Gears may seem like a purely human invention. And yet the basic interlocking mechanism found inside grandfather clocks and car steering systems has now turned up in the remarkably powerful legs of young planthopper insects. The discovery, published in Friday's edition of the journal Science, provides the first known example of working gears that evolved in a living being.

Microraptor , a small dinosaur that lived in northeast China about 120 million years ago, had feathers on its wings, hind legs and tail. But in all likelihood, it didn't fly like a bird.
