"Nature has had more time than we have had. There are around 1,450 species of geckos, and around 40 per cent have non-stick feet. Thanks to this study, we now know that the geckos are a superb example of convergent evolution, where different groups of animals independently hit upon the same traits as solutions to the same challenges.

Gecko toes are well-studied and their sticky properties have inspired some incredible technology, such as stitch-free ways to seal wounds and sticky handheld paddles that may help soldiers scale walls someday. Geckos are renowned for the sticky feet that enable them to climb a variety of surfaces. Moreover, making and breaking the bonds that hold individual setae to a surface is easy. Baio, C. Jaye, D.A.

Each seta splits off into hundreds of even smaller bristles called spatulae. Gecko toes are covered in tiny ridges, which are themselves covered in really tiny hairs, called setae. These little critters found their way to the world between 180 and 225 million years ago. The analysis revealed that the alignment of the keratin fibers is in the direction of the setae, which might be how they resist abrasion. These animals can sniff it out. This tropical lizard runs up walls and upside down across ceilings as readily as across floors. The gray squiggles represent lipid molecules. Setae are also ultraflexible.
