[SC悬赏令] 一道OG16 verbal 题

Recently discovered fossil remains strongly suggest that theAustralian egg-laying mammals of today are a branch of the main stem ofmammalian evolution rather than developing independently from a commonancestor of mammals more than 220 million years ago.

                A.            rather than developing independentlyfrom

                B.            rather than a type that developedindependently from

                C.            rather than a type whose developmentwas independent of

                D.            instead of developing independentlyfrom

                E.            instead of a development that wasindependent of

我的问题是关于C 选项：它的问题是除了 whose development was independent of 没有developed independently from 简洁外，OG 解释中还提到 idiom 搭配中 independent of 和 independently from 的语义不同。

但找了很多词典和Manhattan 的idiom 章节都没有找到它们的区别。

求高手指点。

谢谢
