However, in 2021, a study indicated the dire wolf to be a highly divergent lineage which last shared a most recent common ancestor with the wolf-like canines 5.7 million years ago. The morphological similarity between dire wolves and gray wolves was concluded to be due to convergent evolution. This finding indicates that the wolf and coyote ...
The long-term isolation of the dire wolf lineage implies that other American fossil taxa, including C. armbrusteri and C. edwardii, may also belong to the dire wolf's lineage. [13] In the 2024 study, the Armbruster's wolf is considered as a species of Aenocyon , while C. edwardii is considered more closely related to the modern coyote .
The dire wolf shared its habitat with the gray wolf, but became extinct in a large-scale extinction event that occurred around 11,500 years ago. It may have been more of a scavenger than a hunter; its molars appear to be adapted for crushing bones and it may have gone extinct as a result of the extinction of the large herbivorous animals on ...
The study proposes an early origin of the dire wolf lineage in the Americas, and that this geographic isolation also resulted in reproductive isolation, driving their divergence 5.7 million years ago. Concurrently, Coyotes, dholes, gray wolves, and the extinct Xenocyon ostensibly evolved in Eurasia and expanded into North America more recently ...
Gray wolf [31] [35] Canis lupus: Modern wolves are notably rarer at La Brea than the slightly larger dire wolves. One particular fossil preserves the femur of a wolf that survived a traumatic injury. The nature of the fossil suggests that the wolf's leg was either broken and developed a pseudarthrosis or that the leg was entirely amputated and ...

Cave wolf skull, Natural History Museum, Berlin. The Late Pleistocene era was a time of glaciation, climate change, and the advance of humans into isolated areas. [17] During the Late Pleistocene glaciation, a vast mammoth steppe stretched from Spain eastwards across Eurasia and over Beringia into Alaska and the Yukon.
