DNA tests seem to indicate that all dog breeds descend from a gray wolf. (Dogs, coyotes, wolfs & foxes can interbreed and therefore represent a "kind"). Russian scientests selected foxes for "tameness" in an experiment. Weeding out for aggressive or fear avoidance tendencies took only 3 generations to stabalize. (Not thousands of years). And by the 6th generation fox pups were as friendly towards humans as there dog pup counterparts.
