Gastrotricha and the metazoan phylogeny
Original language description
The phylogenetic position of the Gastrotricha within Bilateria and relationships among gastrotrich subgroups are reanalysed using morphological, developmental, nonsequence molecular, and ecological characters, together with the conserved regions of small-subunit ribosomal RNA genes (SSU rDNA). The analysis shows that traditional 'Macrodasyida' is a paraphyletic stemline of Chaetonotida, with Dactylopodolida, Redudajys, and Turbanellida as the basalmost gastrotrich groups. The 'Cycloneuralia hypothesis',which assumes sister group relationships between Gastrotricha and Ecdysozoa is supported. The sensitivity analysis of die combined dataset yields the following scheme of relationships of the main bilaterian clades: (1) Acoelomorpha is a basalmost bilaterian clade; (2) both Deuterostomia and Protostomia (less Acoelomorpha) are monophyletic; (3) the phylogenetic position of Ectoprocta, Brachiopoda + Phoronida, and Cycloneuralia within Protostomia is unstable; (4) Trochozoa (incl.
