In a fine obituary for Douglas Rossman (1936-2015), Larry David Wilson and Jeff Boundy, both former graduate students of his, noted in passing that Rossman remained skeptical of molecular systematics:
"As the techniques for DNA extraction and sequencing advanced, and new phylogenies were constructed that were solely based on sequences, Doug became increasingly discouraged by the results. A typical complaint from 2011 reads 'As I have said before, the molecular folks are self-admittedly trying to base their phylograms on "selectively neutral mutations" and, in so doing, are deliberately assessing the effects of [genetic] drift and ignoring selection, which I would contend is the chief driving force of evolution since it is where the "survival rubber hits the road" for individual species.'
It is somehow satisfying to know that one of the greats had shared my own skepticism of current molecular techniques and the conclusions drawn from them.
