Well, let's see, stating that my comments are mere "empty name calling" for
starters.... My name calling is never empty. And I am proud to consider
myself a radical revolutionary in the field of phylogenetics, along with my
predecessors -- Darwin and Wallace and deQueirez and Gauthier. In his day,
most wanted Darwin to walk the plank because of his pioneering ideas that
went against all creationist traditions. Lesson #1 from the history of
biology: We all should be thankful that Darwin's revolutionary views won out
(in all parts of the world except Kansas...).

History is important - in pointing the way to the future. There is a problem
when science and scientists cling to the past and past ideas simply because
they have been around for a long time. I am not advocating an overthrough of
all biological ideas pre-1990, but when we know a system is flawed why do we
continue to use it? We no longer teach that human sperm contain a minute
human fetus. This idea is much simpler to comprehend than meiosis, diploid,
haploid, fertilization, etc. But it is wrong, so we teach the more
difficult, but correct version of how babies form. Biology is not always
simple or easy to understand. Lesson #2 from the history of biology: When
our system is wrong, we ought to admit it, fix it, and move on.

Linnaeus was a creationist and he designed his taxonomy to reflect how he
interpretted God's creation of organismal groups (i.e., his view of how
organisms arose on earth), so my use of "creationist-based views" should not
startle you. In many cases the characters he chose happened to reflect the
evolutionary history of the group (number of stamen in many cases). However,
he erred in the selection of other characters (number of carpels). Linnaeus'
classification did reflect his personal observations, wrong though they be.
His classification was changed because someone realized that his
observations were skewed (i.e., did not adequately reflect natural lineages
based on the observation of additional or alternative characters).
The reason the old system has weathered is because in some cases, biologists
did not realize that their character choice or interpretation did not
reflect evolutionary history. "Revolutionary" techniques such as DNA
sequencing allow us to ignore plasticity which often is inherent in
morphological characters, and misinterpretation of such plastic characters.
Now we deal with the genotype, which should reflect the evolutionary history
of the taxon, while allowing us to be unbiased in our interpretation. If the
point of classification is to reflect natural groups (=phylogeny), and DNA
sequencing allows us to determine phylogeny in an unbiased fashion, then
classification is going to have to change to reflect the phylogeny.
Lesson #3 from the history of biology: Sometimes new IS better.

How unfortunate that some people cannot see future endeavors because of an
adherence to 'historical facts'.

Until you also perceive the problem then any solution I were to provide
would only cause apoplexy on your end. And more email on my end than I could
