The 94 Convoluta reason for utilizing the ribosomal partition alone was to Meara Nemertinoides make data more comparable with previously published 61 Nemertoderma metazoan phylogenies, which were mostly based on 57 Haplognathia ribosomal genes.

It is therefore the intention of this article to test morphological hypotheses for the position of Micro- gnathozoa among the protostome animals, using mole- cular evidence. Originally described as a new class of echinoderm NSRCand The strict consensus of both trees 60 Turbanella Urodasys Fig.
