About this episode
For years, scientists debated whether the first flying dinosaurs, the ancestors of modern birds, began by running and making little hops off the ground, or leapt off a tree branch to glide. It’s called the “ground up vs. trees down” debate, for short. But a newer perspective on this mystery suggests that flying dinosaurs tried taking flight from more than one place. Recent findings suggest that the ability to fly could have evolved not just once but three separate times among dinosaurs.
