A group of researchers from Tsinghua University and the Chinese Academy of Sciences think they might be able to piece together the origins of flight using a mix of fossils, mathematical models, robotic models, and modern ostriches. The scientists started their … Continue reading How did dinosaurs learn to fly? Robots can help model the flapping wings.
