Flagellum gives bacteria a sense of touch. Behe is right. | Uncommon Descent

“…Irreducible complexity. From ScienceDaily:

Although bacteria have no sensory organs in the classical sense, they are still masters in perceiving their environment.

Swimming Caulobacter bacteria have a rotating motor in their cell envelope with a long protrusion, the flagellum. The rotation of the flagellum enables the bacteria to move in liquids. Much to the surprise of the researchers, the rotor is also used as a mechano-sensing organ. Motor rotation is powered by proton flow into the cell via ion channels. When swimming cells touch surfaces, the motor is disturbed and the proton flux interrupted…”
