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.
This is a list of maximum recorded animal lifespans in captivity.Only animals from the classes of the Chordata phylum are included. [1] On average, captive animals (especially mammals) live longer than wild animals.
The eastern wolf (Canis lycaon [5] ... [20] and the earliest age of dispersal for young eastern wolves is 15 weeks, much earlier than gray wolves. [49] ...
Dentition of an Ice Age wolf showing functions of the teeth. In 2007, a study was undertaken on the skeletal material from 56 Pleistocene-period East Beringian wolves from permafrost deposits in Alaska. Uncalibrated radio carbon dating showed a continuous population from 45,500 years BP to 12,500 years BP, and one single wolf dated at 7,600 BP.
The dire wolf (Aenocyon dirus [10] / iː ˈ n ɒ s aɪ. ɒ n ˈ d aɪ r ə s /) is an extinct canine. The dire wolf lived in the Americas during the Late Pleistocene and Early Holocene epochs (125,000–9,500 years ago). A putative, controversial fossil was recently reported from northeast China, but other researchers questioned the taxonomic ...

Species of the infraorder Cetacea A phylogenetic tree showing the relationships among cetacean families. [1]The evolution of cetaceans is thought to have begun in the Indian subcontinent from even-toed ungulates (Artiodactyla) 50 million years ago (mya) and to have proceeded over a period of at least 15 million years.
