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
这个题选2是没错，但是我看og上的解释时候对3项有疑问
og上说的是3项改变的原来的意思，说3项的言外之意就是，除了有一种是development was independent of a common ancestor of mammals 还有一种是develop from a common ancestor of mammals 我怎么就看不出来这样的意思，能帮我说说么？

B. 从共同祖先那里独立发展的type
C. 它的发展过程与共同祖先不同。但也有可能还是从共同祖先那里独立发展的。
就与branch矛盾。
