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

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

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”.

  1. I’d be keen to see an analysis of the geometry to see if it is more effective then humane designed gearing

  2. Looks like a great design.
