Eukaryotes Bacteria Arguments Convinced Biologists Structural Functional Differences

意群训练： Moreover ，arguments pointing out the extent of both structural and functional differences between eukaryotes and true bacteria convinced many biologists that the precursors of the eukaryotes must have diverged from the common ancestor before the bacteria arose .

标志：Moreover , arguments {pointing out the extent［of both structural and functional differences (between eukaryotes and true bacteria)］}convinced many biologists that the precursors (of the eukaryotes) must have diverged /from the common ancestor/ /before the bacteria arose/.

译文： 而且，一些个 {指出了［（eu和 真细菌之间 的）结构和 功能上的不同的］程度的}论据 使得 很多生物学家们 相信 ，（eu的）祖先们 一定是 /在细菌的出现之前/ /从其共同祖先那里/分化出来的 。

解释： 主句的主语arguments 在被层层修饰了之后变得极长，令读者看到convinced 的时候已经不知道它是谓语，也不知道主语在哪里了。convinced带着一对双宾语，第一个是many biologists ，第二个是that 引导的宾语从句。
