Or you could have motors :-)
I saw a doco a few years back on the systematic breaking down of the intelligent design arguments re certain things found in nature.
( Based on a US school court case )
One was Bacterial Flagellum.
The ID people said it could only have been made/designed by "an entity"
but researchers found several variants which appeared to show there was evolution down several different paths.
Not interested in those arguments either way,
but as a micro motor made by nature, its an astounding bit of work.
