the course of evolution whales and sharks optimized their movements by forming a tail fluke (or tail fin) to propel the animal forward. But the direction of the propelling movements did not matter: a whale’s fluke moves vertically, and a shark’s fin moves horizontally. Either way the goal to propel the animal forward is achieved. (A) To which aspect of optimal feedback control is that related? B) Please give an example of how this can be shown experimentally and elaborate.
