As its ability to echolocate evolved in power, so too did its ability to make longer jumps, which eventually turned into gliding and powered flight.

随着其回声定位能力增强，它也逐渐能够进行更远跳跃，最终演变成了滑翔和主飞行。

Scientists have found that blind people are almost always a little better at echolocating than sighted people.

科学家现，盲人回声定位能力几乎总是比视力正常人要好一些。

And those two adaptations -- stronger echolocation and powered flight -- made bats the stealthy aerial predators of insects that many still are today.

而这两种适应性变化——更强回声定位能力和力飞行能力——使得蝙蝠成为了今天依然存在那些昆虫隐形空中猎手。

Toothed whales developed echolocation, a way to use sound waves to explore their surroundings.

齿鲸了回声定位能力，这是一种利用声波探索周围环境方法。

Did bats evolve flight or echolocation first, or did it evolve in tandem?

蝙蝠是先进化飞行能力还是回声定位能力，或者两者是同时进化？

Scientists think baleen whales lost the ability to use echolocation when they stopped chasing after large fish and other mammals and started eating tiny fish and plankton, which swim in large, slow-moving schools.

科学家认为，当须鲸停止追逐大型鱼类和其他哺乳并开始捕食小鱼和浮游生时，它们就失去了使用回声定位能力，这些小鱼和浮游生成群结队地游缓慢。
