Quick Answer
Flight feathers likely evolved in theropod dinosaurs during the Jurassic period, over 150 million years ago.
The Full Story
The exact origin of flight feathers is debated, but evidence suggests they evolved before birds fully learned to fly. Jurassic fossils show feathers with asymmetrical shapes associated with aerodynamic function. These feathers probably first helped with display, insulation, or balance before being used for powered flight. By the time early birds appeared, feathers were already highly specialized.
