation of Britain saw sporadic wolf-hunting. [5]
