Peacock-Tailed Dinosaur from China Reshapes Understanding of Bird Evolution

In the ancient badlands of Liaoning, China, a creature barely a foot long has quietly unsettled a century of assumptions about how birds came to fly. Changzhousaurus sinensis, a feathered dinosaur from 120 million years ago, carried peacock-like tail plumes and disproportionately large wings that suggest evolution did not march in a straight line toward flight, but wandered through many experimental forms. Its discovery reminds us that the origin of birds was not a single invention but a long, branching conversation between anatomy and possibility.
