Arthropod relationships revealed by phylogenomic analysis of nuclear protein-coding sequences
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.

A Bayesian statistical estimate of divergence times suggests a Precambrian origin for Pancrustacea (600 Myr ago or more), which precedes the first unambiguous arthropod fossils by over 60 Myr. Expand

The results corroborate the broad outlines of the current working phylogenetic hypothesis for Ditrysia, demonstrate that some prominent features of that hypothesis, including the position of the butterflies, need revision, and resolve the majority of family and subfamily relationships within superfamilies as thus far sampled.

A highly conserved nuclear gene for low-level phylogenetics: elongation factor-1 alpha recovers morphology-based tree for heliothine moths.
This postulate that the single most parsimonious gene tree and the neighbor-joining tree for all nucleotides show almost complete concordance with the morphological tree for the EF-1 alpha gene in the noctuid moth subfamily Heliothinae is tested. Expand
Resolving arthropod phylogeny: exploring phylogenetic signal within 41 kb of protein-coding nuclear gene sequence.
This study attempts to resolve relationships among and within the four basal arthropod lineages and to assess the widespread expectation that remaining phylogenetic problems will yield to increasing amounts of sequence data. Expand
A Large-Scale, Higher-Level, Molecular Phylogenetic Study of the Insect Order Lepidoptera (Moths and Butterflies)
This study highlights the challenge of finding optimal topologies when analyzing hundreds of taxa and shows that some nodes get strong support only when analysis is restricted to nonsynonymous change, while total change is necessary for strong support of others. Expand
Phylogenetic analysis of Myriapoda using three nuclear protein-coding genes.
The results of the present study indicate that taxon sample and sequence length alone do not readily explain the weakly supported resolution in the earlier study, which indicates that heterogeneity in phylogenetic signal provided by the authors' slowly evolving sequences is due to heterogeneity in the temporal structure of myriapod diversification. Expand
Molecular phylogeny of the major arthropod groups indicates polyphyly of crustaceans and a new hypothesis for the origin of hexapods.
A phylogeny of the arthropods was inferred from analyses of amino acid sequences derived from the nuclear genes encoding elongation factor-1 alpha and the largest subunit of RNA polymerase II using maximum-parsimony, neighbor-joining, and maximum-likelihood methods, providing support for a Hexapoda/Branchiopoda clade, thus arguing against the monophyly of the traditionally defined Atelocerata.

Phylogenetic analysis of arthropods using two nuclear protein–encoding genes supports a crustacean + hexapod clade
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.

Systematics and evolution of the cutworm moths (Lepidoptera: Noctuidae): evidence from two protein‐coding nuclear genes
Mapping of a preliminary synopsis of species diversities, host use patterns and latitudinal distributions on the phylogeny suggests that the diversification of trifines may have been promoted, to a degree unique among Macrolepidoptera, by the Tertiary expansion of seasonal, open habitats and their associated herbaceous floras.
