Taxonomic Ideas

Lenore and Students,
I am not currently working in the field of taxonomy but the most
interesting questions to me are 1) How will evidence from DNA change our
concepts, i.e., the boundaries of taxa? and 2) Will knowledge gained from
DNA change our definition of what is a species? a genus?  a family?  etc.
[I've been around plant biology since the mid 1950's and have seen how new
kinds of evidence (chemical taxonomy, palynology, anatomy, and now
molecular genetics) have changed not only concepts but methodology and the
training of taxonomists.]

Not so much an "idea" of taxonomy but a concern is whether we can learn
about yet undiscovered taxa before they are destroyed through habitat
destruction.  Are we training taxonomists today who are well prepared for
field work or are we putting too much emphasis on molecular studies that
might rarely take one out of the lab?  Who will slog through the rain
forest in search of the new species?  Of course, much of this hinges on a
more basic question:  How will taxonomic studies (and the training of
taxonomists) be funded if the support of government is withdrawn or
severely diminished?

I doubt that this will stimulate much discussion in your class but I didn't
want your students to think that none of us pay any attention to student
questions!  By the way, it's wise to put something in the "subject" line
because this establishes a "thread" that will generate an ongoing dialogue.
