    “...
    a plant-hopping insect found in gardens across Europe - has hind-leg joints with curved cog-like strips of opposing 'teeth' that intermesh, rotating like mechanical gears to synchronise the animal's legs when it launches into a jump.

    The finding demonstrates that gear mechanisms previously thought to be solely man-made have an evolutionary precedent. Scientists say this is the "first observation of mechanical gearing in a biological structure".

    Perhaps next they will find a bug with gears and wheels?

    I can see creationists jumping on this like a dog on a bone

    My question is, can they find precursors to this form? Maybe somewhere there is a million year old bug in amber.....

    Impossible to evolve!
    What use is one cog?
