PASSAGE
The Wright brothers did not have to look far for ideas when building their airplane, they studied birds. The act of copying from nature to address a design problem is not new, but over the last decade the practice has moved from obscure scientific journals to the mainstream. The term ‘biomimicry’, popularized by American natural-sciences writer Janine Benyus in the late 1990s, refers to innovation that take their inspiration from flora and fauna. Biomimicry advocates argue that with 3.8 billion years of research and development, evolution has already solved many of the challenges humans now encounter. Although we often see nature as something we mine for resources, biomimicry views nature as a mentor. From all around the globe, there are countless instances where natural sources have served as inspiration for inventions that promise to transform every sector of society. One such instance occurred in 1941 when Swiss engineer, George de Mestral was out hunting with his dog one day when he noticed sticky burrs, with their hundreds tiny hooks, had attached themselves to his pants and his dog’s fur. These were his inspiration for Velcro.
