Abstract
Cladistic analyses will be inaccurate if based on inaccurate data. Most blastozoan taxa were defined before cladistics was proposed. Redescription of precladistic taxa should be a priority. Cladistics recognizes similarities between taxa, not differences. Differences always exist, so the two approaches are asymmetrical. Any suggested similarity or homology needs testing, including output of computer-based analyses. New interpretations of plate homology between glyptocystitoid and hemicosmitoid rhombiferans had already rendered input data obsolete before the pan-dichoporite paper was published. Universal Elemental Homology (UEH) is not a scientific hypothesis. It makes no testable predictions; no system of naming plates can.
期刊介绍:
Acta Palaeontologica Polonica is an international quarterly journal publishing papers of general interest from all areas of paleontology. Since its founding by Roman Kozłowski in 1956, various currents of modern paleontology have been represented in the contents of the journal, especially those rooted in biologically oriented paleontology, an area he helped establish.
In-depth studies of all kinds of fossils, of the mode of life of ancient organisms and structure of their skeletons are welcome, as those offering stratigraphically ordered evidence of evolution. Work on vertebrates and applications of fossil evidence to developmental studies, both ontogeny and astogeny of clonal organisms, have a long tradition in our journal. Evolution of the biosphere and its ecosystems, as inferred from geochemical evidence, has also been the focus of studies published in the journal.
