Recent molecular analyses indicate that crustaceans and hexapods form a clade (Pancrustacea or Tetraconata), but relationships among its constituent lineages, including monophyly of crustaceans, are controversial. [...] Key Result Our phylogenetic analysis of three protein–coding nuclear genes from 62 arthropods and lobopods (Onychophora and Tardigrada) demonstrates that Hexapoda is most closely related to the crustaceans Branchiopoda (fairy shrimp, water fleas, etc.) and Cephalocarida + Remipedia, thereby…Expand

Arthropod molecular divergence times and the Cambrian origin of pentastomids
TLDR
Bayesian phylogenetic and relaxed-clock analyses of molecular data help reconcile apparently contradictory views: a pentastomid-branchiuran grouping is recovered, but this clade is the sister group to other Tetraconata, whereas all other crustaceans form a monophyletic group that is sister to hexapods.
Molecular phylogenetic analyses support the monophyly of Hexapoda and suggest the paraphyly of Entognatha
TLDR
This is the first study to include all hexapod orders in a phylogenetic analysis using multiple nuclear protein-coding genes to investigate the phylogeny of Hexapoda, with an emphasis on Entognatha, and shows that Protura is the sister lineage to all other hexapods and that DiplURA or Diplura + Collembola is closely related to Ectognatha.
On the phylogenetic position of insects in the Pancrustacea clade
TLDR
Molecular synapomorphies in low homoplastic regions are reported, which support the clade Hexapoda + Branchiopoda + Maxillopoda and the monophyletic Malacostraca including Phyllocarida.
Pancrustacean phylogeny in the light of new phylogenomic data: support for Remipedia as the possible sister group of Hexapoda.
TLDR
This is the first time that a sister group relationship of Remipedia and Hexapoda has been inferred using a comprehensive phylogenomic data set that is based on EST data, and shows that selecting data subsets with increased overall signal can help to identify and prevent artifacts in phylogenetic analyses.

    Arthropod structure & development
  • 2010
TLDR
The basal node in the arthropod crown group is embroiled in a controversy over whether myriapods unite with chelicerates or with crustaceans and hexapods (Mandibulata), both groups find some molecular and morphological support, though MandibULata is presently the stronger morphological hypothesis.
Remarkable convergent evolution in specialized parasitic Thecostraca (Crustacea)
TLDR
Analysis of DNA sequences and DNA maximum likelihood and morphological-DNA Bayesian analysis trees indicate a convergent evolution of the very similar and highly reduced slug-shaped stages found during metamorphosis of both the Rhizocephala and the Facetotecta.
Pancrustacean Evolution Illuminated by Taxon-Rich Genomic-Scale Data Sets with an Expanded Remipede Sampling
TLDR
Mapping key crustacean tagmosis patterns and developmental characters across the revised phylogeny suggests that the ancestral pancrustacean was relatively short-bodied, with extreme body elongation and anamorphic development emerging later in pancrustACEan evolution.
The Pancrustacean Conundrum: A Conflicted Phylogeny with Emphasis on Crustacea
Pancrustacea represents a diverse clade of arthropods and includes the crustaceans and insects. The morphological and ecological diversity is among the most impressive of all invertebrates, with…
A new view of insect-crustacean relationships I. Inferences from neural cladistics and comparative neuroanatomy.
TLDR
The present study resolves branchiopod crustaceans as descendents of an ancestor with a complex brain, which means that they have evolved secondary simplification and the loss or reduction of numerous neural systems.
Phylogeny of Branchiopoda (Crustacea) - Character Evolution and Contribution of Uniquely Preserved Fossils
TLDR
A morphology-based phylogenetic analysis of Branchiopoda is presented, which combines recent taxa with the most well-preserved and informative fossils and provides a basis for a discussion of aspects of branchiopod evolution.

Phylogenetic position of the Pentastomida and (pan)crustacean relationships
TLDR
Gen arrangement comparisons strongly support an unforeseen assemblage of pentastomids with maxillopod and cephalocarid crustaceans, to the exclusion of remipedes, branchiopods, malacostracans and hexapods.
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.
Phylogeny of Basal Hexapod Lineages and Estimates of Divergence Times
TLDR
The analysis recovered a monophyletic Thysanura sensu lato (Archaeognatha + Zygentoma) as the sister group to Pterygota, a conclusion that is consistent with precladistic notions of hexapod systematics but conflicts with current understanding of morphological evolution.
Cambrian Derivatives of the Early Arthropod Stem Lineage, Pentastomids, Tardigrades and Lobopodians An ‘Orsten’ Perspective
TLDR
‘Orsten’-type preservation is the phosphatisation of cuticular surfaces without any further deformation and has yielded completely three-dimensional fossils, mainly arthropods at scale of 100 μm—2 mm, implying that the ancestry of Arthropoda lies even further back well in the Pre-Cambrian.
Crustacean phylogeny inferred from 18S rDNA
Resolution concerning issues of higher-order crustacean phylogeny remains elusive even after years of thorough morphological and palaeontological scrutiny. Surprisingly, there is as yet no consensus…
Arthropod Cladistics: Combined Analysis of Histone H3 and U2 snRNA Sequences and Morphology
TLDR
The most parsimonious trees based on 211 non‐sequence characters (273 apomorphic states) support traditional higher taxa as clades, including Mandibulata, Crustacea, Atelocerata, Myriapoda, and Hexapoda and monophyly of Chelicerata is maintained under a range of transition/transversion and third codon weights.
Molecular phylogenetics and the origins of placental mammals
TLDR
The potential weaknesses of limited character and taxon sampling are addressed in a comprehensive molecular phylogenetic analysis of 64 species sampled across all extant orders of placental mammals, providing new insight into the pattern of the early placental mammal radiation.
Elongation factor-2: a useful gene for arthropod phylogenetics.
TLDR
Elongation factor-2 is now the second protein-encoding, nuclear gene (in addition to RNA polymerase II) to support Pancrustacea over Atelocerata, and the discrepancy between results derived from molecular and morphological data deserves greater attention.
The fossil record 2
TLDR
This chapter discusses the main groups of the phylum Protozoa, which consists of Invertebrates, Amphibian-grade Tetrapoda, and Plants, and their relationships to each other.
Molecular evidence for inclusion of the phylum pentastomida in the crustacea
TLDR
Comparisons of nucleotide sequences of 18s ribosomal RNA from the pentastome Porocephalus crotali, the branchiuran crustacean fish louse Argulus nobilis, and representatives of the Annelida, Chelicerata, Myriapoda, and Insecta support an Argulus/PorocephaZus clade, providing strong support for the proposal that tongue worms are highly modified crustaceans closely related to fish lice.
