Will zoologists ever know the evolutionary sequences in the Cambrian explosion?
动物学家们是否知道寒武纪大爆发中动物的进化顺序呢？

To be born during this, the Cambrian Explosion—why, I couldn't imagine a better period, really.
在寒武纪生物大爆发这时候降生-我实在没法设想一个更好的时代了，真的。
Will zoologists ever know the evolutionary sequences in the Cambrian explosion?
动物学家们是否知道寒武纪大爆发中动物的进化顺序呢？
来源于：阅读OFFICIAL5 P3The Cambrian explosion involved rapid evolutionary diversification, followed by the extinction of many unique animals.
寒武纪大爆涉及到了快速的进化分化，接着就是很多独特动物的灭绝。
来源于：阅读OFFICIAL5 P3A third fossil formation containing both soft-bodied and hard-bodied animals provides evidence of the result of the Cambrian explosion.
第三种化石层既包含了软体动物也包含了硬体动物，它为寒武纪大爆发提供了证据。
来源于：阅读OFFICIAL5 P3At one time, the animals present in these fossil beds were assigned to various modern animal groups, but most paleontologists now agree that all Tommotian fossils represent unique body forms that arose in the early Cambrian period and disappeared before the end of the period, leaving no descendants in modern animal groups.
在一段时间内，人们认为这些化石中的动物分化出了各种各样的现代动物。但是古生物学家们现在却认为，所有的Tommotian化石都仅代表在寒武纪初期出现但到寒武纪结束时就消失了的特别生物。所以它们没有在现在动物中留下后代。
来源于：阅读OFFICIAL5 P3It dates to the very early Cambrian period, and it also contains only soft-bodied forms.
它形成于寒武纪的早期，并且同样只含有软体动物化石。
来源于：阅读OFFICIAL5 P3This rapid origin and diversification of animals is often referred to as “the Cambrian explosion.”
这次快速的动物起源和分化常常被称为“寒武纪大爆发”。
来源于：阅读OFFICIAL5 P3Limestone may be found in the Cambrian or—300 million years later—in the Jurassic strata, but a trilobite—the ubiquitous marine arthropod that had its birth in the Cambrian—will never be found in Jurassic strata, nor a dinosaur in the Cambrian.
人类有可能在侏罗纪时期的地层中发现寒世纪或者3亿年后的石灰岩，但绝不可能在侏罗纪时期地层中发现三叶虫化石（三叶虫是寒武纪非常普遍的水生节肢动物），也不可能发现寒武纪时期的恐龙化石。
来源于：阅读OFFICIAL6 P2Quartz is quartz—a silicon ion surrounded by four oxygen ions—there’s no difference at all between two-million-year-old Pleistocene quartz and Cambrian quartz created over 500 million years ago.
石英是石英 - 被四个氧离子包围的硅离子 - 在5亿年前创造的200万年前的更新世石英和寒武纪石英之间没有任何差别。
来源于：阅读OFFICIAL6 P2Since the Cambrian period, biodiversity has generally risen, but there have been some notable exceptions.
自从寒武纪，生物开始变得多样化，但是也有些例外。
来源于：阅读OFFICIAL33 P3It was not until the Cambrian period, beginning about 600 million years ago, that a great proliferation of macroscopic species occurred on Earth and produced a fossil record that allows us to track the rise and fall of biodiversity.
直到六亿年前的寒武纪，肉眼可看的物种才在地球上兴起。多亏了化石的帮助，我们现在可以了解到物种的兴衰。

Sprigg was excited by both the unusual appearance of the fossils and by their age, which he believed to be the beginning of the Cambrian, and made them the oldest animal forms yet seen.
斯普里格感到十分兴奋，因为化石外观很不寻常，并且他相信化石上的生物属于寒武纪起始的那段时期，这样一来，化石上的生物便是当时发现的最古老的动物物种了。
Limestone may be found in the Cambrian or—300 million years later—in the Jurassic strata, but a trilobite—the ubiquitous marine arthropod that had its birth in the Cambrian—will never be found in Jurassic strata, nor a dinosaur in the Cambrian.
人类有可能在侏罗纪时期的地层中发现寒世纪或者3亿年后的石灰岩，但绝不可能在侏罗纪时期地层中发现三叶虫化石（三叶虫是寒武纪非常普遍的水生节肢动物），也不可能发现寒武纪时期的恐龙化石。
