The Evolution of Dogs

The complete DNA genome has been sequenced not only of wolves but dozens of breeds of dogs, purebred dogs with different features. It turns out that to a very large extent it's due to breaking genes that were already there. So we did show how Darwin's theory works by artificial selection but it's working by breaking genes. You can never breed a dog that will become a giraffe or a horse, you can never break out of the dog wheel rut so to speak.
