High-speed Gears Discovered in an Insect’s Legs


issus gears When I read about this recent discovery in the Daily Mail, I wanted to change the article’s title to: God Outdoes Engineers Again. The article’s name? “Nature outdoes engineers again: High-speed ‘mechanical gears’ discovered for the first time on the hind legs of a plant hopping insect.” According to the Daily Mail:

Each gear tooth on the insect’s legs has a rounded corner at the point it connects with the other gears to stop teeth from shearing off when they clash, similar to gears on a bike.

The gears on the opposing hind legs lock together like those in in car gear box to make sure the legs are completely synchronised when they move.

God is our Creator and even cares to put gears in a baby bug which coordinates it to jump (within 30 microseconds for each leg).

O Lord, what a variety of things you have made!
In wisdom you have made them all.
The earth is full of your creatures…

They all depend on you to give them food as they need it.
When you supply it, they gather it.
You open your hand to feed them, and they are richly satisfied.
But if you turn away from them, they panic.
When you take away their breath, they die and turn again to dust.
When you give them your breath, life is created, and you renew the face of the earth.
Psalm 104: 24, 27 – 30 (NLT)

NOTES:

  • The juvenile Issus bug uses mechanical gears for precision jumping. The gears are lost in the adult phase of this garden-dweller.
  • A PhD looks at Creation from an engineer’s perspective in this paper given in Seoul, Korea, at the 30th International Seminar on the Integration of Faith and Learning.
