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 result of a female wolf/male dog pairing. Haplogroup A: Includes 64-65% of dogs. Haplotypes of subclades a2–a6 are derived from post-domestication wolf–dog hybridization. Haplogroup B: Includes 22-23% of dogs. haplotypes of subclade b2 are derived from post-domestication wolf–dog hybridization. Haplogroup C: Includes 10-12% of dogs. Haplogroup D: Derived from post-domestication wolf–dog hybridization in subclade d1 (Scandinavia) and d2 (South-West Asia). The northern Scandinavian subclade d1 hybrid haplotypes originated 480-3,000 YBP and are found in all Sami-related breeds: Finnish Lapphund, Swedish Lapphund, Lapponian Herder, Jamthund, Norwegian Elkhound and Hällefors Elkhound. The maternal wolf sequence that contributed to them has not been
