Type III Secretion System

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.
