To get the full variety of modern species from the animals who can fit on a boat you need vast physical and genetic changes extremely quickly.Animals don't warp and twist when they change species. If they did there would be mostly transitional forms in the fossil record and there is not. Most people are hard pressed finding any characteristic forms that are "half-formed".
One researcher did breeding on a wolf pack. By breeding based on attitude or character traits the animals changed so much in just a few generations that they stopped the experiment because the wolves bred with a mild temperament were becoming too small and timid to survive back in the wild. So they stopped the selective breeding.
If you got a fennec fox and a red fox from the same population of "fox kind" they would look warped and deformed. Even though they are both sound animals, they are hardly the same.
