This then enabled the rise of carnivores, which in turn spurred a productive arms race, resulting in what's known as the Cambrian explosion.

Unconformities are places where rocks have been eroded before new ones are deposited, and the widespread Ediacaran-Cambrian unconformity has been a big obstacle to understanding the Cambrian explosion.

不整合面地方的石块在新的沉积之前已经被侵蚀，埃迪卡拉纪-寒武纪之间广泛的不整合面是了解寒武纪大爆发的一个重大障碍。

In fact, the record as it existed then (and for a long time afterward) showed no life at all right up to the moment of the famous Cambrian explosion.

其实，当时（及以后很多年）已发现的化石表明，一直到著名的寒武纪大爆发之前，地球上根本没有任何生命。

There, 8,000 feet above sea level, he found a shale outcrop, about the length of a city block, containing an unrivaled array of fossils from soon after the moment when complex life burst forth in dazzling profusion-the famous Cambrian explosion.

在海拔2438米的地方。他发现了一个页岩露头，长度大约相当于城市的一个街区，里面蕴藏着一大批化石，远自复杂生命大爆爱——即著名的寒武纪大爆发——之后不久的时候。

There's another feature of all of this that I've lived in my lifetime, I'm 83.I was born in 1939.Just like the Cambrian explosion, watch the number of things that have come into existencein my lifetime.
