"Robot Dinosaur Study Sheds Light on Evolution of Wings and Plumage"
Scientists used a robotic dinosaur to study the evolution of wings and proposed that small feathered dinosaurs might have flapped early wings to flush out insect prey, providing an explanation for why wings evolved before flight. The research, published in the journal Scientific Reports, adds to the puzzle of why wings developed in the age of dinosaurs and suggests that wing displays may have served multiple purposes, including hunting and frightening hiding prey.
