This was followed by an explosion of Canis evolution across Eurasia in the Early Pleistocene around 1.8 million YBP in what is commonly referred to as the wolf event. It is associated with the formation of the mammoth steppe and continental glaciation. Canis spread to Europe in the forms of C. arnensis, C. etruscus, and C. falconeri. [23]
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.
The study proposes that after having diverged from the common ancestor shared with the grey wolf, the evolution of the dog proceeded in three stages. The first was natural selection based on feeding behaviour within the ecological niche that had been formed through human activity. The second was artificial selection based on tamability.
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 ...
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. [2] Cetaceans are fully aquatic mammals belonging to the order Artiodactyla and branched off from other artiodactyls around 50 mya.
Arctic wolf feeding on muskox carcass in Ellesmere Island. Very little is known about the movement of the Arctic wolves, mainly due to climate. The only time at which the wolf migrates is during the wintertime when there is complete darkness for 24 hours. This makes Arctic wolf movement hard to research.
The wolf-sized C. chihliensis appeared in northern China in the Mid-Pliocene around 4-3 million YBP. This was followed by an explosion of Canis evolution across Eurasia in the Early Pleistocene around 1.8 million YBP in what is commonly referred to as the wolf event.
The second largest subspecies of wolf, second in skull and tooth proportions only to occidentalis (see chart above), with fur that is black, white or a mixture of both in color. [78] The Alaskan Interior and Yukon, save for the tundra region of the Arctic Coast [79] Currently (2025) synonymized under C. l. occidentalis [1] [80] C. l. nubilus ...
