- This is strikingly illustrated if we just consider character choice in two subsequent publications by the same research group, for example, for placing the ‘acoelomate’ worms, Platyhelminthes, Nemertea, and Gnathostomulida.
- This structure was first described by Rieger and Tyler in the jaws of Gnathostomulida and Rotifers.
- Two others are probably too specialized and may turn out to be protostomes (and ecdysozoans in particular): the Chaetognatha and Gnathostomulida.
- Also unresolved are the phylogenetic positions of Cycloneuralia, Chaetognatha, Gnathostomulida, Cycliophora, and Micrognathozoa.
