But basically, you know, the 90s and internet feels like a pre-Cambrian era when there were only sponges.

In the context of the Cambrian, explosion would soon have more to do with modern tempers than ancient physiological facts.

联系到寒武纪氛围，“爆发”很快跟现代人脾气，而不是跟古代生理上事实更有关系。

In fact, says Fortey, there are relatively few Cambrian designs that are wholly novel.

实际上，福泰说：“寒武纪造型只有几种是完全新。

Well, we have the Machinchang Cambrian Geoforest Park, the Killam Karst Geoforest Park, and the Dayang Bunting Marble Geoforest Park.

那么这三个公园是哪些呢？它们分别是马珍昌寒武纪地质森林公园、基廉喀斯特地质森林公园和达扬本丁大理石地质森林公园。很好。

But red in tooth and claw the Precambrian was not—for neither teeth nor claws existed.

但是前寒武纪时期却不是腥牙血爪，因为那个时候牙齿和爪子都没有出现。
