Perhaps cladistics is not cladistics any more.

Perhaps. Then again not having 'understood' might be leveled as what is
simply a different point of view.

Again, what is 'understood' is not necessarily absolute. Just look at
various algorithm crunchers criticize each other for not understanding
respective methods - despite all parties being active in the field. I was
once told that I could not criticize vicariance cladistics unless I could
do cladistic theory back to front (that ability being measured according to
the authority of said individual). Never mind that the individual did not
see the converse being necessary for panbiogeographic theory Naturally I
ignored that proposition.
>(That is why you will not find me arguing against panbiogeography.)
You will have noticed that several list members have commented and
sometimes debated panbiogeography without necessarily having a full
familiarity with either terminology or methodology. This has not prevented
me from attempting explanatory responses, and sometimes even from their
lack of familiarity with the subject they can still push me to the limits
of my own understanding for all that I might be more familiar with the subject.
