At the heart of design science is the notion of irreducible complexity. Prediction-- take a biological structure, remove a component and it will fail to function. Test--I will leave the technical problem of testing to someone better prepared than I am. Falsifying Observation--the structure would continue to function without the component.

Okay. The human body is a biological structure. Remove the appendix through a common surgical procedure, and the human body continues to function.

There. Your "Design theory" has already been falsified.

The human body is obviously not an irreducible complex biological structure.

Ho, ho! Joke's on you! Didn't you know that the appendix is the seat of the soul? The body may continue on for a time, but the person roasts in Hell the while.
