Dogs are possibly the most widely varying species on the planet while still remaining a single species. In 20,000 years of artificial selection and preservation of variants that never would have survived in the wild there hasnít been a single variant with an anatomical feature not characteristic of canines nor has a new species of dog emerged.

The first tiny shrewlike mammals appeared about 150-195 million years ago. Yet DaveScot expects that the transition from wolf to toy poodle in a few thousand years is too slow to account for the change from shrewlike to dog in a period thousands of times longer.
