5. PBS wrongly claims that the Type III Secretory System (T3SS) refutes the irreducible complexity of the bacterial flagellum.
PBS features flagellum expert David K. DeRosier repeating the testimony of Ken Miller, claiming that the flagellum is not irreducibly complex because the T3SS "is a structure that functions that is missing several" of the proteins of the flagellum. In fact, this is not the correct test of irreducible complexity. Behe properly tests irreducible complexity by assessing the plausibility of the entire functional system to assemble in a step-wise fashion, even if sub-parts can have functions outside of the final system.
