THE origins of arthropods and the phylogenetic relationships among their three major living groups (atelocerates, crustaceans and chelicerates) are vigorously contended. To help resolve this, we determined mitochondrial gene arrangements for a chelicerate, a myriapod, two crustaceans, an onychophoran, a mollusc and an annelid, and compared them with published gene orders of other species. The result strongly supports the monophyly of Arthropoda and of Mandibulata (atelocerates plus crustaceans… 

A molecular phylogeny of the bivalve mollusks.

A phylogenetic reconstruction based on 506 nucleotides near the 5' end of the 18S subunit of ribosomal DNA (rDNA) in 2 gastropod, 3 chiton and 28 bivalve mollusks could not confidently establish either the monophyly or the phylogenetic relationships of the morphologically well defined subclasses Pteriomorphia, Protobranchia, and Anomalodesmata.

The mitochondrial genome of the Sipunculid Phascolopsis gouldii supports its association with Annelida rather than Mollusca.

Comparison of both the inferred amino acid sequences and the gene arrangements of a variety of diverse metazoan taxa reveals that the phylum Sipuncula is more closely related to Annelida than to Mollusca.

The mitochondrial genome of Phoronis architecta--comparisons demonstrate that phoronids are lophotrochozoan protostomes.

The proper reconstruction of the relationships among the animal phyla is central to interpreting patterns of animal evolution from the genomic level to the morphological level. This is true not only

DNA sequence analysis to study the evolution of Antarctic Collembola

Abstract The mitochondrial COII gene was shown to be a useful marker at the population level in Isotoma klovstadi, and for studying phylogenetic relationships at the family level, while the nuclear

Mitochondrial gene arrangement of the horseshoe crab Limulus polyphemus L.: conservation of major features among arthropod classes.

High degree of similarity of mitochondrial gene arrangements within arthropods is striking, since some taxa last shared a common ancestor before the Cambrian, and contrasts with the extensive mtDNA rearrangements occasionally observed within some other metazoan phyla.

Poriferan mtDNA and animal phylogeny based on mitochondrial gene arrangements.

This work determined complete mitochondrial DNA sequences for the demosponges Geodia neptuni and Tethya actinia, two representatives of the most basal animal phylum, the Porifera, and provides strong support for a group that includes protostome (but not deuterostome) coelomate, pseudocoelomates, and acoelomating animals, thus clearly rejecting the Coelomata hypothesis.

Investigation of molluscan phylogeny on the basis of 18S rRNA sequences.

These data do not provide support for a close relationship between Platyhelminthes (Turbellaria) and Mollusca, but suggest that the latter group belongs to a clade of eutrochozoan coelomates, and obtain strong preliminary support for phylogenetic inferences at more restricted taxonomic levels.

What genes and chromosomes say about the origin and evolution of insects and other arthropods

The presence of the specific telomeric motif TTAGG confirmed the monophyletic origin of arthropods (Arthropoda) and the assignment of tongue worms (Pentastomida) to this type.

Gene translocation links insects and crustaceans

A derived gene rearrangement common to insects and crustaceans but absent in the other arthropod groups is reported, suggesting an insect-crustacean evolutionary lineage that is separate from those leading to myriapods and chelicerates.



Evidence from 12S ribosomal RNA sequences that onychophorans are modified arthropods.

Parsimony analysis suggests that onychophorans form a sister group to chelicerates and crustaceans plus hexapods, but this relationship is not well supported by monophyly testing, which conflict with current hypotheses of evolutionary pathways within arthropods.

Molecular phylogeny of the animal kingdom.

A rapid sequencing method for ribosomal RNA was applied to the resolution of evolutionary relationships among Metazoa, finding that coelomates radiated rapidly into four groups: chordates, echinoderms, arthropods, and eucoelomate protostomes.

Analysis of rate invariant analysis of 18S rRNA sequences indicates that the Metazoa is a monophyletic taxon, and the Annelida-Mollusca lineage is the sister group of an arthropod subgroup.


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.

Arthropod Phylogeny with Special Reference to Insects

Elucidates the major evolutionary pathways of the Phylum Arthropoda, based on the phylogenetic method of Hennig, and focuses on discovering the derived character states that most probably had a common origin in an ancestral state.

Sequence evolution in mitochondrial ribosomal and ND-1 genes in lepidoptera: implications for phylogenetic analyses.

Inability of molecular data to recover a well-established phylogeny may be rectified by additional characters or taxa, but it is clear that homoplasy is sufficiently high to caution against the acceptance of relationships generated with this molecular region that are not extremely robust.

The primary structure of the 18S rRNA of the bird spider Eurypelma californica has been determined in the framework of a study of metazoan phylogeny on the basis of ribosomal RNA structure. A

Congruence Between Molecular and Morphological Phylogenies

Phylogenies based on molecular sequence data and on morphology are surveyed and compared within animals and within plants and it is found that incongruence between molecular trees (generated from different data sets or by different analytical methods) is as striking or pervasive as is incongrience between trees generated by morphologists in the long history of their discipline.
