Creationists often wheel out the bacterial flagellum (a molecular "outboard motor" ) as an example of a structure that could not have evolved. The reasoning being that it is irreducibly complex - take out a component and it is totally useless. Therefore it must have been designed – by their god of course. This of course is an argument from ignorance and limited imagination. Irreducible complexity does not imply a supernatural designer either; sea arches for example are irreducibly complex and produced by entirely natural forces.
This video provides an excellent account of the evolution of the bacterial flagellum and how the intermediate stages are useful in their own right.
Intelligent design has nothing to offer – despite their constant bleating to “teach the controversy”. There is no controversy as this short article highlights.

It would seem this way to me... but some just don't 'get it'
Just watch the video...
All rather clever, but I bet it cannot fly - therefore, God did it
I wonder if it could fly? Would need to stop the bacterium drying out though.
