Biomimetics (as described in Wikipedia) is the imitation of the models, systems, and elements of nature for the purpose of solving complex human problems. Over the last 3.6 billion years, nature has gone through a process of trial and error to refine the living organisms, processes, and materials. The emerging field of biomimetics has given rise to new technologies created from biologically inspired engineering at both the macro scale and nanoscale levels.  Humans have been looking at nature for answers to both complex and simple problems throughout our existence. Nature has solved many of today's engineering problems such as self-healing abilities, environmental exposure tolerance and resistance, hydrophobicity, self-assembly, and harnessing solar energy through the evolutionary mechanics of selective advantages.
