语法：状语比较的省略问题

杨梅希果

Digging in sediments in northern China, evidence has been gathered by scientists suggesting that complex life-forms emerged much earlier than they had previously thought.
A.evidence has been gathered by scientists suggesting that complex life-forms emerged much earlier than they had
B.evidence gathered by scientists suggests a much earlier emergence of complex life-forms than had been
C.scientists have gathered evidence suggesting that complex life-forms emerged much earlier than
D.scientists have gathered evidence that suggests a much earlier emergence of complex life-forms than that which was
E.scientists have gathered evidence which suggests a much earlier emergence of complex life-forms than that

这道题第一次做错了，第二次凭着感觉做对了，再次分析的时候发现自己第一次分析的有些问题。
我知道这道题考的是状语比较的省略，但省略的是哪部分内容，即thought修饰的是哪部分内容呢？
我之前分析的是（scientists）previously though （that complex life-forms emerged），因为前面有个suggesting，这次分析看了很多大神的回答，感觉这个分析的有些问题，麻烦各位友友解答一下，谢谢大家！！

各位大神在吗，也可以帮忙分析一下选项吗，谢谢大家！

GmatLa的大神是这样解答的：

题目分析：
题目的开头是一个现在分词短语（Digging in sediments in northern China），句首出现的现在分词短语肯定是伴随状语。  

选项分析：

A选项：伴随状语中的现在分词的主语在语法上和其修饰的句子的主语相同，在本选项中，其主语为evidence。但是，在逻辑上，能挖出沉淀物的只能是“人”，而不能是“证据”。比较对象不对等。本选项than后面用了过去完成时，而过去完成时表达的是在某个过去时的过去，即，emerged的过去。但显然地，“科学家认为”这个事件不可能发生在emerge这个动作之前。

B选项：Digging的主语错误同(A)；本选项中suggest的宾语是一个名词短语（a much earlier emergence of complex life-forms），这是不正确的，suggest（表明）身后通常只能跟宾语从句。这点考查了“名词和从句的区别”。用之于本题，即：
evidence gathered by scientists suggests a much earlier emergence of complex life-forms
是不正确的。这是因为，证据表明的事情，通常是一个事实，而虽然“出现（emerge）”这个动作有终点，但是这个事实是一直存在的，即，事实不具有时间的概念，自然没有时间终止点。只能用宾语从句。
另外，比较对象错误同(A)。

C选项：Correct. 本选项在逻辑和语法上均是正确的。

D选项：suggest的宾语是一个名词短语（a much earlier emergence of complex life-forms）错误同(B)；比较对象不对等。that是代词，指代对象仅能是一个名词，而本题真正对比的应该是两种情况（真实情况vs科学家以前认为的情况）。

E选项：本选项错误同(D)。

感谢！我还想问下，C答案than后面省略的部分是什么呢？

刚做另一题有些灵感，或许省略的是：than (they were) previously thought
