Evolution requires huge amounts of time for changes in species to manifest themselves. (This is why young-earth creationism is ridiculed, as is the Genesis flood — they do not allow enough time for goo-to-you evolution to occur.)

From the tiny Chihuahua to the massive mastiff, the over 200 breeds of domesticated dogs come in a wide variety of different body sizes and proportions, hair lengths and textures, and demeanors. Evolution asserts that animals change through a gradual accumulation of mutations. But evidence shows that the wolf-to-dog transition occurred rapidly, according to pre-designed genetic potential and not mutations.
Mark Derr, author of a new book titled How the Dog Became the Dog: From Wolves to Our Best Friends, discussed on National Public Radio's program Fresh Air how human interaction may have domesticated wolves beginning in the Ice Age. Since dogs are smaller than wolves and have more varying proportions, coat colors, and other features, interviewer Dave Davies asked Derr, "So how could this association of wolves with humans lead to these physical changes?"
