Issus Coleoptratus- Inventor of the Mechanical Gear

The Ancient Greeks Didn’t Invent Everything…

It’s long been thought that the ancient Greeks invented mechanical gears sometime around 300 B.C.E., a fundamental technological advancement that we still use in modern machinery.

But low and behold, the tiny 3mm Issus coleoptratus has been hiding the ingenious toothed gears in their hind legs since the dawn of their existence!

A recent discovery by biologists at the University of Cambridge found that the little bugs have a very intricate gearing system that enables them to propel forward.

This discovery is believed to be the first functional gearing system found in nature. Gears have been found in nature before, but never have they rotated functionally like the ones found in the Issus.

Unbelievable Nature

Without their sophisticated gearing system, the baby Issus would not be able to coordinate a jump. Their legs swing laterally, and without the aid of the gears, they would not be able to synchronize their leg movements to jump straight forward. Instead, they would propel in a haphazard manner and would be unable to articulate a point of landing.

Jumps are for Kids

Even more unbelievable, the gears are only found in a nymph (or juvenile) Issus. As the Issus grows to adulthood, they shed the mechanical gears and grow a whole new mechanism for jumping.
