These studies assumed that the extant wolf was the ancestor of the dog, and did not consider genetic admixture between wolves and dogs, or the impact of incomplete lineage sorting. These pre-genomic studies have suggested an origin of dogs in Southeast Asia, East Asia, Central Asia, the Middle East, or Europe.
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]
One authority has classified the Paleolithic dog as Canis cf. familiaris [1] (where cf. is a Latin term meaning uncertain, as in Canis believed to be familiaris).Previously in 1969, a study of ancient mammoth-bone dwellings at the Mezine paleolithic site in the Chernigov region, Ukraine uncovered 3 possibly domesticated "short-faced wolves".
Caninae (whose members are known as canines (/ k eɪ n aɪ n z /) [6]: 182 is the only living subfamily within Canidae, alongside the extinct Borophaginae and Hesperocyoninae. [7] [1] They first appeared in North America, during the Oligocene around 35 million years ago, subsequently spreading to Asia and elsewhere in the Old World at the end of the Miocene, [6]: 122 some 7 million to 8 ...
Modern free-ranging dogs differ in origin from North to South America. In North America, the Carolina dog has mtDNA links to East Asian dogs, with a shared haplotype with the Shiba Inu in Japan. This suggests that it migrated to North America through Beringia, therefore making it a Native American dog. In South America, on the other hand, free ...
The Canaan Dog (Hebrew: כלב כנעני; Arabic: كلب كنعاني) is a dog breed developed in the early 20th century [3] [4] from semiwild pariah dogs that were the descendants of animals present in the region since biblical times. [2] It can be found in Israel, Jordan, Lebanon, Palestine, [5] and the Sinai Peninsula.

A study of the estimated bite force at the canine teeth of a large sample of living and fossil mammalian predators, when adjusted for their body mass, found that for placental mammals the bite force at the canines (in Newtons/kilogram of body weight) was greatest in the extinct dire wolf (163), followed among the modern canids by the four ...
