Continue reading North American Birds have Disappeared in Droves
How did dinosaurs learn to fly? Robots can help model the flapping wings.
Scientists generally agree that today’s birds descend from ancient flying dinosaurs, but nobody is sure exactly how the first flying dinosaurs actually took flight. 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.
