They didn't evolve into new species of dogs!!!!! They were bred .... And anyways your " science " says otherwise and that dogs are more closely related to the dingo than wolves .... A wolf didn't evolve into a lab or Shepard .... Wolves/dingos were domesticated and then bred with another canine species and this your current breed of domesticated dog was formed ..... I have had way too many responses that wolves evolved into a dog from this. ( if this is what you guy ls have as evolution then you are screwed )
