Some weeks ago I had the pleasure to attend to a special seminar about Senses, Sources and Evolution.
One of the lectures was about Biomimicry, which is the science and art of emulating Nature's best biological ideas in order to solve human problems. The Biomimicry Institute has a very clear website about their researches; you must have a look at it.
The lecture was a very inspiring moment, there is so much that the industry has already "copied" from nature, like how does nature create self cleaning surfaces? how does nature keep heat and cool a home? you can find even more answers to your questions on the AskNature website.
