Nature leads the way again for science
Science is constantly looking to the natural world for clues on how to built the better machine. The flight of the butterfly is paving the way for tiny aerial machines . The erratic looking flight of the butterfly, on closer examination, is a total mastery of the air, where the insect can use 6 different sorts motions of the wings to stay aloft, changing as needed from wingflap to wingflap. It was compared to the way a horse can change gait effortlessly.
The beautiful brittle star isn't where most people would look to for superior eyesight, but they are literally covered with perfect lenses, allowing for a total wrap around view. The lenses are much better than what we can make, thanks to the perfect use of chalk-like calcite crystals in its skeleton.
