What is the significance of the newly discovered fossils?

Chinese scientists have discovered fossils of a feathered, four-winged dinosaur, which they say give new clues to the origins of flight. The creature lived about one hundred and twenty-five million years ago and was less than a meter long. The creature couldn’t actually fly but would have used its four wings and long feathery tail to help it glide from tree to tree as flying squirrels do today. It’s relative of the dinosaur Micro-Raptor. The discovery could change ideas about how birds evolved. Most experts thought they came from dinosaurs that lived on the ground and developed feathery limbs, which they flapped so they could run faster. But this latest find supports an alternative theory that birds evolved from animals that lived in trees. This was first suggested around 1915, but there’s been little evidence to support it until now.
