From the University of Cambridge

Functioning ‘mechanical gears’ seen in nature for the first time

The juvenile Issus - a plant-hopping insect found in gardens across Europe - has hind-leg joints with curved cog-like strips of opposing ‘teeth’ that intermesh, rotating like mechanical gears to synchronise the animal’s legs when it launches into a jump.

The finding demonstrates that gear mechanisms previously thought to be solely man-made have an evolutionary precedent. Scientists say this is the “first observation of mechanical gearing in a biological structure”.

Cue the idologist stampede ...

Pretty cool! Also just over three years old, and widely discussed at the time.
