A Unified Theory of Animal Locomotion

Roland Piquepaille writes "You probably already know that there is a master equation for all life processes based on metabolism. Now, physicists from Duke University have applied the so-called 'constructal theory' to explain how running, flying and swimming modes of locomotion are similar even if they're apparently unrelated. This single unifying physics theory explains how fast animals get from one place to another and how rapidly and forcefully they step, flap or paddle in relation to their mass. In other words, these scientists argue that the characteristics of animal shape and locomotion are predictable from physics."

    I wonder who could expected the outcome to be the other way around.

    Yes, they are the same or different. I could have told you that without a research paper.

    Forget the penguin for a moment.

    Are birds buoyant in their fluid?
    That right there is a big difference.

    Robotics researchers already knew that something like 'animal' locomotion could be implemented based on the principles of physics. ie. given the right mechanical setup, locomotion is almost automatic and takes no supervision by a computer.

    Actually, it's what you'd expect. Animals would naturally evolve to move in an efficient manner. It would give them an evolutionary advantage. What the bleep did these guys expect?

    You have obviously never hooked a bird up to a tank of hydrogen. I assure you, they're quite buoyant before they explode.

    Well if they're fast animals, and they're going from one place to another, perhaps they do it by moving quickly? Ever considered that?

    If such methods are better, why has no animal evolved them?


    It could be just "bad luck" -- evolution isn't guaranteed to find the best solution to anything, only a solution that is "good enough" to guarantee survival of the species (otherwise the species would have gone extinct). But putting that aside, there are probably structural reasons why animals never evolved wheels -- for example, how would do you connect nerves or blood vessels to an appendage that needs to be able to rotate freely?


    Finally, it could be that in nature wheels aren't actually "better" after all. There wouldn't be much use in being able to roll down a freeway at 50MPH if there are no freeways, and your snazzy evolved bio-wheels keep getting stuck in the mud...
