Science ruins everything, right? WRONG! Science makes everything awesome. Fur example, a large percentage (not all) of dinosaurs are now thought to have had feathers. Even the mighty T-Rex:
Stylish, fashionable, warm, and not remotely related to flight. Science thinks, for now, that feathers first evolved for warmth, and later evolved for use in flight. This evolution was carried forward by dinosaurs, who ultimately became birds.
Birds are the evolution of one branch of dinosaurs. All of them. Think of that the next time you feed the ducks.
