Functioning 'Mechanical Gears' Seen In Nature For The First Time


Once thought as man-made, gear mechanisms have been discovered in nature for the first time. 



Functioning as leg hinges of a plant-hopping insect found in gardens across much of Europe. Issus is the genus of plant hoppers where the dog-like joints were discovered. 




The gears do serve quite a powerful purpose as the bug can jump at high distances and speed, producing between 500G and 700G of force.

The gears are in synchronicity in back leg movement, which a nervous system could not do so.

“This precise synchronisation would be impossible to achieve through a nervous system, as neural impulses would take far too long for the extraordinarily tight coordination required,” says Professor Malcolm Burrows, lead author, from Cambridge’s Department of Zoology.

“By developing mechanical gears, the Issus can just send nerve signals to its muscles to produce roughly the same amount of force – then if one leg starts to propel the jump the gears will interlock, creating absolute synchronicity."

"So, we thought we created the gear mechanism, but it seems that we actually discovered it. What other inventions already exist in nature?”
