Acoel flatworms are small marine worms traditionally considered to belong to the phylum Platyhelminthes. However, molecular phylogenetic analyses suggest that acoels are not members of Platyhelminthes, but are rather extant members of the earliest diverging Bilateria. This result has been called into question, under suspicions of a long branch attraction (LBA) artefact. Here we re-examine this problem through a phylogenomic approach using 68 different protein-coding genes from the acoel…

Acoelomorph flatworms are deuterostomes related to Xenoturbella

This phylogeny makes sense of the shared characteristics of Xenoturbellida and Acoelomorpha, and implies the loss of various deuterostome characters in the Xenobiology including coelomic cavities, through gut and gill slits.

Acoelomorpha: earliest branching bilaterians or deuterostomes?

It is argued for the benefits of obtaining additional genomic data from acoelomorphs, in particular from taxa with slower evolutionary rates; the development of new tools to analyse the data; and the use of metagenomics or metatranscriptomics data to provide a definitive answer as to the position of the acoels in the animal tree of life.

Back in time: a new systematic proposal for the Bilateria

The phylogenetic trees obtained corroborate the position of acoel and nemertodermatid flatworms as the earliest branching extant members of the Bilateria and strengthen the view that stem bilaterians were small, acoELomate/pseudocoelomate, benthic organisms derived from planuloid-like organisms.

Molecular approaches for studying the evolution of the Xenacoelomorpha

Gen visualisation protocols are developed and applied to investigate the expression patterns of genes commonly associated with ultrafiltration in Xenoturbella and the acoel Symsagittifera roscoffensis to shed light on the origin and homology of filtratory structures, which remain unclear.

Xenoturbellida: The fourth deuterostome phylum and the diet of worms

The phylogenetic position for Xenoturbella is considered in the light of what is known of its genetics, morphology, and ontogeny and what light this might shine on the common ancestor of the deuterostomes and hence on the origins of the chordates.

Resolving lophotrochozoan phylogeny will provide important insight into how these complex and diverse body plans evolved and provide a much-needed framework for comparative studies.

The mysterious evolutionary origin for the GNE gene and the root of bilateria.

It is shown that GNE is encoded in the genomes of deuterostomes, acoelomorphs and Xenoturbella, whereas it is absent in protostomes and nonbilaterians and it is argued that rare genomic changes such as the one presented here should be used with caution.

The phylogenetic position of Acoela as revealed by the complete mitochondrial genome of Symsagittifera roscoffensis

The phylogenetic analysis supports the view that acoels and nemertodermatids are the earliest divergent extant lineage of Bilateria and remain a valid source for seeking primitive characters present in the last common ancestor of Bilatersia.

Phylogenomic evidence for separate acquisition of plastids in cryptophytes, haptophytes, and stramenopiles.

A phylogenomic falsification of the chromalveolate hypothesis that estimates signal strength across the three genomic compartments is devised, and the hypothesis is rejected as falsified in favor of more complex evolutionary scenarios involving multiple higher order eukaryotes-eukaryote endosymbioses.

An alternative view is discussed, in which acoelomorph flatworms, which do not belong to the Platyhelminthes, represent the earliest extant bilaterian clade, and this reconstruction backs the old planuloid–acoeloid hypothesis and may help the understanding of the evolution of body axes, Hox genes and the Cambrian explosion.

The Nemertodermatida are basal bilaterians and not members of the Platyhelminthes

The results imply that the last common ancestor of bilaterian metazoans was a small, benthic, direct developer without segments, coelomic cavities, nephrida or a true brain.

Tunicates and not cephalochordates are the closest living relatives of vertebrates

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.

Deuterostome phylogeny reveals monophyletic chordates and the new phylum Xenoturbellida

To study the relationships among all deuterostome groups, an alignment of more than 35,000 homologous amino acids is assembled, including new data from a hemichordate, starfish and Xenoturbella and it is concluded that chordates are monophyletic.

Combined large and small subunit ribosomal RNA phylogenies support a basal position of the acoelomorph flatworms

It is concluded that the Nemertodermatida and Acoela are basal bilaterians and, owing to their unique body plan and embryogenesis, should be recognized as a separate phylum, the Acoelomorpha.

Multigene analyses of bilaterian animals corroborate the monophyly of Ecdysozoa, Lophotrochozoa, and Protostomia.

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.

Is the Turbellaria polyphyletic?

A view consistent with the present evidence is to regard the Turbellaria (and hence the Platyhelminthes) as polyphyletic, consisting of three separate and unrelatable groups.

Mitochondrial genome data support the basal position of Acoelomorpha and the polyphyly of the Platyhelminthes.

A phylogenetic analysis of myosin heavy chain type II sequences corroborates that Acoela and Nemertodermatida are basal bilaterians

This study demonstrates that Platyhelminthes are polyphyletic and that acoels and nemertodermatids are the extant earliest bilaterians, and that the common bilaterian ancestor was not, as currently held, large and complex but small, simple, and likely with direct development.

The epidermal ciliary rootlets of Xenoturbella bocki (Xenoturbellida) revisited: new support for a possible kinship with the Acoelomorpha (Platyhelminthes)

The phylogenetic affinities of Xenoturbella remain highly debateable and a review of recent reports is given, together with a discussion of combinations of current phylogeny hypotheses.
