So, just voucher the specimens and let some other person have to
You apparently have me confused with someone else... not unexpected, since I
now see that the dysfuncional Microserf product I currently have to use did
not distinguish my comments from the original posting. To ensure that the
right people get blamed for the right things, I am editing the post below
with brackets around the parts that I wrote.
Thanks a bundle!

reminds me of Francis Fitzgerald's description of the American Command
in Vietnam, "..revolving on it's own axis with no exit into reality."]]

[[However premature and incomplete the resulting trees may be. An
interesting socio-political investigation would be how NSF went from =
forward-looking funder of biodiversity workshops in the early 1990=B4s
to the dogmatic pusher of "cladocule-isim" of the present day.]]

[[Well, you can also try talking to the thousands of scientists, citizen
activists and just plain interested folks all over the Third World who
are vitally interested in the biodiversity of their countries, and =
extremely curious to know what is living around them, what their names
are, and what their life histories are. And yes, their curiosity extends
to mites. I just came back from several days at a remote field station
in western Ecuador. I found an almost inexhaustable curiosity about the
local insects and invertebrates-including-mites from local farmers, their
children, conservation workers, and visiting agricultural scientists.
Oddly, nobody seemed particularly interested in what the insect=B4s
cladograms or gene sequences looked like.]]

[[In other words, "knowing more and more about less and less."]]

[[Thanks for bringing up the issue and framing it so well.
