Mother nature invented the gear

Humans came up with the invention of the gear in mechanics, but it seems at least one insect beat them to it.

The appropriately-named planthopper uses gears in its hind legs to leap on a level Superman might be amazed to see. An article posted September 12 in the Health & Science section of the Washington Post website notes the planethopper uses its “hind legs that mesh and rotate to synchronize the timing of each limb’s release during a jump.”

Amazing stuff.
