Origin of the domestic dog Neolithic dog specimens with sequences from over 5,000 dogs and wolves. These Neolithic dog specimens included a dog sample from the Early Neolithic site in Herxheim, Germany dated 7,000 YBP, one from the Late Neolithic site of Kirschbaum (Cherry Tree) Cave near Forchheim, Germany dated 4,700 YBP, and one found in the Late Neolithic passage grave at Newgrange, Ireland dated 4,800 YBP. The study calculated a mutation rate for the 7,000 YBP Neolithic dog and found that it matched the mutation rate of the Taimyr-1 specimen, and noted that this also matched the mutation rate for the Newgrange dog that
Origin of the domestic dog the indigenous peoples of Siberia, East Asia, North America, and Australia. The domestic dog was the first species and the only large carnivore to have been domesticated. Over the past 200 years, dogs have undergone rapid phenotypic change and were formed into today's modern dog breeds due to artificial selection imposed by humans. These breeds can vary in size and weight from a teacup poodle to a giant mastiff. The skull, body, and limb proportions vary significantly between breeds, with dogs displaying more phenotypic diversity than can be found within the entire order of carnivores. Some breeds demonstrate outstanding skills
