Here on Creation Moments we have often mentioned the gecko’s amazing ability to walk up, or even upside down, on surfaces as smooth as glass. We have pointed out that the gecko can grip even a glass surface as it walks with microscopic hairs on its feet. These minute hairs actually grip the surface at the molecular level.
Noting that geckos never seem to clean their feet, scientists wondered what would happen if the microscopic hairs became fouled with microscopic dust particles. They computed that particles would have to foul between 26 and 59 hairs on each foot to be effective. They then fouled geckos’ feet with micro-spheres and observed them as they walked on a glass surface. To their surprise, with each step the geckos’ grip on the glass surface became stronger. This result suggested that with each step, the geckos’ feet were shedding some of the micro-spheres. To determine if this was what was happening, scientists removed some of the fibers from gecko feet and studied their interaction with the micro-spheres. Their conclusion was that gecko feet are indeed self-cleaning.
Not only is the design of the gecko’s feet amazing, but God evidently realized that His design would not work unless it was self-cleaning and able to shed dust. This design certainly cannot be attributed to a hit or miss process like evolution.
