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
Dog type the written standard and awards are based on how closely the dog resembles the standard. Note 2. Many modern breeds of dogs still use the names of early types, although they may or may not resemble the old types. Note 3. Early attempts to categorize dogs as species of "Canis" are described by Carl Linnaeus in Systema naturae, 1758, Gmelin in 1788, Kerr in 1792.
