The Gecko - A Product of Evolution or Creation?
They walk across walls and ceiling as though gravity didn't exist. But how? For a long while, geckos defied all attempts to explain how they could cling to any surface with no visible sign of glue or suction cups. Then, when a group of biologists and engineers studied the microscopic hairs on the toes of geckos, the answer was found. The ends of the hairs directly attach to molecules in the surface by what is called van der Waals force, a type of attraction between atoms. According to a report in Nature, scientists concluded that engineering a structure like the foot of a gecko is "beyond the limits of human technology." However, they hope that the "natural technology of gecko foot-hairs can provide biological inspiration for future design of a remarkable effective adhesive."
