[Taxacom] Molecules vs Morphology‏

[Richard Zander]

It's a Historical Narrative Explanation of a one-time event, not a Nomological Deductive Explanation. See
Bock, W. J. 2004. Explanations in systematics. In: D. M. Williams DM & P. L. Forey  (eds.). Milestones in Systematics. Systematics Association Special Volume 67: 49–56.

Apparently there is a confusion between figuring out universals, using physics' "least action" versus figuring out historical events, using phylogenetics similar but different "parsimony." Bock admits his fault but has the grace to explain a better way.

Snip:
"That is the hypothetico-deductive model which I have to insist asking again, are you using it or do you use a different one?"
