Figure 7 in Ultrastructure of the pseudocnidae of the palaeonemerteans Cephalothrix cf. rufifrons and Carinomella lactea and an assessment of their phylogenetic utility
Figure 7. Molecular phylogenies of nemerteans. (A) Phylogeny inferred from 18S rDNA sequences. (B) Phylogeny inferred from a simultaneous analysis of partial 28S rRNA, H3, 16S rRNA and COI gene sequences. Phylogeny ''A'' implies that pseudocnidae were present in the common ancestor of nemerteans and subsequently lost in two lineages Phylogeny ''B'' implies independent evolution of pseudocnidae. Open boxes represent character losses and solid boxes represent character acquisitions.
