In this large family, which dinosaur evolved and flew into the sky? How did you know?

Some predatory dinosaurs gradually became smaller and more like birds, with hollow bones, enlarged brains, light bodies, agile movements, longer and longer forelimbs that could flap like bird wings, and feathers growing on their bodies. No scales or armor. Some went to trees to survive in order to avoid enemies or find food. They jumped and landed on trees, gained the ability to glide, and later were able to fly. The feathered Konglong ran on the ground and learned to fly. So a dinosaur evolved into a bird and flew into the blue sky.
