纪录片《侏罗纪之谜》 第14期 恐龙的进化

（单词翻译）

When they looked further, there were clear signs that the fish had been killed by a volcanic¹ eruption²,

他们继续搜寻后发现，一些显著迹象表明这些鱼的确死于火山爆发

but then the evidence became more confusing.

可是后来的证据开始变得模棱两可

When Oliver's team looked on land they found nothing,

当Oliver的小组研究陆地状况时，他们一无所获

no sign of an extinction³ event affecting the dinosaurs⁵.

没有证据表明灭绝事件影响了恐龙

Whatever had killed the fish and caused the mass extinction in the oceans, it hadn't affected⁶ life on land.

不管是什么杀死了鱼，并导致海洋中的大灭绝，它并没有影响到陆地生物

That meant dinosaur⁴ evolution couldn't have been kick-started by a mass extinction. That theory was wrong.

也就是说恐龙的进化并非由大灭绝引爆，这种假设是错误的

It meant scientists would have to find something else,

这意味着科学家们必须找出其它原因

something equally connected to the break-up of the super-continent

超大陆的分裂还关系到另一事件

and powerful enough to have transformed the evolution of the dinosaurs,

它的强大作用也足以改变恐龙的进化历程

so they turned to another theory: climate change.

因此他们开始关注另一种观点：气候变化。
