Journal ArticleDOI
The unholy trinity: taxonomy, species delimitation and DNA barcoding
TL;DR: A phylogenetic systematic framework for an improved barcoder as well as a taxonomic framework for interweaving classical taxonomy with the goals of ‘DNA barcoding’ are presented.
Journal ArticleDOI

TL;DR: It is indicated that the Myxozoa are closely related to Cnidaria, and marine taxa at the genus level branch separately from genera that usually infect freshwater fishes; taxa cluster more by development and tissue location than by spore morphology.
Journal ArticleDOI
Higher level relationships of leeches (Annelida: Clitellata: Euhirudinea) based on morphology and gene sequences.
TL;DR: Results suggest that the nuclear 18S rDNA gene yields a meaningful historical signal for determining higher level relationships, andBiogeographic patterns supported a New World origin for Arhynchobdellida, and analyses combining all data from the three character sets yielded one most-parsimonious tree.
Journal ArticleDOI
The demise of a phylum of protists: phylogeny of myxozoa and other parasitic cnidaria
TL;DR: Reassessment of myxozoans as metazoans reveals terminal differentiation, typical metazoan cellular junctions, and collagen production, and it is recommended that the group as a whole be removed from all protistan classifications and placed in a more comprehensive cnidarian system.
Journal ArticleDOI
A molecular phylogeny of annelids
TL;DR: Parsimony analyses of annelids based on the largest taxon sample and most extensive molecular data set yet assembled suggest that the poor resolution in the basal parts of the trees presented here may be due to lack of signal connected to incomplete data sets, rapid radiation events and/or uneven evolutionary rates and long‐branch attraction.
