Scientists believe that it could glide from tree to tree like a flying squirrel, rather than the flapping flight used by birds.

科学家们认为，这种恐龙能同飞鼠一样在树间滑翔，而不是像鸟类那样振翅飞翔。

But unlike modern birds, Microraptor had not yet evolved the specialized shoulder anatomy for powered, flapping flight.

但与现代鸟类不同的是，小盗龙尚未进化出用于动力扑翼飞行的专门肩部解剖结构。

He's convinced that the powered, flapping flight of modern birds really did begin on the ground with a running start.

他坚信，现代鸟类的动力扑翼飞行确实是从地面开始的。

Over time, the feathers could have been adapted for flight, as bodies became smaller and the running leaps of dinosaurs evolved into the powered flapping flight of birds.

随着时间的推移，羽毛可能已经适应了飞行，因为身体变得更小，恐龙的奔跑跳跃演变成鸟类的动力扑翼飞行。
