Question
According to the NOVA documentary on evolution that we watched in class, Dr Neil Shubin and his collaborators predicted, based on modern Darwinian theory and other scientific considerations, that they would find the fossilized remains of a transitional species that linked lobe-finned fish with the earliest known tetrapods at a specific geographical and stratiographic location. The documentary further relays that Dr. Shubin and his collaborators did indeed identify the "missing link" in the form of the fossilized remains of tiktaalik. The prediction and discovery of tiktaalik are said to provide powerful confirmation of Darwinain theory, especially as it pertains to the macroevolution of lobe-finned fish into tetrapods. The fascinating story of the prediction and discovery of tiktaalik is told at the following website,

Science, however, is a moving and tentative enterprise, as new facts and interpretations can overturn seemingly settled hypotheses and theories. With that in mind, Biochemist Dr. Fazale Rana has provided critical commentary of the tiktaalik story in the form of an article and podcast:

After reading Dr. Rana's article and listening to the podcast, select the answer that best summarizes Dr. Rana's position on tiktaalik.
A. The fish-to-tetrapod evolutionary story was always solid, and the recent discovery of 397 million year old tetrapod tracks only serves to further confirm it.
B. The fish-to-tetrapod evolutionary story was always problematic, but the recent discovery of 397 million year old tetrapod tracks serves to confirm it.
C. The fish-to-tetrapod evolutionary story was always problematic, but the recent discovery of 397 million year old tetrapod tracks serves to weakly disconfirm it.
D. The fish-to-tetrapod evolutionary story was always problematic, but the recent discovery of 397 million year old tetrapod tracks serves to "blow it out of the water" and totally falsify it.

Explanation / Answer
Answer:
Option D
The fish-to-tetrapod evolutionary story was always problematic, but the recent discovery of 397 million year old tetrapod tracks serves to "blow it out of the water" and totally falsify it.
