[Taxacom] more science nonsense

Stephen - the point I was making is that evidence is contingent, not self
evident. Thus, fingerprints on a murder weapon is indeed evidence of
something - it could be true or false as evidence (and it is not even
necessarily evidence that one touched the weapon). The meaning of evidence
depends on context. As evidence, it is not self evident as to what that
evidence means. Same goes for the existence of a fossil and taxon at a
particular time and place. It is not self evident that the oldest fossil
represents the earliest origin (which is what molecular systematists
continue to claim) or that it represents anything to do with an imagined
center of origin even if the fossil is the oldest and most basal group.
Such inferences are imposed upon the information according to previously
ascribed viewpoints. Those viewpoints are open to challenge. It is my
contention that it is nonsense to suggest the representation of the
earliest fossil of a basal lineage as having something to do with an
imagined center of origin. And so far the only responses in defense of
making that connection have failed to demonstrate that there is any such
connection - which does not surprise me as Darwin's center of origin to
explain the origin of allopatry was a purely theoretical notion that
'captivates the mind'.
