The first thing, where a species changes over many generations, and becomes something else.
For a being with divine unlimited powers, he sure did a pretty crappy Job with this place.
It often happens pretty much in a flash--evolution.
In Siberia the consortium which bought and sold fox fur decided to bring science into the process. Trapping and hunting foxes was not terribly productive, so with the assistance of the researchers they trapped live foxes and chose from among the subjects those which showed the best possibility for domestication.
They succeeded beyond their best expectations, but the success did not give them more fox fur. Within ten years the domesticated foxes grew longer legs, shorter snouts, much less fluffy tails. The tails curled, changed color and the foxes were much more dog-like than fox-like.
The dog is the most malleable life-form on the planet (at least speaking in terms of mammals). New breeds can be created and lost entirely within a handful of generations.
Now, I believe in Creation and in Evolution. Both are logical decisions to me, and I find no problem embracing both. The living cell is amazing in its mutability. To quote Dr. Crichton: "Life will find a way."
