[Taxacom] Reproducibility of phylogenetic analysis

Interesting exchange here. It reflects the difficulty of checking
results in systematics. If we could test a process against examples of
the process, bob's your uncle. But only part of systematics is process
(evolution) the rest consists of a series of one-time historical events
(speciation events and the like). Evolution we can test, with
difficulty, as a process, but cladograms and phenograms are usually
treated as things in themselves, the ends of analysis.

Gosh, Stephen,that sounds amazingly like the criticisms of phenetics
that lead (in part) to the cladistic revolution - too many ways to
determine similarity and find clusters.

The more things change, the more they stay the same!
