Recently discovered fossil remains strongly suggest that the Australian egg-lying 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)
(B)        rather than a type that developed in dependently from
(C)        rather than a type whose development was independent of
why the answer is B NOT C???

从句意上虽然看不出设么区别，但是从并列的角度来看

B a branch 和 a type 并列
C a branch , 但是后面的重心变成了development,

所以我觉得B 好

open to discussion

B和C 在并列上没区别。
关键是DEVELOP，能用动词时就不选用名词的。

C 罗嗦之至。

understand the sentence;
in b, ...a type... from...ancestor
in c, ....development... of ..ancestor

ＯＧ的英文解释有详细说明，Ｃ引起了歧义：
ｂ.rather than 后面指 Austrａliaｎ M 和 main stem M hv common ancestor.
C. rather than 后面指　Austalian M 和 common ancestroｒ 是兄弟，而不是父子关系。

ＥＴＳ一般不支持这种对original meaning 的改变。
