Calibration of the molecular clock suggests that the ancestors of modern dogs formed a distinct lineage prior to the peak of the last ice age. A dog’s DNA pairs that are unique from a wolf = 25 million! He and his colleagues compared dog and wolf DNA to learn which genes were important for domestication. They gathered full gene sequences from a wolf in Israel, a wolf in China and a wolf in Croatia to encompass the possible sites of the original dog domestication. It is easy to fantasize about having a deep emotional connection to a wolf. a The approximate geographic origin of the village dog (circles) and gray wolf (triangles) genome samples included in our analysis.
