An extinct Late Pleistocene wolf may have been the ancestor of the dog. [5] [1] [6] The dog is a wolf-like canid. [7] [8] [9] The genetic divergence between the dog's ancestor and modern wolves occurred between 20,000 and 40,000 years ago, just before or during the Last Glacial Maximum [2] [1] (20,000–27,000 years ago). This timespan ...
[99] [12] [153] This suggests that none of the modern wolf populations are related to the wolves that were first domesticated and the wolf ancestor of dogs is therefore presumed extinct. [12] [153] Recent mitochondrial DNA analyses of ancient and modern grey wolf specimens supports a pattern of population reduction and turnover.
Caniformia is a suborder within the order Carnivora consisting of "dog-like" carnivorans. They include dogs (wolves, foxes, etc.), bears, raccoons, and mustelids. [1] The Pinnipedia (seals, walruses and sea lions) are also assigned to this group. The center of diversification for the Caniformia is North America and northern Eurasia.
Canidae (/ ˈ k æ n ɪ d iː /; [3] from Latin, canis, "dog") is a biological family of dog-like carnivorans, colloquially referred to as dogs, and constitutes a clade. A member of this family is also called a canid (/ ˈ k eɪ n ɪ d /). [4] The family includes three subfamilies: the Caninae, and the extinct Borophaginae and Hesperocyoninae. [5]
The lineages of modern dogs and wolves may have split thousands of years earlier than previously thought. According to new research, the divergence happened around 27,000 to 40,000 years ago, far ...
Domestic dogs come in more sizes than any other mammal species. Now, researchers say a genetic mutation that emerged in wolves before they were domesticated is responsible. Yes, those tiny dogs ...
[9] [7] Genetic studies show that dogs likely diverged from wolves between 27,000 and 40,000 years ago. [10] The dingo and the related New Guinea singing dog resulted from the geographic isolation and feralization of dogs in Oceania over 8,000 years ago. [11] [12] Dogs, wolves, and dingoes have sometimes been classified as separate species. [6]
A genome-wide study of a 35,000 YBP Pleistocene wolf fossil from northern Siberia indicates that the dog and the modern grey wolf genetically diverged from a common ancestor between 27,000 and 40,000 YBP. [23] [18] 33,500: Razboinichya Cave, Altai Mountains, Central Asia (Russia) The "Altai dog" is proposed as being a Paleolithic dog. [6]
