From basic levers to more advanced mechanical devices like pumps, nature beat us by a long mile when it comes to 'inventing' engineering feats.
dates back to ancient times, with early examples of threaded fasteners found around the 5th century B.C. These early fasteners were made of wood and were used in architecture and machinery.
Metal nuts and bolts appeared in the 1st century A.D. in Roman structures, and the use of screws increased during the Renaissance. The Industrial Revolution led to the standardization and mass production of nuts and bolts, making them essential components in machinery, construction, and transportation. As secure and reliable fastening solutions, nuts and bolts are critical in various industries, from aerospace to automotive.
Researchers have discovered that weevils, specifically the Trigonopterus genus, use a nut and bolt mechanism to attach their legs to their bodies. This unique joint, previously thought to be of a hinge type, was found in thewhere the top section of the weevil's legs, the trochanter, screws into the coxa, akin to a hip.
In nature, hooks are a pretty common physical structure, with many plants, such as cockleburs, having hook-like structures that attach to passing animals, facilitating seed dispersal. Interestingly, this particular design
