Dear Bob,
I think you might be confusing DNA barcoding with DNA taxonomy (or
perhaps you are equalling identification with taxonomy)? In any case, I
would like to point out that taxonomy is much, much more than
identifying species, and as a traditional taxonomist (who works with
species description, delimitation, identification, phylogeny,
classification, biogeography) I have discovered what a great tool DNA
barcoding is in my work on non-biting midges. In my opinion, DNA
barcoding will increase the need for taxonomists and not the opposite
since the DNA library on which DNA barcoding depends needs to be made
and maintained by taxonomic experts. - and as we know taxonomy is a very
dynamic science. As I see it, the possibility for automated species
identification will enable numerous large scale, multi taxon inventories
and biomonitoring. Something that we are quite unable to achieve with
our declining population of taxonomists today. And if DNA barcoding is
only able to identify the 90-95% most common species, that's just fine
with me: we can concentrate our efforts on the much more scientifically
interesting 5-10%. Wouldn't that be nice?
