Onur Cobanli explains:
Nature create variations of organisms and life-forms and tests them against time. The very best life forms prevails over time due to efficiency, strength and persistence. Designers also follows a similar approach; they initially create a series of designs and their variations which are tested against filters and requirements or restrictions. Those that pass the test, continue to exist. Designers around the world create new products and designs every day that challenge the preexisting designs and ideas.
