Accidental evolutionists have had a rough time with things like why there are so many breeds of dogs:
There are big dogs, little dogs, hairy dogs, skinny dogs, dogs with floppy ears and dogs with pointed ears; dogs who bark loud but don’t bite and dogs that don’t bark much but bite hard. There are red dogs, white dogs, brown dogs, spotted dogs and all sorts of other color mixes. There are dogs with flat faces, dogs with pointed noses and dogs with long wiener-shaped bodies. There are bald dogs with smooth skin, skinny dogs with curly white hair and big hairy dogs with muscular, large bodies.
For what practical purpose did all these mutations take place? Biologists seem to be determined to link all of these various dog breeds to one master-dog—the wolf. Biologists have had to conjure up a strange accidental evolutionary process lasting a mere 10,000 years to explain how all these various breeds mutated from the wolf.
Biologists have tried to explain how the wolf was gradually bred by humans into more and more domesticated versions, accidentally yielding such crazy mutations like dachshunds (some call this pure-breed a “wiener dog”). How and why did this nutty-looking dog develop these characteristics? Why would these dogs mutate so quickly, and select these various features?
Certainly the features didn’t help them survive longer or better. In fact, in many cases these pure breed dogs actually die sooner than normal dogs, with ailments caused by malfunctioning organs inherent in that breed.

A few decades ago, a group of biologists performed dog-breeding research to attempt to explain how dogs have mutated from the wolf. Wolves and dogs were bred and domesticated over several years, and several generations of offspring were studied.
Through this research, these biologists observed that under some unknown mechanism, as the wolves were domesticated, they and their offspring gradually showed progressive physical and behavioral alterations. Their physical bodies began to develop features such as floppy ears instead of pointed ears, along with various other physical changes reflecting the increasing domestication.
Meanwhile their behavior became increasingly friendly towards humans. The biologists noticed also that these alterations were accompanied by an increased level of emotional chemicals like serotonin and dopamine. They guessed that these neurochemicals were somehow signaling genetic adjustments to cause the reshaping of physical features into future generations.

Note this neurochemical theory came to be a new twist on the accidental evolutionary theory, ascribing mutated variation to neurochemical changes. The existence of many of these neurochemicals only became known in the mid-twentieth century.
These researchers connected increases in neurochemistry through human contact; petting, feeding and other emotional expressions, with altered genes and physical characteristics. In other words, the more petting and human contact the animal received, the more this animal’s body began to alter.
The inclusion of behavior and emotion to explain genetic diversity opened a new factor for accidental evolutionists to wrestle with—the existence of a conscious living being.
