Almost a decade ago, a new phylogeny of bilaterian animals was inferred from small-subunit ribosomal RNA (rRNA) that claimed the monophyly of two major groups of protostome animals: Ecdysozoa (e.g., arthropods, nematodes, onychophorans, and tardigrades) and Lophotrochozoa (e.g., annelids, molluscs, platyhelminths, brachiopods, and rotifers). However, it received little additional support. In fact, several multigene analyses strongly argued against this new phylogeny. These latter studies were…

Deep Genomic-Scale Analyses of the Metazoa Reject Coelomata: Evidence from Single- and Multigene Families Analyzed Under a Supertree and Supermatrix Paradigm

It is shown that optimal outgroup selection is key in avoiding LBA and the use of inadequate outgroups as the reason previous deep genomic-scale analyses found strong support for Coelomata.

Bilaterian phylogeny: a broad sampling of 13 nuclear genes provides a new Lophotrochozoa phylogeny and supports a paraphyletic basal acoelomorpha.

A new phylogeny not only agrees with most classical molecular results but also provides new insights into the relationships between lophotrochozoans and challenges the results obtained using high-throughput strategies, highlighting the problems associated with the current trend to increase gene number rather than taxa.

On the phylogenetic position of Myzostomida: can 77 genes get it wrong?

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.

Further use of nearly complete 28S and 18S rRNA genes to classify Ecdysozoa: 37 more arthropods and a kinorhynch.

100 Years of Deuterostomia (Grobben, 1908): Cladogenetic and Anagenetic Relations within the Notoneuralia Domain

The paper presented focuses on the chordate scenario, i.e. the hypothesis of an acrania-like ur-deuterostomian, and argues that the acranian-hypothesis is clearly preferable when biomechanic options of a polysegmented, hydroskeletal body plan are taken into account.

Phylogenomic analyses of lophophorates (brachiopods, phoronids and bryozoans) confirm the Lophotrochozoa concept

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.

MicroRNAs and phylogenomics resolve the relationships of Tardigrada and suggest that velvet worms are the sister group of Arthropoda

The study confirms the monophyly of the legged ecdysozoans, shows that past support for a Tardigrada + Nematoda group was due to long-branch attraction, and suggests that the velvet worms are the sister group to the arthropods.

A congruent solution to arthropod phylogeny: phylogenomics, microRNAs and morphology support monophyletic Mandibulata

The phylogenomic analyses strongly support Mandibulata, and show that Myriochelata is a tree-reconstruction artefact caused by saturation and long-branch attraction, and provide strong support for the inclusion of pycnogonids in a monophyletic Chelicerata, a paraphyletic Cycloneuralia, and a common origin of Arthropoda.



Systematic searches for molecular synapomorphies in model metazoan genomes give some support for Ecdysozoa after accounting for the idiosyncrasies of Caenorhabditis elegans

The results from the intensively sampled ribosomal RNA genes supporting the Ecdysozoa hypothesis provide the most credible current estimates of metazoan phylogeny, despite being biased toward grouping arthropods with chordates by systematic high rate of character loss in the nematode.

Early evolution of the bilateria.

Estimations of the divergence times show that the major bilaterian phyla did not originate in an explosive radiation during the Cambrian but rather that the Bilateria have a several hundred million years long Precambrian history.

Coelomata and not Ecdysozoa: evidence from genome-wide phylogenetic analysis.

A phylogenetic analysis of over 500 sets of orthologous proteins, which are represented in plants, animals, and fungi, using maximum likelihood, maximum parsimony, and distance methods showed concordance between evolution of protein sequences and higher-level evolutionary events, such as domain fusion or gene loss.

Fossil sister group of craniates: Predicted and found

Haikouella agrees so closely with recent predictions about pre‐craniates that the difficult problem of craniate origins is nearly solved.

Hox genes in brachiopods and priapulids and protostome evolution

It is shown that the complement of Hox genes in critical protostome phyla reflects these phylogenetic relationships and reveals the early evolution of developmental regulatory potential in bilaterians.

Phylogeny of eukaryotes based on ribosomal RNA: long-branch attraction and models of sequence evolution.

In this study, the complete large-subunit (LSU) rRNA of Trichomonas vaginalis is sequenced and it is shown that the late emergence of fast-evolving lineages such as the nucleomorph of chloroarachniophytes or microsporidia can be retrieved only when RAS models are assumed.

Evidence for a clade of nematodes, arthropods and other moulting animals

The results suggest that ecdysis (moulting) arose once and support the idea of a new clade, Ecdysozoa, containing moulting animals: arthropods, tardigrades, onychophorans, nematodes, Nematomorphs, kinor-hynchs and priapulids.

Evaluating hypotheses of deuterostome phylogeny and chordate evolution with new LSU and SSU ribosomal DNA data.

The rRNA-gene analysis refutes most of these hypotheses of deuterostome phylogeny that were constructed from morphological, embryological, and paleontological evidence and advocates a rethinking of chordate and vertebrate origins.

The earliest angiosperms: evidence from mitochondrial, plastid and nuclear genomes

This study demonstrates that Amboreella, Nymphaeales and Illiciales-Trimeniaceae-Austrobaileya represent the first stage of angiosperm evolution, with Amborella being sister to all other angiosperms, and shows that Gnetales are related to the conifers and are not sister to the angios perms, thus refuting the Anthophyte Hypothesis.

Can the Cambrian explosion be inferred through molecular phylogeny

It is observed that the major lines of triploblast coelomates (arthropods, molluscs, echinoderms, chordates...) are very poorly resolved i.e. the nodes defining the various clades are not supported by high bootstrap values.
