It would take generations of breeding the tamest ones, with the behaviors you wanted, to get something like the beginnings of domesticated dogs.

It also makes me wonder about the longlasting question of speciation. If it happens suddenly, shouldn't that indicate a singular (or near-singular) instance of mutation?
