OG12第128题---suggest用法

susielei

看了很多帖子，都说suggest有如下三种用法：
1、suggest doing sth
2、suggest sth
3、suggest that+动词原形---表示虚拟语气。
可是OG12上的第128题，如下：
Australian embryologists have found evidence （that suggests that the elephant is descended from an
aquatic animal, and its trunk originally evolving ）as a kind of snorkel. ----划线部分用括号表示
(A) that suggests that the elephant is descended from an aquatic animal, and its trunk originally evolving
(B) that has suggested the elephant descended from an aquatic animal, its trunk originally evolving
(C) suggesting that the elephant had descended from an aquatic animal with its trunk originally evolved
(D) to suggest that the elephant had descended from an aquatic animal and its trunk originally evolved
(E) to suggest that the elephant is descended from an aquatic animal and that its trunk originally evolved  
此题选E，suggest that后面貌似没有用动词原形啊，望NN指点~~~~

如果是表明的意思的话，suggest that就不需要有动词原形的限制吗？看了一些总结，都只有提到之前说的三种用法。
