Read's query is a very valid request for explanation. The insistence that
patterns of distributions of organisms can only be discussed within the
context of specific methodological principles of panbiogeography suggests
to me that panbiogeography is a trivial or meaningless method. I see the
instance cited below as an example of an hypothesis that has failed a test
and needs to be re-evaluated - not from the methodological side, but from
the data side. Better adherance to the scientific method is called for.
