In findings published on Thursday in , scientists from China's and the reported bird flight may have evolved from wing-flapping by running dinosaurs. These findings support the hypothesis flight could have evolved up from the ground, in contrast to models in which active flapping flight evolved after gliding, a passive form of flight. Artist's reconstruction of  . The authors proposed that in Caudipteryx , from a mechanical perspective, two-legged running automatically induced wing flapping. The authors of the report used a mathematical model, a robot, and young ostriches to test their hypotheses.
