It's simpler than that. When evolution is outlawed, all biology books are burned, and all biologists are ordered by the red guards (or perhaps blue guards?) into the fields to do brute agricultural labor, then everything will automatically be seen to have been Designed, as no other possibility will be permitted. Biology will then consist of a long list of 1.75 million unrelated, specially-created species. When that glorious day arrives, there will be no more crime, no more war, no more racism, no more poverty, no more disease, and no more sin in the world. Just as it was before Darwin.
