When I was a kid, I would dream of being able to climb up walls and crawl across the ceiling. When someone would come into the room I would jump down from the ceiling and scare the dickens out of them. A few years later, I would sneak out at night with a flashlight and watch the geckos running across the outside of the house and up the block fence. I would often wonder what it would be like to be able to climb up walls and even mountains like the geckos did.
Little did I know that years later those same little geckos would be the subject of me Master’s degree research. During my research, I had up to 100 geckos in glass tanks that filled my study at home. One of the biggest problems I had was keeping the geckos from escaping from the tanks whenever I took the lid off to feed, water and clean them. The geckos had no problem climbing up the sides of the glass tanks and making their way to freedom. I soon found it necessary to apply a thin layer of cooking oil along the upper edges of the tank to keep the geckos from being able to grip the glass and escaping.
Have you ever watched a gecko climb a wall or run across the ceiling? Today we are going to learn just how they are able to do it.
When scientists started looking at the gecko’s feet under the microscope, they discovered that the toes are covered by millions of microscopic hairs called setae. At the end of each setae there are from 400 to 1000 branches, each of which end in a tiny flattened spatula like structure. These flattened ends are less than 1/50,000 of an inch in size.
Amazing as the geckos foot is, what good is it to have all of these microscopic hairs that allows the gecko’s feet to stick to walls and glass, if it can’t unstuck itself from the walls? Further study showed that the geckos uncurl their toes when they want them to stick to a wall or glass and then peel them off the wall by curling them back up again. What’s more, the gecko can curl and uncurl their toes as fast as needed to allow them to run at full speed across the ceiling or along a wall.
A number of scientists have been working on trying to duplicate the gecko’s amazing feet in hopes of developing some kind of shoes and gloves that would allow people to climb up walls like a gecko or Spiderman. Think of all the things these special shoes and gloves could be used for. It would make rescuing people trapped in high rise buildings easier when ladders can’t reach them. Window washers and high rise construction workers could also benefit from having these tools. Scientists have admitted that their structure is beyond the limits of human technology. However, no one has yet been able to duplicate the marvelously designed gripping feet of the gecko.
Now I want to ask you how do you think all of these microscopic setae each with nearly a 1000 branches ending in a spatula shaped structure could have evolved? If they evolved slowly as most evolutionists believe, what purpose would a partially evolved setae have to the gecko before they became fully functional? Then realize that the gecko would have to have known when to curl and uncurl his toes to make it all work.
There really isn’t a good evolutionary explanation for the amazing gecko’s complex toes and its ability to crawl up walls and walk across ceilings. The only explanation that makes any sense is to realize that when God created all of the land animals, including those animals that creep along the ground, on Day 6 of Creation, that He gave the geckos their special toes and natural ability to use them. He truly is an amazing Creator God.
