This one's tricky but here's my breakdown and conclusion for choice A:

Birds' feathers appear to have evolved from dinosaur scales well over 100 million years ago, Chinese scientists have shown, based on a fossil bird found in the Yixian mountains of northern China.

A. Chinese scientists have shown, based on a fossil bird found in the Yixian mountains of northern China. The pair of commas around ",Chinese scientists have shown," seems to be read as a misplaced clause or at least one without a connecting word. In actuality, it indicates that it's not really essential but could be moved around (ie. beginning of the sentence) without distorting the overall meaning.
B. Chinese scientists have shown a fossil bird found in the Yixian mountains of northern China.
Changes the meaning of the sentence.

C. Chinese scientists showed, based on a fossil bird found in the Yixian mountains of northern China. "have shown" indicates change over time and is parallel to "have evolved". "showed" is not parallel and changes meaning

D. when the Chinese scientists found a fossil bird in the Yixian mountains of northern China.
I don't think this one really changes the meaning per se, but the comma shouldn't be there before this dependent clause.

E. which the Chinese scientists say can be proven from a fossil bird which they found in the Yixian mountains of northern China.
too wordy and use of 'which' is inappropriate since it's essential to the sentence (ie. reason for why bird feather's have evolved from dinosaur scales)
