The article states that the rotor very much evolved. But if you follow the linked evidence, various flagellar motors appear to have evolved from an original ancestor. This is exactly consistent with intelligent design and creationism. It does not demonstrate the origin of the flagellar motor in the first place. Everyone, whether creationists, theistic evolutionists, or materialistic evolutionists all agree that mutation, natural selection, genetic drift, gene flow etcetera occur. This paper advances the debate about origins no further distance. The debate is not about the survival of the "fittest", the debate is about the arrival of the fittest.
