10 Animals That Can Do Things Humans Absolutely Can’t

9. The Gecko: Gravity-Defying Climbers

Geckos are known for their incredible climbing abilities, effortlessly scaling vertical surfaces and even walking upside down. This gravity-defying feat is made possible by the unique structure of their toe pads, which are covered in millions of tiny hair-like structures called setae. These setae use van der Waals forces—which are weak intermolecular attractions—to adhere to surfaces without the use of liquids or suction. The gecko's climbing prowess has inspired the development of advanced adhesives and robotic technologies that mimic its natural abilities. This remarkable adaptation demonstrates the ingenuity of evolution in solving complex physical challenges and highlights the potential for biomimicry in our efforts towards advance engineering and design.
