I disagree. The question, > Has science ever observed speciation via natural selection amongst a sexually reproducing cohort? posits a world where we can iteratively ask-and-answer questions if scientists are paying attention to speciation. The fossil record provides many many snapshots of different beings, from which we can infer speciation. By seeing the split _as it happens_, we can test hypotheses.

It seems to imply a dichotomy in value between seeing "as it happens" and the fossil record. Some of the most definitive proof of speciation is the actual fossil record, while simulations or purpose constructed experiments typically achieve the desired results of their authors.
