How Do Darwinians Explain the Flagellum?

How do the Darwinists interpret the whip? in the same way that they interpret the whip; that is, using a tactful silence, sometimes with some stories! There is currently a lively debate in the literature about the flagellum and another structure called the TTSS, which contains a number of protein parts resembling the flagellum. Bacteria use this secretory system as a protein pump; when building a flagellum there is also a pump used to build it, so some researchers believe that the two are related to a common ancestor. But there are no scientific papers that seriously talk about how either of these two structures can combine through random mutations and natural selection, or even how one of the two structures can be derived from the other through Darwinian processes!!! Take a review of the whip assembly written by Yale University biologist Robert Macnab shortly before his early death in 2003. In the article, Robert Macnab showed great breadth of knowledge, summarizing the enormously complex path of the whip assembly. How could such a path develop through random mutations? In a review of nearly 7,000 words, the word “natural selection” did not appear. The word “evolution” or one of its derivatives appeared once in the last sentence of the article. Speaking about the whip and the type III secretion system, Robert McNab wrote: "It is clear that nature has found two good uses for this complex type of device. How [the whip and type III secretion system] evolved is another matter, although it has been suggested that the whip is older than the secretion system, because it is present in microbial species that diverged long before the emergence of a true-core host as a target for microbial virulence." In short, Darwinism has nothing more to say. - Dr. Michael Behe. — Source: Published on Facebook's "Braheen Center" page
