The Only Mechanical Gears Ever Found in Nature

with 2 comments

Above is a photo of the gear “mechanism” (only it’s not a mechanism, but a natural adaptation) used by the small hopping insect Issus coleoptratus to precisely synchronize the kicks of its hind legs as it jumps forward.

Interesting, due to tooth fragility, the gears are dropped as the insect matures (by molting). Full report in this Smithsonian article.

  2. It is neat. I doubt we’ll ever see a wheel-and-axle occur through evolution, though. Levers we see aplenty — the grasshopper is obvious, but our own muscular-skeletal system is full of them, along with ball-and-socket joints.
