Annelid phylogeny and the status of Sipuncula and Echiura
Using multiple genes and explicit hypothesis testing, it is shown that Echiura, Siboglinidae, and Clitellata are derived annelid with polychaete sister taxa, and that Sipuncula should be included within annelids.
Platyzoan paraphyly based on phylogenomic data supports a noncoelomate ancestry of spiralia.
Platyzoan paraphyly suggests that the last common ancestor of Spiralia was a simple-bodied organism lacking coelomic cavities, segmentation, and complex brain structures, and that more complex animals such as annelids evolved from such a simply organized ancestor.
Phylogenomic analyses unravel annelid evolution
It is shown that phylogenomic analyses of 34 annelid taxa, using 47,953 amino acid positions, recovered a well-supported phylogeny with strong support for major splits and Ancestral character trait reconstructions indicate that these clades show adaptation to either an errant or a sedentary lifestyle.
Illuminating the base of the annelid tree using transcriptomics.
This study based on transcriptomic data comprising 68,750-170,497 amino acid sites from 305 to 622 proteins resolves annelid relationships, including Chaetopteridae, Amphinomidae, Sipuncula, Oweniidae, and Magelonidae in the basal part of the tree.

TreSpEx (Tree Space Explorer) now combines different approaches (including statistical tests), which utilize tree-based information like nodal support or patristic distances (PDs) to identify misleading signals.
Phylogeny of Eunicida (Annelida) and exploring data congruence using a partition addition bootstrap alteration (PABA) approach.
The definition of both the labidognath and ctenognath jaw type does not address adequately the variation within Eunicida and thus misleads current evolutionary understanding, and a symmetric maxillary apparatus with a carrier and four to six maxillae is most likely the plesiomorphic condition for EunicIDA.
Finding Evolutionary Processes Hidden in Cryptic Species.
New phylogenomic data support the monophyly of Lophophorata and an Ectoproct-Phoronid clade and indicate that Polyzoa and Kryptrochozoa are caused by systematic bias
The phylogenetic analyses strongly support the monophyly of Lophophorata and a sister-group relationship between Ectoprocta and Phoronida, indicating that the support for Polyzoa, Brachiozoa and Kryptrochozoa gathered so far is likely an artifact caused by compositional bias.
