The Chihuahua dog is or is not evolution by human selection, wolf or selective breeding?
Someone told me that is not a Chihuahueñ human intervention, instead of this dog has changed, probably gray wolves like other dogs, but by means of natural selection. Is this true? What is the evidence?
Dogs of different breeds, including Chihuahuas are the result of reproduction selectively by humans for certain features. However, dogs evolved from wolves. Selective breeding of them in different races came much later. "Fossil and genetic testing confirmed that all dogs are descendants of wolves. In fact, the skeletons of the first dogs and their wild cousins of the wolf may be difficult to distinguish. "
