The primary output from phylogenetics programs is tree diagrams depicting the relationships among organisms. Very clean, very crisp, very precise diagrams. Precision isn’t in itself a problem, but for the human foible of mistaking precision for accuracy.
I’m not interested in a precise estimate of evolutionary history so much as a correct one. I’m reminded as much when I see my estimates change from one precise conclusion to another as I add more data from more species. The razor-sharp output from the algorithms is seductive.
