For instance with dogs, you don't see one dog being born with two toes or one toe/hoove and it being beneficial. If we did, then I might agree with you. If we have seen any evidence of beneficial mutations in horses that have been or potentially are being naturally selected then I think you would have an argument.
Actually you do. My example does not include horses or dogs though. I have had several cats that are born with six toes. Were these six toes beneficial to the cat species and there by increasing their diversity throughout the population? Probably not, but that doesn't matter. The fact is, they did breed regardless of wether or not their mutation was beneficial, and quess what? six toed kittens. Not all but some from the liter. Who then will go on to spread the mutation to other cats down the line.

First off your cat didn't develop a new feature like a hoof. It had a mutation that effected an existing feature...the toe.
Oh well now you are moving the goalposts then, huh? No one in this thread has claimed that any creature we are comparing has made such an enormous jump without smaller transitional changes inbetween.
In the original message I replied to, this is what was said.

My reply was to illustrate that mutations occur and spread throughout populations regardless of whether or not they are beneficial.

Re: Is mesohippus more or less different from eohippus than dogs from wolf?
Third, the tooth sequences vary substantially. From the sequence of incisor-canine-premolar-grinding molar we see the following: H=3-1-4-3, O=3-1-3-4, and E=3-1-2-5, M I couldn't find. Again we see stasis in wolf/dog teeth. In fact dog diets have changed substantially over about 2000 known years of history, and the teeth have shown stasis.
It seems like the tooth count would indicate a progression to adapt to more vegetarian diet. Can you be more specific as to how Dog diet has changed in the last two thousand years? Seems like dog food has not been around for that long for adaptation to be a factor. Also do you think two thousand years (I don't know why you picked that number) is really enough time to see marked changes in tooth structure? Where is the enviromental pressure for changes in tooth structure?
