"Maybe; if it knew where it was steering to!"
Apparently, it had some primitive senses about that. Ian Musgrave mentioned that one species used Brownian Motion to adjust its heading, before activating its motor again.
In Rhodobacter sphaeroides, the genes equivalent to MotA and MotB have only 19% sequence identity, so it is not clear if these proteins are divergent modifcations of the ancestral MotA MotB or convergent evolution of an unrelated motor(11,13). The Rhodbacter motor doesn't switch as does the other motors, but turns on and off, and re-orientation is via brownian motionIt's an interesting article, not very long, and fairly understandable.
That would be a neat trick; considering that BM is RANDOM!
