Brachiopod molecular phylogeny advances

Phoronis vancouverensis sequence was determined de novo and found to be erroneous its correction resulted in improved support for phoronid monophyly and the phoronid-H inarticulate brachiopod clade, but the possible relationship with craniids remained weak (Cohen, 2000). That brachiopods and phoronids appear mono-phyletic was also supported by a combined molecular and morphological study (Zrzavy et al., 1998) and reclassification of Phoronida as a sub-phylum Phoronifor-mea within the Brachiopoda was therefore proposed (Cohen, 2000). Zrzavy et al. (1998) alternatively suggested that the entire clade should be designated as phylum Phoronozoa. 

This paper reports 18S rDNA sequence results from some new taxa, describes some important corrections to the 18S tree, and outlines new results from the analysis of mitochondrial DNA sequence divergence in Terebratulina spp. and other cancellothyridids (Liiter and Cohen, submitted).
