The interrelationships of major clades within the Arthropoda remain one of the most contentious issues in systematics, which has traditionally been the domain of morphologists. A growing body of DNA sequences and other types of molecular data has revitalized study of arthropod phylogeny and has inspired new considerations of character evolution. Novel hypotheses such as a crustacean–hexapod affinity were based on analyses of single or few genes and limited taxon sampling, but have received… Expand
Arthropod phylogeny revisited, with a focus on crustacean relationships.
TLDR
A preliminary attempt to incorporate the large diversity of crustaceans into a single molecular phylogenetic analysis, assessing the robustness of phylogenetic relationships under varying analysis parameters and providing useful pointers for future studies. 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
Phylogenetic analysis of mitochondrial protein coding genes confirms the reciprocal paraphyly of Hexapoda and Crustacea
TLDR
The finding of the reciprocal paraphyly of Hexapoda and Crustacea suggests an evolutionary scenario in which the acquisition of the hexapod condition may have occurred several times independently in lineages descending from different crustacean-like ancestors, possibly as a consequence of the process of terrestrialization. Expand
The phylogenetic position of early hexapod lineages: morphological data contradict molecular data
TLDR
It appears that in the present state of the analytical strategies, hypotheses concerning arthropod phylogenies obtained from morphological and developmental criteria and combined analyses involving molecular and morphological data provide more reliable results than those generated by molecular information alone. Expand
A review of molecular data for the phylogeny of basal hexapods
TLDR
This paper reviews the major contributions to the phylogeny of hexapods based on molecular data, with emphasis on the relationships of basal hexapod taxa. Expand
Molecular phylogeny of the Calanoida (Crustacea: Copepoda).
TLDR
This study establishes a multi-gene molecular phylogeny of the calanoid copepods based upon small (18S) and large (28S) subunits of nuclear ribosomal RNA genes and mitochondrial encoded cy tochrome b and cytochrome c oxidase subunit-I genes, including 29 families from 7 superfamilies of the order.

On bivalve phylogeny: a high‐level analysis of the Bivalvia (Mollusca) based on combined morphology and DNA sequence data
Abstract. Bivalve classification has suffered in the past from the crossed-purpose discussions among paleontologists and neontologists, and many have based their proposals on single characterExpand
Arthropod relationships revealed by phylogenomic analysis of nuclear protein-coding sequences
TLDR
This work presents strongly supported results from likelihood, Bayesian and parsimony analyses of over 41 kilobases of aligned DNA sequence from 62 single-copy nuclear protein-coding genes from 75 arthropod species, providing a statistically well-supported phylogenetic framework for the largest animal phylum. Expand
Phylogenomic interrogation of arachnida reveals systemic conflicts in phylogenetic signal.
TLDR
It is shown that phylogenetic signal for the monophyly of Arachnida is restricted to the 500 slowest-evolving genes in the data set, and that outgroup selection without regard for branch length distribution exacerbates long-branch attraction artifacts and does not mitigate gene-tree discordance, regardless of high gene representation for outgroups that are model organisms. Expand
The colonization of land by animals: molecular phylogeny and divergence times among arthropods
TLDR
The consistent support for a close relationship between myriapods and chelicerates, using mitochondrial and nuclear genes and different methods of analysis, suggests that arthropods may have adapted to the terrestrial environment relatively late in their evolutionary history. Expand

Ribosomal DNA phylogeny of the major extant arthropod classes and the evolution of myriapods
TLDR
Using nuclear ribosomal gene sequences for constructing a molecular phylogeny, this work provides strong evidence that the crustaceans and not the myriapods should be considered to be the sister group of the insects. Expand
Mitochondrial Genes Collectively Suggest the Paraphyly of Crustacea with Respect to Insecta
TLDR
A phylogenetic analysis using amino acid sequences of the seven corresponding polypeptides supports a sister-taxon status for mollusks–annelid and arthropods and suggests that crustaceans are paraphyletic with respect to insects. Expand
Hox genes and the phylogeny of the arthropods
TLDR
The data support the hypothesis that insects and crustaceans form a single clade within the arthropods to the exclusion of myriapods and suggest that myriAPods are more closely allied to the chelicerates than to this insect/crustacean clade. Expand
Phylogenetic analysis of arthropods using two nuclear protein–encoding genes supports a crustacean + hexapod clade

TLDR
Results from maximum–parsimony and maximum–likelihood analyses strongly supported the existence of a Crustacea+ Hexapoda clade (Pancrustacea) over a Myriapoda + Hexapod clade(s) (Atelocerata) and the apparent incompatibility between the molecule–based Pancrustacea hypothesis and morphology–based AtelOCerata hypothesis is discussed.

Molecular Phylogeny of Arthropods and the Significance of the Cambrian “Explosion” for Molecular Systematics
TLDR
Two models are proposed to explain incongruity in the attempt to resolve arthropod phylogeny using the amino acid sequence of elongation factor-1α, which fails to establish relationships among most higher-level groups, although it does recover more recently derived clades. Expand
First molecular evidence for the existence of a Tardigrada + Arthropoda clade.
TLDR
The results obtained represent the first molecular evidence for a Tardigrada + Arthropoda clade and indicate the need to review those obtained solely on morphological characters. Expand
Histone H3 and U2 snRNA DNA sequences and arthropod molecular evolution
TLDR
Combined (‘spliced’) analysis of both genes improves topological congruence with morphological groupings relative to that of either partition, suggesting that the class of snRNAs may provide several phylogenetically useful genes. Expand
ARTHROPOD PHYLOGENY: A COMBINED APPROACH
TLDR
Ribosomal and ubiquitin protein coding sequence data are generated from 20 arthropods and five close relatives combined with morphological characters derived from the literature to approach arthropod phylogenetics from the perspective of total evidence. Expand
Evidence for a clade of nematodes, arthropods and other moulting animals
TLDR
The results suggest that ecdysis (moulting) arose once and support the idea of a new clade, Ecdysozoa, containing moulting animals: arthropods, tardigrades, onychophorans, nematodes, Nematomorphs, kinor-hynchs and priapulids. Expand
A Review of Arthropod Phylogeny: New Data Based on Ribosomal DNA Sequences and Direct Character Optimization
TLDR
The high level of sequence heterogeneity in the 18S rRNA gene makes placement of certain taxa with “unusual” sequences difficult and underscores the necessity of combining ribosomal gene data with other sources of information. Expand
