Cat123, thanks for posting the paper! It explained a lot of things in details. It seems studying the evolution of these systems is just starting and the paper even suggested lab-based experiments to test possible evolutionary pathways to the current flagellum from simpler components.
So why the evolution of these systems was not studied thoroughly before? According to the paper:
Now, if you can get a PDF to the 2009 paper (Bacterial flagellar diversity and evolution: seek simplicity and distrust it?) that would be awesome!!

Quote:However, the flagellar research community has scarcely begun to consider how these systems have evolved. This neglect probably stems from a reluctance to engage in the ‘armchair speculation’ inherent in building evolutionary models, and from a desire to determine how a system works before wondering how it got to be that way.
