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
Choice B, the best answer, correctly uses the construction mammals ... are a branch... rather than a type, in which the terms compared by rather than are grammatically parallel nouns. Choices A and D fail to parallel branch with another noun, instead following rather than or instead of with the verb phrase developing independently from.... 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. Choice E repeats the error of C, further straying from the intended meaning by referring to the type as a development.

我想问的是C的解释是什么意思啊？？？

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.

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.
意思是说，原文表达的是这个东西虽然不是哺乳动物进化的主线，但还是从一个共同祖先进化过来的，而be independent of 的表达是两者全不相干.
