During the Dover trial, proponents of Darwin’s theory claimed that the Type III Secretion System needle complex refuted Michael Behe by showing how the flagellum could have evolved from a simpler structure through a Darwinian process. But the scientific evidence now shows that the needle complex originated after the flagellum had already developed.
