I just want to clarify that the above quote is prior to Willi Henning's
Grundzuge einer theorie der phylogenetischen systematik of 1950.
Phylogenetic Systematics only came out in 1966. Therefore I am assuming that
the term "phylogenetic concept" used above in the quote is not homologous to
the one used by Henning. The words might be the same, however the idea are
quite different. I don't want to stir up this pot more than it already is,
but we should keep the concepts with precision. This might help to keep
us in the right track, if such concept applies.
