The dog diverged from a now-extinct population of wolves 27,000–40,000 years ago immediately before the Last Glacial Maximum, [ 1 ][ 2 ] when much of the mammoth steppe was cold and dry. The domestication of the dog was the process which led to the domestic dog. This included the dog's genetic divergence from the wolf, its domestication, and ...
The dog (Canis familiaris or Canis lupus familiaris) is a domesticated descendant of the wolf. Also called the domestic dog, it was domesticated from an extinct population of wolves during the Late Pleistocene, over 14,000 years ago by hunter-gatherers, prior to the development of agriculture. The dog was the first species to be domesticated by ...
The earliest evidence for dogs in the Americas can be found in Danger Cave, Utah, a site which has been dated to between 9,000 and 10,000 years BC. These New World dogs have been shown to descend from Old World Eurasian grey wolves. [2] In 2018, a study compared sequences of North American dog fossils with Siberian dog fossils and modern dogs.
Description. Diagram of a wolf skull with key features labelled. The Paleolithic dog was smaller than the Pleistocene wolf (Canis c.f. lupus)[1] and the extant grey wolf (Canis lupus), with a skull size that indicates a dog similar in size to the modern large dog breeds. The Paleolithic dog had a mean body mass of 36–37 kg (79–82 lb ...
Illustration of a Pleistocene wolf cranium that was found in Kents Cavern, Torquay, England [ 1 ] It is widely agreed that the evolutionary lineage of the grey wolf can be traced back 2 million years to the Early Pleistocene species Canis etruscus, and its successor the Middle Pleistocene Canis mosbachensis. [ 2 ][ 3 ] The grey wolf Canis lupus ...
Wolfdog. An Arctic wolf / Alaskan Malamute hybrid from Lobo Park, Antequera. Dog (domestic dog) A wolfdog is a canine produced by the mating of a domestic dog (Canis familiaris) with a gray wolf (Canis lupus), eastern wolf (Canis lycaon), red wolf (Canis rufus), or Ethiopian wolf (Canis simensis) to produce a hybrid.
The domestication of vertebrates is the mutual relationship between vertebrate animals including birds and mammals, and the humans who have influence on their care and reproduction. [ 1 ] Charles Darwin recognized a small number of traits that made domesticated species different from their wild ancestors. He was also the first to recognize the ...
A dog breed is a particular type of dog [ 1 ] that was purposefully bred by humans to perform specific tasks, such as herding, hunting, and guarding. Dogs are the most variable mammal on Earth, with artificial selection producing upward of 360 globally recognized breeds. [ 2 ] These breeds possess distinct traits related to morphology, which ...
