Taxacom: Science fraud - Nature

[John Grehan]

Fred - You hit the nail on the head I think: " real problems in framing an
historical narrative about evolutionary divergence with both the ad hoc
invocation
of long distance dispersal and ad hoc association of divergences with
a geological narrative." Agree fully. That is where panbigoegraphy steps
outside the 'ad hoc' by providing tectonic (not historical narrative)
correlation. No matter what one believes about the history of a tectonic
structure, no scientist (that I know of) denies the existence of these
structures (spreading ridges, transform faults, rift zones etc). Spatial
correlation provides an empirical spatial relationship that demands
explanation one way or the other. Dispersalists simply chose to ignore it
(usually be incorrectly asserting that younger molecular ages
falsify earlier origins).

"The claim is that when there are two competing classes of hypotheses like
this, it's fraudulent to publish an account which doesn't take both kinds
of explanations into consideration." That's right. In just about any other
field such consideration would be seen to be essential for the credibility
of the science. Not in disperslist molecular (CODA) biogeography
apparently. Sppression and censorship is held up to be a virtue - at least
openly by Jonathan Waters et al. and an acceptable viewpoint by publishers
such as Systematic Biology.

Cheers, John
