A Five hundred million different species of living creatures have appeared on Earth, nearly 99 percent of them vanishing.  vanishing修饰appearance of species,修饰错。

B Nearly 99 percent of five hundred million different species of living creatures that appeared on Earth have vanished.
从过去到现在出现的物种消失了，appear应该用完成时

C Vanished are nearly 99 percent of the five hundred million different species of living creatures that appeared on Earth.
句子一读就别扭：被消失的是一大串什么东西
D Of five hundred million different species of living creatures that have appeared on Earth, nearly 99 percent of them have vanished.
E Of the five hundred million different species of living creatures that have appeared on Earth, nearly 99 percent have vanished.
DE：首先the可有可无，曼哈顿里的人也是这么说的，有和没有差别不大。
E还原：nearly 99 percent of the five hundred...have vanished.
然而D还原：nearly 99 percent of them of the the five hundred...have vanished.重复，D真正错在这。

这个题作者不应该纠结在A选项吧，这是两个分句子组成的句子，逗号前后都应该是完整的两个句子，用vanishing明显就不是谓语，所以A肯定错。
