I can see how changing a wolf into a Chihuahua could make someone question evolution! However, this process can be explained by naturally occurring mutations and selection by humans.
Recent studies of the dog DNA sequence have shown that dogs were most likely domesticated from East Asian wolves 15,000 years ago or more. The appearance of the domestic dogs varies tremendously between different breeds. For example compare a tiny 1 pound Chihuahua to a 160 pound Mastiff or a Great Dane.
Now, what about wolves and dogs. Is the fact that dogs are closely related to wolves compatible with the theory of evolution? The short answer is yes, but the underlying reasons require some clarification.
