[Taxacom] OMG! DNA only descriptions (with one habitus photo)!

 One of my main worries with this approach is that it seems pretty obvious that they are basing their judgements of species distinctions on a cursory and superficial morphological examination and then assuming that the associated DNA profiles define species! Obviously, however, every individual organism has a different DNA profile, and I doubt that any categorical genetic genetic distance between speciesĀ applies across the board, so, when all said and done, all we have here is one photo of possibly limited diagnostic value and a DNA sequence for that same individual! This is not taxonomy as we know it! They should have known that DNA really stands for Do Not Attempt!

 Revolutionary? Not at all. Especially given the largely toothless opinions
regarding species and taxa overall that permeate biology. This is just
another instance of technology driving science at the expense of the
established principles upon which science is supposed to be based.
