Arthropod relationships revealed by phylogenomic analysis of nuclear protein-coding sequences
The remarkable antiquity, diversity and ecological significance of arthropods have inspired numerous attempts to resolve their deep phylogenetic history, but the results of two decades of intensive… Expand
Ecdysozoan phylogeny and Bayesian inference: first use of nearly complete 28S and 18S rRNA gene sequences to classify the arthropods and their kin.
Relationships among the ecdysozoans, or molting animals, have been difficult to resolve. Here, we use nearly complete 28S+18S ribosomal RNA gene sequences to estimate the relations of 35 ecdysozoan… Expand
Pancrustacean phylogeny: hexapods are terrestrial crustaceans and maxillopods are not monophyletic

- 22 February 2005
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… Expand
EVOLUTIONARY MORPHOLOGY AND PHYLOGENY OF ARAGHNIDA
- J. Shultz
- 1 March 1990
Abstract— This paper reports results from a cladistic analysis of the 11 Recent arachnid orders. The polarities of 64 newly discovered and traditional characters were determined through outgroup… 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 (Pancrustacea, Myriapoda, Euchelicerata, Pycnogonida) and to assess the widespread expectation that… Expand
Phylogenetic analysis of Myriapoda using three nuclear protein-coding genes.
We assessed the ability of three nuclear protein-encoding genes-elongation factor-1alpha (EF-1alpha), RNA polymerase II (Pol II), and elongation factor-2 (EF-2)-from 59 myriapod and 12 non-myriapod… Expand
Morphology of locomotor appendages in Arachnida: evolutionary trends and phylogenetic implications
- J. Shultz
- 1 September 1989
The morphological diversity of locomotor appendages in Arachnida is surveyed lo reconstruct phylogenetic relationships and discover evolutionary trends in form and function. The appendicular skeleton… 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… Expand
Phylogenetic analysis of arthropods using two nuclear protein–encoding genes supports a crustacean + hexapod clade
Recent phylogenetic analyses using molecular data suggest that hexapods are more closely related to crustaceans than to myriapods, a result that conflicts with long–held morphology–based hypotheses.… Expand
PHYLOGENETIC ANALYSIS OF PHALANGIDA (ARACHNIDA, OPILIONES) USING TWO NUCLEAR PROTEIN-ENCODING GENES SUPPORTS MONOPHYLY OF PALPATORES
Abstract Recent phylogenetic studies of Opiliones have shown that Cyphophthalmi and Phalangida (= Palpatores + Laniatores) are sister groups, but higher relationships within Phalangida remain… Expand
