ask og 143 again

143. Recently discovered fossil remains strongly suggest that the Australian egg-laying mammals of today are a branch of the main stem of mammalian evolution rather than developing independently from a common ancestor of mammals more than 220 million years ago.
(A) rather than developing independently from
(B) rather than a type that developed independently from
(C) rather than a type whose development was independent of
(D) instead of developing independently from
(E) instead of a development that was independent of

In C, the expression a type whose development was independent of a common ancestor states the opposite of the original point_that the type of mammal mentioned was thought to have developed independently of the main stem of mammalian evolution, but still to have descended from a common ancestor.

here i still do not understand this sentense,who can translate the whole sentense and the explaination of the og?

我的理解就是

rather than 前面是说  现今在澳大利亚发现的生蛋的哺乳动物是mammalian  evolution主系中的一个分支,也就是说和共同的祖先有关系

rather than 后面是令一种说法:这种哺乳动物不依赖哺乳动物共同的祖先而是独立进化来的

文章支持前一个观点

不知道这样理解对不对

so how to understand :"rather than a type whose development was independent of",sorry to ask such silly question,i find my head stuffed.

最近发现的化石表明：现在生存在澳洲的蛋生哺乳类动物是从主流的哺乳动物进化过程中进化过来的，而不是从另一个独立的分支进化而来，而这一个独立的分支在220万年前和哺乳类动物是同一个祖先(也即220万年前，这个独立分支和哺乳类动物之间发生进化分叉)。
stoneren注：1－蛋生哺乳类动物－即生蛋的那种哺乳类动物－好像是鸭嘴兽；2－a branch of the maim stem ofmammalian evolution主流哺乳类进化过程中的一个分支(即从主流的哺乳动物进化过程中进化过来的)；3－进化分叉的举例说明：N年前，人和猴子共享一个祖先A，突然有一天有一个东东走到地上去了，于是乎，从这天开始人和猴子发生了进化分叉，N年后，一部分当年的A进化成现在的人，另一部分A进化成现代的猴子。
希望解释清楚了，其实翻译不是琢字翻译的，意思应该差不多，如果不清楚就再跟贴问吧。

thanks,stoneren,i got it

C的错误在于whose的指代对象是type，也即type's development，这个搭配在逻辑上不很严密；而且independent of和independently from是两个完全不同的意思。

可不可以这样理解

a branch of the main stem of mammalian evolution（ rather than a type that developed independently ）from a common ancestor of mammals

而independent of就不能这样断，也就不是original point了

(B) rather than a type that developed independently from a common ancestor of mammals more than 220 million years ago.______即可理解为:" egg-laying mammals 从同一个祖先,独立地进化发展而来...."

(C) rather than a type whose development was independent of a common ancestor of mammals more than 220 million years ago._______理解为:" egg-laying mammals 的进化发展是独立于同一个祖先(暗示不是由同一祖先进化而来)"

所以解释说B,C两者表达意思相反.不知对不对,接受批判.

以下是引用DARRENMA在2005-6-24 17:43:00的发言：

(B) rather than a type that developed independently from a common ancestor of mammals more than 220 million years ago.______即可理解为:" egg-laying mammals 从同一个祖先,独立地进化发展而来...."

(C) rather than a type whose development was independent of a common ancestor of mammals more than 220 million years ago._______理解为:" egg-laying mammals 的进化发展是独立于同一个祖先(暗示不是由同一祖先进化而来)"

问题3种这个解释的更清楚一点，我觉得

OG说E   While a development may appear to parallel a branch,the logic of the sentence is contradicted by the meaning of this usage,

是什么意思啊,这种用法造成的矛盾之处在哪里呀???

谢谢指教
