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 2018, a study compared sequences of fossil North American dogs with fossil Siberian dogs and modern dogs. The study indicates that dogs entered North America from Siberia 4,500 years after humans did, were isolated for 9,000 years, and after contact with Europeans these no longer exist because they were replaced with Eurasian dogs. The pre-contact dogs exhibit a unique genetic signature that is also now gone, with their nearest genetic relatives being the arctic breed dogs. In 2017, a study showed that 9,000 YBP the domestic dog was present at what is now Zhokhov Island, arctic north-eastern Siberia, which was
