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]
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 ...
One left mandible paired with the right maxilla, proposed as a Paleolithic dog. [26] 31,000 : Predmostí, Moravia, Czech Republic: Three dog-like skulls proposed as being Paleolithic dogs. [26] Predmostí is a Gravettian site. The skulls were found in the human burial zone and identified as Palaeolithic dogs, characterized by – compared to ...
Dogs have made 11 vertebrate species extinct and are identified as a 'potential threat' to at least 188 threatened species worldwide. [162] Dogs have also been linked to the extinction of 156 animal species. [163] Dogs have been documented to have killed a few birds of the endangered species, the kagu, in New Caledonia. [164]

Dogs were brought to the Americas about 10,000 years BCE (Before Common Era) [3] and made their way to South America sometime between 7,500 and 4,500 BCE. [1]While American dogs were once believed to be descended from American grey wolves, recent studies have concluded that the Native American dogs descend from Eurasian grey wolves and were brought to America when the first peoples migrated ...
