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
White-tailed prairie dog describing current population trends. This denial is being reconsidered, because former deputy assistant secretary Julie MacDonald has been found to have improperly influenced the scientific basis of the denial. Groups such as the Biodiversity Conservation Alliance are working to legally protect this species.
