Traditional textbook phylogeny splits bilaterians into protostomes and deuterostomes according to whether their mouth derives from the blastopore or not. This scheme has been largely confirmed by small subunit ribosomal RNA (SSU) molecular phylogeny. However, some phyla, such as the lophphorate phyla Phoronida and Brachiopoda as well as the Chaetognatha exhibit classical deuterostome embryological features such as formation of the mesoderm from the gut (enterocoely) and secondary opening of the… Expand
Broad taxon and gene sampling indicate that chaetognaths are protostomes
TLDR
resolution of the phylogenetic position of the chaetognaths is key for reconstructing the evolutionary history of some of the most fundamental features of animals, including those that have been used to delineate two major clades of animals — the protostomes and deuterostomes. Expand
Spiralian phylogenomics supports the resurrection of Bryozoa comprising Ectoprocta and Entoprocta.
TLDR
The findings suggest that classical developmental and morphological key characters such as cleavage pattern, coelomic cavities, gut architecture, and body segmentation are subject to greater evolutionary plasticity than traditionally assumed. Expand
Phylogeny: The Continuing Classificatory Conundrum of Chaetognaths
TLDR
These analyses go some way towards defining the phylogenetic position of the chaetognaths, which possess features apparently spanning the protostome/deuterostome divide. Expand
The impact of mitochondrial genome analyses on the understanding of deuterostome phylogeny.
TLDR
Analysis of datasets comprising more than 300 complete deuterostome mitochondrial genomes revealed support for several relationships such as a basal position of Xenoturbella within Deuterostomia or for taxa like Craniota or Ambulacraria, but yielded also problems in some taxa, e.g. Tunicata, Pterobranchia and Ophiuroidea, due to long-branch artifacts.

Deuterostomic Development in the Protostome Priapulus caudatus
TLDR
Gastrulation and the embryonic expression of genes involved in bilaterian foregut and hindgut patterning in Priapulus caudatus are characterized and it is shown that the blastopore gives rise to the anus at the vegetal pole and that the hindgUT markers brachyury and caudal are expressed in the blastOPore and anus.

100 Years of Deuterostomia (Grobben, 1908): Cladogenetic and Anagenetic Relations within the Notoneuralia Domain
TLDR
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. Expand
Acoel Flatworms Are Not Platyhelminthes: Evidence from Phylogenomics
TLDR
A phylogenomic approach using 68 different protein-coding genes from the acoel Convoluta pulchra and 51 metazoan species belonging to 15 different phyla shows that acoels are not part of the classically defined Platyhelminthes, making the latter polyphyletic. Expand
Rotiferan Hox genes give new insights into the evolution of metazoan bodyplans
TLDR
The expression of five Hox genes are reported during embryogenesis of the rotifer Brachionus manjavacas and it is shown how these genes define different functional components of the nervous system and not the usual bilaterian staggered expression along the anteroposterior axis. Expand
Introduction to the Bilateria and the Phylum Xenacoelomorpha Triploblasty and Bilateral
TLDR
The invention of a third (middle) germ layer, the true mesoderm, and evolution of a bilateral body plan, opened up vast new avenues for evolutionary expansion among animals. Expand
Lophotrochozoa internal phylogeny: new insights from an up-to-date analysis of nuclear ribosomal genes
TLDR
Ribosomal RNA genes are considered a reliable source for the study of deep divergences in the metazoan tree, provided that the data are treated carefully and the LBA effect is minimized. Expand

Evidence from 18S ribosomal DNA that the lophophorates are protostome animals
TLDR
Sequence analyses show that lophophorates are protostomes closely related to mollusks and annelids, which deviates from the commonly held view of deuterostome affinity. Expand
Broad taxon and gene sampling indicate that chaetognaths are protostomes
TLDR
resolution of the phylogenetic position of the chaetognaths is key for reconstructing the evolutionary history of some of the most fundamental features of animals, including those that have been used to delineate two major clades of animals — the protostomes and deuterostomes. Expand
Identification of chaetognaths as protostomes is supported by the analysis of their mitochondrial genome.
TLDR
The complete mitochondrial DNA genome of Spadella cephaloptera is determined, it is the smallest metazoan mitochondrial genome known and lacks both atp8 and atp6 and all tRNA genes, and phylogenetic reconstructions show that Chaetognatha belongs to protostomes. Expand
The phylogenetic affinities of the chaetognaths: a molecular analysis.
TLDR
This work proposes that the lineage leading to the chaetognaths arose prior to the advent of the coelomate metazoa, and isolation and nucleotide sequence determination of 18S ribosomal DNA from one species of Chaetognath and one acanthocephalan are described. Expand
Multigene analyses of bilaterian animals corroborate the monophyly of Ecdysozoa, Lophotrochozoa, and Protostomia.
TLDR
This study demonstrates that the incongruences observed between rRNA and multigene analyses were indeed due to long-branch attraction artifacts, illustrating the enormous impact of systematic biases on phylogenomic studies and suggests that urochordates are more closely related to vertebrates than are cephalochordates. Expand
Phylogenomics and the reconstruction of the tree of life
TLDR
This work has demonstrated the power of the phylogenomics approach, which has the potential to provide answers to several fundamental evolutionary questions, but challenges for the future have also been revealed. Expand
Coelomata and not Ecdysozoa: evidence from genome-wide phylogenetic analysis.
TLDR
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. Expand
Tunicates and not cephalochordates are the closest living relatives of vertebrates
TLDR
It is shown that phylogenetic analyses of the genome sequencing of the appendicularian Oikopleura dioica provide compelling evidence that tunicates, and not cephalochordates, represent the closest living relatives of vertebrates. Expand
Animal Evolution and the Molecular Signature of Radiations Compressed in Time
TLDR
The phylogenetic relationships among most metazoan phyla remain uncertain, but the differences in resolution within the two kingdoms suggest that the early history of metazoans was a radiation compressed in time, a finding in agreement with paleontological inferences. Expand
EST Analysis of the Cnidarian Acropora millepora Reveals Extensive Gene Loss and Rapid Sequence Divergence in the Model Invertebrates
TLDR
Gene loss has been much more extensive in the model invertebrate lineages than previously assumed and, as a consequence, some genes formerly thought to be vertebrate inventions must have been present in the common metazoan ancestor. Expand
