地球上还有活恐龙吗?

Are dinosaurs still alive today?

现在还有活恐龙吗?
Are dinosaurs still alive today?
美国自然历史博物馆《迪诺思零距离》
.
令人诧异的回答是 恐龙还活着
The remarkable answer is that dinosaurs are still alive,
但不需要到某些人迹罕至的岛上去找
but you don’t need to go looking for them on some deserted island.
恐龙其实就在我们周围
They’re actually all around us,
因为所有鸟类都是恐龙
because all birds are dinosaurs.
鸟类不仅仅从恐龙演变而来
Not only did birds evolve from dinosaurs,
科学地讲鸟类就是恐龙
scientifically they are dinosaurs,
就好比我们人类是灵长类
just like how us humans are primates.
6600万年前小行星撞地球
Sixty-six million years ago an asteroid impact
造成恐龙大批死亡
did kill off a lot of the dinosaurs,
但其中一支幸存下来
But one lineage survived,
它们就是所有现代鸟类的祖先
and those are the ancestorsof all modern birds.
目前为止 古生物学家尚未发现
To this date paleontologists have never found a non-bird dinosaur
从大灭绝事件中存活的非鸟类恐龙
that was alive after the extinction event.
即使发现了
Even if we did,
这种激动人心的事 不可能不公之于众
we’d be too excited to keep it to ourselves.
既然知道了鸟类是恐龙
Now that we know birds are dinosaurs,
你们有些人可能会失望
some of you may be disappointed that
今天还活着的恐龙看上去
modern dinosaurs that are alive today
和中生代时期的恐龙并不像
don’t really look like the dinosaurs from the Mesozoic Era.
但是新研究表明恐龙有许多
But new research is finding that dinosaurs had a lot of
现代鸟类也具备的重要特征
the important features we associate with birds today.
比如 我们知道
For example, we now know that
很多种恐龙长有羽毛
many of the dinosaur groups had feathers,
或是称为原始羽毛的羽毛前身
or precursors to feathers we call protofeathers.
因为这些恐龙无疑不会飞
Because these dinosaurs clearly didn’t fly,
我们认为最初演变的羽毛
we think that feathers first evolved
是用于调节体温和炫耀行为的
for regulating body heat or for display.
-我真好看 -随便你
.
和鸟类一样 恐龙已经有了高水平新陈代谢
Dinosaurs, like birds, already had high metabolisms,
减轻重量的中空骨 叉骨
hollow bones that made them lighter, wishbones,
以及对体型来说相对较大的大脑
and also relatively large brains for their body size.
所以总的来说 恐龙可能和鸟类非常像
So collectively, dinosaurs may have looked a lot like birds.
如果你穿越到中生代的环境
And if you were dropped off in an environment in the Mesozoic era,
你可能会错把某些恐龙当成火鸡
you might actually mistake some of the dinosaurs for turkeys.
[火鸡咯咯叫]
Gobble Gobble
所以下次看到低调的鸽子
So the next time you see a humble pigeon,
要记得它们其实是从6600万年前的
just remember the fact that they’re part of a very successful lineage
大灭绝中幸存下来的成功世系
that survived the mass extinction event 66 million years ago
这场大灭绝杀死了所有其他种类的恐龙
that wiped off all the other dinosaur groups.
