Annelida, the ringed worms, is a highly diverse animal phylum that includes more than 15,000 described species and constitutes the dominant benthic macrofauna from the intertidal zone down to the deep sea. A robust annelid phylogeny would shape our understanding of animal body-plan evolution and shed light on the bilaterian ground pattern. Traditionally, Annelida has been split into two major groups: Clitellata (earthworms and leeches) and polychaetes (bristle worms), but recent evidence… Expand
Illuminating the base of the annelid tree using transcriptomics.
TLDR
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. Expand
Phylogeny of Annelida
TLDR
The phylogeny of Annelida was split into two major clades, one clade adapted to an errant mobile life and the other which includes earthworms and leeches, to a more sessile, sedentary one. Expand
Articulating "Archiannelids": Phylogenomics and Annelid Relationships, with Emphasis on Meiofaunal Taxa.
TLDR
A new Illumina-based data set is generated to address annelid relationships from a fresh perspective, independent from previously generated data and with nearly fully occupied matrices, and largely corroborate the phylogenomic results of Weigert et al. (2014). Expand
Current status of annelid phylogeny
TLDR
The new annelids phylogeny highlights the variability and lability of annelid body plans, and many instances of simplifications of body plan as adaptations to new life styles can be found. Expand
The origin of annelids
TLDR
A novel clade of machaeridians, the Cuniculepadida, is identified, which exhibit a series of adaptations for burrowing, and is identified as a convincing body of molecular evidence that polychaetes form a paraphyletic grade and that clitellates are derived polychaETes. Expand
Recent progress in reconstructing lophotrochozoan (spiralian) phylogeny
TLDR
New evidence supporting the inclusion of chaetognaths within gnathiferans, the phylogenetic position of Orthonectida and Dicyemida, as well as the general phylogeny of lophotrochozoans is reviewed. Expand
FRONTIERS IN PALAEONTOLOGY THE ORIGIN OF ANNELIDS
TLDR
A novel clade of machaeridians is identified, the Cuniculepadida, which exhibit a series of adaptations for burrowing, which is a convincing body of molecular evidence that polychaetes form a paraphyletic grade and that clitellates are derived polychae- tes. Expand
The impact of fossil data on annelid phylogeny inferred from discrete morphological characters
TLDR
A reinvestigation of the morphology of key fossil taxa is presented and analyses using probabilistic methods and both equal- and implied-weights parsimony recover paraphyletic polychaetes and support the conclusion that echiurans and clitellates are derived polychaETes. Expand
Evolution of mitochondrial gene order in Annelida.
TLDR
It is demonstrated that the supposedly highly conserved mitochondrial gene order suggested for Annelida is restricted to Pleistoannelida, representing the ground pattern of this group and the first mitochondrial genomes in AnnelIDA that encode genes on both strands are reported. Expand
Phylogenomics of tubeworms (Siboglinidae, Annelida) and comparative performance of different reconstruction methods
TLDR
Every analysis conducted herein strongly supported Osedax being most closely related to the Vestimentifera and Sclerolinum clade, rather than Frenulata, as previously reported, and the alternative hypothesis that frenulates andOsedax are sister groups to one another was explicitly rejected by an approximately unbiased (AU) test.

Annelid phylogeny and the status of Sipuncula and Echiura
TLDR
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. Expand
Phylogeny of Annelida (Lophotrochozoa): total-evidence analysis of morphology and six genes
TLDR
The combined ("total-evidence") phylogenetic analysis provides a modified view of annelid evolution, with several higher-level taxa, i.e. the monophyly of the Aciculata, sister-group relationships between the Eunicida and OPC, between the Cirratuliformia and SSC, and possibly also between the "Clitellatomorpha" and Oweniidae-Pogonophora clades.

TLDR
This result, indicating the derived loss of segmentation in echiurans, has profound implications for the understanding of the evolution of metazoan body plans and challenges the traditional view of the phylum-level diversity and evolutionary relationships of protostome worms. Expand
Phylogenetic position of Sipuncula derived from multi‐gene and phylogenomic data and its implication for the evolution of segmentation
TLDR
It is revealed that Sipuncula had secondarily lost segmentation, which does not support the hypothesis that the last common ancestor of Annelida, Arthropoda and Chordata was segmented, assuming several losses along the branches leading to them. Expand
On the phylogenetic position of Myzostomida: can 77 genes get it wrong?
TLDR
It is concluded that reliance of a set of markers belonging to a single class of macromolecular complexes might bias the analysis, and that concatenation of all available data might introduce conflicting signal into phylogenetic analyses. Expand
Mitochondrial genome and nuclear sequence data support myzostomida as part of the annelid radiation.
TLDR
The molecular data are in agreement with the morphological evidence that myzostomids are part of the annelid radiation and probably evolved from a segmented ancestor and gained a derived anatomy during their long evolutionary history as echinoderm symbionts. Expand

AbstractClitellata, with more than one third of all annelid species described, is briefly introduced, and an overview of the hypotheses of phylogenetic relationships among the groups traditionallyExpand
Phylogenetic position of Nemertea derived from phylogenomic data.
TLDR
Nemertea and Platyhelminthes have traditionally been grouped together because they possess a so-called acoelomate organization, but lateral vessels and rhynchocoel of nemerteans have been regarded as coelomic cavities, where Nemertea is most likely due to a secondary reduction of the coelom as it is found in certain species of Mollusca and Annelida. Expand
Phylogenomic analyses of lophophorates (brachiopods, phoronids and bryozoans) confirm the Lophotrochozoa concept
TLDR
These analyses show that the three lophophorate lineages are affiliated with trochozoan rather than deuterostome phyla, and all hypotheses claiming that they are more closely related to Deuterstomia than to Protostomia can be rejected by topology testing. Expand
