ID can't explain the gall bladder as well as evolution can. I recently had mine removed after 6 years of agonizing flare ups. The surgery is the most commonly performed in the U.S.
Now, I don't feel that an organ that is prone to stones and infections is very well designed.
However, from an evolutionary standpoint. Meat eating animals all have the gall bladder in common. It is an adaption for animals to help process meat.
Mechanisms of evolution have no intelligence behind them. So if a human suffers pain, as long as it doesn't interfere with reproduction (death, sterility, etc.) and passes on their genes, they are still part of the gene pool.
However, ID does posit intelligence behind biodiversity in a more direct manner. Since, IDers are fond of mechanical analogies, say a particular engine has a manufacturer's defect like a fuel leak. In, future models of this engine this problem will be addressed by engineers. So applying ID to animals, if God is directly involved in his designs as a human designer is, answer this..
Why is faulty design present?
Conversely, faulty design in biological organisms are incorporated into future offspring as long as it doesn't hinder reproduction. Like the gall bladder. My ancestors could have all dropped dead from infection at 34, as long as they produced offspring.
To use the mechanical analogy, it would be like designing cars to work despite defects as long as they sold. Also, incorporating the faulty design into future models. Once they rolled out of the showroom, the flaws would cause the car to breakdown.
Is that easy to understand shinbits?

So we should replace evolution, a useful theory with real world application, with ID, a theory that just says "something designed it" but doesn't say who or how?
How is ID better then? It could explain everything, but not the mechanisms of how it was created. Moreover, since it stops at saying only that a creator exists, it has no application.
