Intelligent Design Wins Again! (er, not)
When I was in high school, there was a girl who printed a list of quotes that she had heard every month, assigning each one to a particular day of the month. Each month, one of the quotes was "Marcia wins again!" And she had a perfect system, because she had enough friends who were interested in getting their name in print that someone would always find a way to ask, "So, who said 'Marcia wins again!' this month?", which of course meant that that person had said it.
The proponents of intelligent design are like that. If there is any tiny thing that Darwinian evolution cannot explain perfectly, that is, to them, an argument in favor of intelligent design. Because no matter what the case, intelligent design is the answer to all unanswered questions. One of the alleged arguments is that flagellum don't serve any purpose except in the organisms that have them, so somehow they couldn't have been selected for in natural selection. So naturally, they must be the product of intelligent design. This ignores two basic points of the scientific method. The first is that in natural selection, it is simply not the case that something can only be selected for because it has a valuable function. Many things can be selected for because they are dragged along with other characteristics that are selected for. Or the characteristic can be entirely neutral based on the pressures on the population at the time, and so be retained or even mutated in favor of randomly. We have no idea if there were organisms that didn't have flagella that didn't survive. But more importantly, we have no pure history of all the pressures that were on all populations of organisms throughout the history of the planet. So just because we cannot explain something today doesn't mean that it has no explanation entirely consistent with natural selection.
But you see, that's just a theory! So Intelligent Design can be a theory, too! And since Intelligent Design, using its tautological, Panglossian logic, has an answer to every question (even when the answer is "we cannot know the mind of the Intelligent Designer"), Intelligent Design Wins Again!
So Intelligent Design gave us the hantavirus, and the AIDS virus and bird flu and mad cow disease, and of course left us with Saddam Hussein and Osama bin-Laden and George W. Bush. Everything is perfect in this best designed of all possible worlds!
