Should you teach that the bacterial flagellum evolved? . . . Since by all evidence it did, yes.

Did you read your links? They don't really offer evidence. It's mostly speculation. For instance:

A possible scenario for the evolution of the eubacterial flagella is as follows: a secretory system arose first, based around the SMC rod pore forming complex, which was the common ancestor of the type III secretory system, and the flagellar system.

The proto-flagellar filament arose next as part of the protein secretion structure (cf the Pseudomonas pilus, the Salmonella filamentous apendages and the E coli filamentous structures), finally (as suggested by the presence of at least two, if not three, indpendent motors) an ion pump which was doing something else [see note] became associated with this structure and motility (presumably weak) occured fortuitosly. Even today MotAB can freely dissociate and re-associate with the flagellar structure. This early, limited motility was later refined into the more compentent system we see today. Alternatively, the ion pumps became linked to the proto-flagella to provide extra "power" to pump proteins out of the complex, and flagella motion occured via fortuitous mutations in the linkers Fli G,N,M later on. Regulation and switching can be added on later as there are modern eubacteria that lack these and function well in their environments.

Do you really think that is science?

Miller's piece is more of a diatribe than a debunking. Because the flagellum has some proteins homologous to the TTSS how does that show the evolution of the flagellum or disprove IC? Where did the propeller come from?

Talkorigins, of course, is not a science site & should not be taken seriously.

Coming up with viable hypotheses? You bet. Or did you think science was doen by Laws and Theorems beign handed to men by God ona silver platter?

OK. Then please point to a science site that backs up the notion that God said ZAP and suddenly bacteria had flagella.

I'll wait.
