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… 
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.
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.
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.
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.
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.
Improved resolution of recalcitrant nodes in the animal phylogeny through the analysis of genome gene content and morphology
TLDR
The last common animal ancestor may has been a simple, filter-feeding organism without a nervous system and muscles, while the last common ancestor of Bilateria might have been a small, acoelomate-like worm without a through gut.
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.
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.
Putting Animals in their Place within a Context of Eukaryotic Innovations
TLDR
The current understanding of animal evolutionary relationships is reviewed, including which of the basal metazoan phyla (Porifera, Placozoa, Cnidaria, or Ctenophora) is basal-most, the branching order of the three major lineages of Arthropoda, the relationships within Lophotrochozoa, and the placement of several so-called minor groups such as Chaetognatha.
Animal Phylogeny and Its Evolutionary Implications
TLDR
There is far more homoplasy for all these characters than had previously been anticipated, even among many complex characters such as segmentation and nervous systems, which has important implications for the understanding of the evolution of development, morphology, genomes, and other characters.

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.
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.
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.
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.
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.
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.
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.
Evidence for a clade composed of molluscs with serially repeated structures: Monoplacophorans are related to chitons
TLDR
The first molecular data on monoplacophorans, analyzed together with the largest data set of molluscs ever assembled, clearly illustrate that monoplacs and chitons form a clade and may have important implications for metazoan evolution.
Consideration of RNA secondary structure significantly improves likelihood-based estimates of phylogeny: examples from the bilateria.
TLDR
A novel permutation approach is used to demonstrate the significant superiority of models of sequence evolution that allow stem and loop regions to evolve according to separate models and it is shown that 16-state models that take base pairing of stems into account are significantly better than simpler, 4-state, single-nucleotide models.
