E)clarified........reassess is the answer, IMO.

The clue here is ' for the first time'- meaning that the fossil or its study had not been utilised before in studying the evolution.Hence, reassess fits in better than ensure.

I think an even bigger clue is the distinction between ensure/reassess. No one can ensure evolution takes place(it is a natural phenomenon) but one can surely assess it (or measure it).
