Taxacom: degenerating research programs

[John Grehan]

Just a note for those interested in reference to that paper I asked about.
It was interesting to see this center of origin-chance dispersal paper
acknowledge "The relative importance of vicariance versus dispersal in
shaping biodiversity
distribution patterns remains contentious (Heads et al. 2023; Zink et al.
2000),"  Then they go on to ignore the fault lines of their methodology
outlined by Heads et al 2023 and proceed with the same worn out techniques
that have no empirical reality (mis representing clade ages as actual or
maximal, analysing the relationships of areas that don't exist (and as
usual, no direct information on the exact geographic ranges of the taxa],
and using center of origin methods that are incompetent to
empirically chose between vicariance or chande dispersal). I guess its a
step forward in openly recognizing that their are other perspectives, but
of course a long way to go to actually address the problems raised about
their method. Easier and obviously state of the art science to just ignore
that. Chaos reigns.

Cheers, John Grehan
