Bryozoan phylogeny

Staff at the Natural History Museum are investigating the molecular phylogeny of bryozoans using DNA sequences from:

  • 2 nuclear ribosomal genes: 18S and 28S rDNA
  • 5 mitochondrial genes: 16S and 12S rDNA, cytochrome b, and cytochrome oxidase subunits 1 and 3

This research is supported by a grant from the Natural Environment Research Council.

Our preliminary results:

  • support the monophyly of the Bryozoa
  • place the freshwater phylactolaemates as the primitive sister-group of marine bryozoans
  • show that for one order, Cyclostomata, there is marked incongruence between molecules and morphology
