The Beginning of a Beautiful Friendship: Canine Domestication How a wolf could transform from suspicious‚ wild beast to obedient‚ cuddly Fido may seem mystifying or even unbelievable. But scientists have used DNA evidence to show that‚ more than likely‚ the dog did indeed descend from the gray wolf. Although the oldest fossils of a domesticated dog are from a 14‚000-year-old dog grave‚ DNA evidence suggests dogs diverged from wolves much earlier than that (with estimates ranging from 15‚000 to
