Snakes pick up ground vibrations by way of their jawbones, which connect directly to their middle ear bones.

蛇通过下颚骨接收地面振动，而下颚骨直接连接到它们的中耳骨。

And they get picked up by other baleen whales, possibly via their skulls, which conduct the vibrations along to their ear bones.

其他须鲸能接收到这些声音，可能是通过它们的头骨，并将振动传导到耳骨。

No ear holes, no ear drums, and no inner ear bone that other reptiles have.

没有耳孔，没有耳膜，也没有其他爬行动物所具有的内耳骨。

They went from scaly, lizard-like creatures like Ophiacodon to fully warm-blooded, furry creatures with mammalian jaws and middle ear bones.

它们从像 Ophiacodon 这样的有鳞、类似蜥蜴的生物发展为完全温血、毛茸茸的生物，具有哺乳动物的下颚和中耳​​骨。

Frantz and his colleagues analyzed the DNA from a 4,800-year-old Irish dog's ear bone, along with the genomes of hundreds of other modern and ancient dogs.

弗朗茨和他的同事们对4800年前爱尔兰狗的耳骨及数千只现代及古代狗的基因组进行了对比分析。

Instead, what was once their ear bone became fused to their jaw, where it allows snakes to detect vibrations in the ground.

取而代之的是， 曾经是它们的耳骨的部分与它们的下巴融合在一起，这让蛇能够检测到地面的振动。

Rittmaster's collection is one of the most thorough in the state. He has whale teeth, an ear bone from a baby dolphin, and even ribs from a humpback whale.

全国来讲，瑞迪马斯特的收藏非常丰富。他藏有鲸鱼的牙齿，海豚宝宝耳骨，甚至还有座头鲸的肋骨。

But, it turned out that this tiny mammal had a specialized, thickened ear bone that, until this discovery, has only been found in whales.

但是，事实证明，这种小型哺乳动物有一种特化的、加厚的耳骨，在这一发现之前，这种耳骨只在鲸鱼身上发现过。

Lots of different features also help animal ears hit especially high notes, like the extra hard, stiff middle ear bones of toothed whales; like dolphins and sperm whales, which efficiently propagate high-frequency vibrations.

许多不同的特征也有助于动物的耳朵捕捉特别高的音调，比如齿鲸的中耳骨特别坚硬，像海豚和抹香鲸一样，能有效地传导高频振动。

And Namib Desert golden moles regularly stick their heads into the sand, which likely helps them use their large, club-like middle ear bones to sense low-frequency activity in mounds more than 20 meters away.

纳米布沙漠金色鼹鼠经常把头插进沙子里，这很可能有助于它们利用大如棍棒的中耳骨来感知 20 多米外土丘上的低频活动。
