How and why do people copy animals‪?‬

People have learned a lot from animals and copied many of their ways of surviving. This interesting book details many, often surprising, examples: bird flight and airplanes; defensive equipment such as helmets and turtle shells; strong spiderlike threads for surgeries; heating and cooling systems such as those created by termites; camouflage patterns on uniforms or vehicles in battle; and animal prints copied in fashions and decorations.
