英语语法问题（sat）
the evolution of the platypus,originally called the watermole,is still a mystery to the biologist.
originally called the watermole为什么一定修饰 Platypus,sat不是有考前原则吗?为什么不是修饰evolution.如果是定语从句先行词应该不能省略的?
那为什么 把originally called the watermole提前就不对了 这是sat的sentence improving 我只说了两个选项！

不知道谁告诉你靠前原则的,因为SAT的OG上面一直都是强调就近原则的（这也是为什么非限定性定语从句从来不考）.在这里originally called watermole是插入语作定语,不是从句.如果把它提前,那么就变成了“插入语在句首修饰主语”的情况,而这样修饰对象就变成了evolution.
有时候应该了解一下句子的意思.watermole这种东西一看不是个常见词,你就应该想到这是一种水里的东西,最起码和进化没关系,应该猜一猜.加油吧

You need to understand the meaning of the sentence - could you possibly call evolution the watermole? So the middle part could only stand for platypus.

originally called the watermole不是定语从句，而是定语。
从结构上讲，这个定语可以修饰evolution, 也可以修饰platypus, 但从意思上讲，它只能修饰platypus,因为，evolution 就是evolution，它不可能有另外一种叫法，而platypus 从前的名字不是platpus,而是watermole.
