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

1. complex life-forms emergedthan previously thought 这里省略了一些话吧？是什么呢？是that that(the time when complex flie-forms emerge) they(scientist) previously thought
可以这样理解吗？
有些说法说这是一种固定搭配，但私以为不太像
2.which用错了吗，是否必须用that？

求教ＮＮ

than usual/ ever before/ previously expected/previously estimated/ anticipated…等,这些词都不表示具体的时间，并不要求比较对象前后的平行，并不需要第一个比较对象出现状语。

状语比较： A do sth than usual/everbefore/people expected(直接加状语）

那么是不是now, last year就算具体时间,如果想要在比较句型中省略，就需要给第一个比较对象补足时间状语呢？
