Evolution is a race. A survival of the fittest. And because of this, nature has come up with some incredible answers to our planet’s difficult questions. Animals’ exoskeletons, which make them strong, protected from predators and mobile, now provide inspiration for scientists hoping to aid disabled people to walk. The cuttlefish’s ability to camouflage itself in almost any marine environment has lead to the development of specialist camouflage technology for the military. And even an owl’s wing is now being used to make our world a tiny bit quieter. Fan companies are studying their ability to fly silently and copy this for their product’s fan blades. The race to be stronger, better, quieter, faster has given us answers from nature that we can copy to advance ourselves.
