a better way of stating this is, "Increasingly subtle variations on increasingly dominant themes."

Yes, the creation model. All species existed at the beginning, but most have become extinct due to the changes caused by the judgement of the Earth, and the remaining species slowly, but perfectly adapt to those changes to the extent that the adaptability exists in their DNA. When they run out of geneticly provided adaptability, they become extinct too.
