Long-held ideas regarding the evolutionary relationships among animals have recently been upended by sometimes controversial hypotheses based largely on insights from molecular data. These new hypotheses include a clade of moulting animals (Ecdysozoa) and the close relationship of the lophophorates to molluscs and annelids (Lophotrochozoa). Many relationships remain disputed, including those that are required to polarize key features of character evolution, and support for deep nodes is often… Expand

Assessing the root of bilaterian animals with scalable phylogenomic methods
  • A. Hejnol, M. Obst, +14 authors C. Dunn
  • Biology, Medicine
  • Proceedings of the Royal Society B: Biological Sciences
  • 2009
TLDR
New sequence data and methods strongly uphold previous suggestions that Acoelomorpha is sister clade to all other bilaterian animals, find diminishing evidence for the placement of the enigmatic Xenoturbella within Deuterostomia, and place Cycliophora with Entoprocta and EctoproCTa. Expand
A phylogenomic approach to resolve the arthropod tree of life.
TLDR
It is shown that phylogenomic data can substantially advance the understanding of arthropod evolution and resolve several conflicts among existing hypotheses. 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
Testing the new animal phylogeny: a phylum level molecular analysis of the animal kingdom.
TLDR
The data show strong support for the basic structure of the new animal phylogeny as well as for the Mandibulata including Myriapoda, and some resolution within the Lophotrochozoa is provided. Expand
Phylogeny of Animals: Genomes Have a Lot to Say
TLDR
This work has triggered several advances regarding metazoan relationships such as the reevaluation of chordate relationships and the re-positioning of some problematic minor phyla with improved accuracy, and raised new questions about the processes that underlie morphological evolution, as well as the future of molecular phylogenetics. Expand
Genomics and the animal tree of life: conflicts and future prospects
TLDR
This work discusses some of the major controversies and poorly resolved deep nodes still remain in the animal tree of life, and explores the meaning of total support in phylogenomic analyses, highlighting cases in which a data set can provide total support for contradictory nodes. Expand
Insect Phylogenomics: Exploring the Source of Incongruence Using New Transcriptomic Data
TLDR
Based on the first phylogenomic approach including these three ambiguous polyneopteran orders, conclusive support for monophyletic Polyneoptera is provided, contesting the hypothesis of Zoraptera + Paraneoptera and Plecoptera + remaining Neoptera. Expand
Revisiting metazoan phylogeny with genomic sampling of all phyla
TLDR
The first attempt to investigate animal relationships using genome-scale data from all phyla is presented, and matrix construction with an eye towards testing specific relationships is explored, showing that Lophotrochozoa can be constructed in strongly conflicting ways using different taxon- and/or orthologue sets. Expand
Improved Phylogenomic Taxon Sampling Noticeably Affects Nonbilaterian Relationships
TLDR
This work recovers monophyletic Porifera as the sister group to all other Metazoa and suggests that the basal position of the fast-evolving Ctenophora proposed by Dunn et al. was due to LBA and that broad taxon sampling is of fundamental importance to metazoan phylogenomic analyses. Expand
Evidence for sponges as sister to all other animals from partitioned phylogenomics with mixture models and recoding
TLDR
It is shown that incorporating site-heterogeneous mixture models and recoding into partitioned phylogenomics alleviates systematic errors that hamper commonly-applied phylogenetic models and improves model-fit that attenuates branching artefacts induced by systematic error. Expand

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
Phylogenomics of eukaryotes: impact of missing data on large alignments.
TLDR
This large data set provides a reliable phylogenetic framework for studying eukaryotic and animal evolution and will be easily extendable when large amounts of sequence information become available from a broader taxonomic range. Expand
THE NEW VIEW OF ANIMAL PHYLOGENY
■ Abstract Molecular tools have profoundly rearranged our understanding of metazoan phylogeny. Initially based on the nuclear small ribosomal subunit (SSU or 18S) gene, recent hypotheses have been… 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
Arthropod phylogeny based on eight molecular loci and morphology
TLDR
The optimal ‘total evidence’ cladogram supports the crustacean–hexapod clade, recognizes pycnogonids as sister to other euarthropods, and indicates monophyly of Myriapoda and Mandibulata. Expand
Lack of resolution in the animal phylogeny: closely spaced cladogeneses or undetected systematic errors?
TLDR
This work proposes that the animal phylogeny was unresolved despite the use of 50 genes is due to the mutual cancellation of the phylogenetic signal and the nonphylogenetic signal that results from inadequate taxon sampling and/or model of sequence evolution. Expand
Mitochondrial protein phylogeny joins myriapods with chelicerates
TLDR
Molecular phylogenetic analysis of conserved regions from the arthropod mitochondrial proteome yields highly resolved and congruent trees and proposes a model to explain the apparently parallel evolution of similar head morphologies in insects and myriapods. Expand
The Opisthokonta and the Ecdysozoa may not be clades: stronger support for the grouping of plant and animal than for animal and fungi and stronger support for the Coelomata than Ecdysozoa.
TLDR
This work constructed phylogenetic trees from 780 single-gene families from 10 completed genomes and amalgamated these into a single supertree and found that the evolution of intron gain and loss in the rpL14 gene is much more compatible with the hypothesis presented here than with the Opisthokonta hypothesis. Expand
Ecdysozoan phylogeny and Bayesian inference: first use of nearly complete 28S and 18S rRNA gene sequences to classify the arthropods and their kin.
TLDR
Better taxonomic resolution and recovery of established taxa were obtained here, especially with Bayesian inference, than in previous parsimony-based studies that used 18S rRNA sequences, and should revive interest in using rRNA genes to study arthropod and ecdysozoan relationships. Expand
The evolutionary position of nematodes
TLDR
Insects (arthropods) are genetically and evolutionarily closer to humans than to nematode worms, and the Ecdysozoa hypothesis is not supported. Expand
