逗号doing结构应当表示伴随或者立刻发生的结果，在这里既不是伴随关系也不是立刻发生的因果关系，不可以这么用。

句子重點應該在消失，而不是出現過幾種物種

in the original, "nearly 99 percent of them vanishing" is written as a modifier of the main sentence ("Five hundred million different species of living creatures have appeared on earth"). their vanishing describes their appearance? nope.

两个分句之间没有连接词，又不是主从句，run-on
