Eh? What's the evidence for that? If it's evidence from developmental biology, then it's no evidence against evolution.

A glimpse of a simpler system with a simpler function
The flagellar research community received a surprise two years ago from a downsized relative of Escherichia coli, the aphid endosymbiont, Buchnera aphidicola. Although nonmotile, this intracellular bacterium possesses all the genes necessary for hook–basal–body biosynthesis, although it lacks any of the genes for filament assembly, including the gene for flagellin. In late 2006, a group of Japanese researchers showed that the Buchnera cell surface is studded with hundreds of hook–basal–body complexes [7]. These remarkable structures provide a glimpse of a cut-down flagellar system that must have some role other than motility – probably the export of proteins essential to the bacteria–aphid symbiotic relationship. Although the Buchnera system is clearly a derivative of a more complex flagellar apparatus, it illuminates flagellar evolution by providing an example of what a simpler precursor of today’s flagellum might have looked like – a precursor dedicated solely to protein export rather than motility.
DISCUSSION
The genome analysis of B. aphidicola sp. strain APS has revealed that Buchnera retains flagellar genes coding proteins for the hook and the basal body but not for the filament. The genomic information has also suggested that the partial structure of the flagellum, if it exists, might be used for purposes other than motility to enrich the symbiosis life (15). We report here the first experimental evidence of the flagellar structure existing in Buchnera.
We have found hundreds of HBBs on the cell surface of Buchnera. The HBBs are peritrichously distributed over the surface. Since there are no master genes that control the flagellar number in peritrichously flagellated species such as E. coli and Salmonella, Buchnera flagellar proteins might be constitutively expressed, distributed, and assembled in the membrane without control. Why are so many HBBs necessary for Buchnera? Buchnera is nonmotile, and the flagella lack the essential components of motility such as a filament (the propeller) and the Mot complex (the stator of the motor). These facts suggest that the Buchnera HBBs may have functions distinct from motility. The most plausible function is protein transporter, as the flagellar apparatus belongs to the family of T3SSs.

Of course they are.
Here's such an explanation from cootion: They could have been coopted from other proteins, which were originally different and performed other functions, into a pre-flagellar molecular complex that had another function than to serve as a flagellum.
The actual proteins used in these components could have been recruited from elsewhere, but explaining the actual structures in terms of some stepwise process of exaptation is wishful thinking.
Wortfish wrote:Rumraket wrote:So what? That does not mean it could not have been coopted from other proteins. Nor does it mean it had to first function as a universal joint when it first evolved.
Yes, we know that's what the Darwinist "explanation" is. But it is ridiculous and there is no evidence for this.
Wortfish wrote:Although other components, like the base or the filament, could conceivably have had another use, the hook is acting as a joint between the motor and the propeller. In the absence of either it is useless.
It was Darwin himself who coined the term "evolutionist",
As the dictionary definition states, to be an "evolutionist" is to believe in the principles of evolution by natural selection.

However, the analysis of biological complexity has changed with the application both of genetic procedures that serve to identify the contribution of individual genes to a phenotype and of comparative sequence analyses that can elucidate the evolutionary and functional relationships among genes that occur in all life-forms. As with the evolution of other complex structures and processes (29–32), we have shown the bacterial flagellum too originated from “so simple a beginning,” in this case, a single gene that underwent successive duplications and subsequent diversification during the early evolution of Bacteria.

OP It's fine to be wrong ....seriously degenerate not to admit to it....
You do realize that all this paper tries to show is how the protein parts that make up the flagellum could have evolved. It doesn't actually show how the flagellum, as a structure, evolved by way of natural selection.

Well, Darwinism is more like a cult. Name me one scientific theory where people celebrate the birthday of a scientist as their hero, prophet and saviour? http://darwinday.org/Darwin Day is an organization whose mission is to inspire people throughout the globe to reflect and act on the principles embodied in Charles Darwin.
Now, just change this to.....Christmas Day is an organization whose mission is to inspire people throughout the globe to reflect and act on the principles embodied in Jesus Christ.
No difference. Both are religious leaders.
Celebrating magical fantasies from bronze age goat fuckers is masturbatory, at best.

That pile of shit holds more “information” than the collective efforts of all Intelligent Design proposals to date. This isn’t an insult. This is absolutely factual. If this conclusion offends you are married to your position, and have abandoned the dispassionate prerequisite of basic observation. Because the unsupported presupposition of design influences the investigation everything that follows is self defeating, and tainted. If design is present anywhere in our biosphere it will be found to withstand critical examination to actually be design. This has yet to happen despite the protestations claiming all sorts of reasons why not one peer reviewed publication has been written to date. It’s tripe.
