This could be potentially interesting for the crevo debate in regards to the ability of mutation.

The unique case here is that most anti-evos accept that different dog breeds share a common ancestor. I think we are near to finding out the exact nature of the genetic changes which were necessary to produce such different breeds of dogs. It will be interesting to see the differences due to mutation. I expect that a lot of the variation in physical structure between breeds will be due to mutation of some key genes.

Dog breeds might end up being a good demonstration of the ability of mutation, just as the peppered moth is a good demonstration of the ability of natural selection.

I've often used dogs as an example of a ring species, since, say, chihuahuas and great Danes cannot (AFAIK) mate, but there is a continuum of other breeds of intermediate size.

Remember that Darwin used pigeon breeding as one of his main examples.
