In 2002, the fossil of a four-winged dinosaur was discovered in China and named a microraptor. What was the significance of the discovery? It supported the idea that flight evolved from the ground up. It allowed scientists to reach a conclusion about the origin of flight. It enabled scientists to develop theories about the origin of flight. It provided clues for scientists to develop a hypothesis about the origin of flight.
The feathered limbs are thought to be a “four-winged” gliding characteristic of the Microraptor. Given that the feathers were used for gliding instead of flying, this supports the theory that flight began in the trees and not on land. If so, this finding will be seen as a very important stage in the evolution of flight for a bird.
