Sponges (phylum Porifera) are a diverse taxon of benthic aquatic animals of great
ecological, commercial, and biopharmaceutical importance. They are arguably the earliest-branching …

In the quest to reconstruct the Tree of Life, researchers have increasingly turned to
phylogenomics, the inference of phylogenetic relationships using genome-scale data (Box 1). …

The evolutionary relationships among the four major lineages of arthropods remain
controversial, despite extensive study. We report here a derived gene rearrangement common to …

We determined the complete mtDNA sequence of the centipede Lithobius forficatus and
found that only one of the 22 inferred tRNA genes encodes a fully paired aminoacyl acceptor …

We determined the complete mitochondrial DNA (mtDNA) sequences of the millipedes Narceus
annularus and Thyropygus sp. (Arthropoda: Diplopoda) and identified, in both genomes, …

We sequenced the nearly complete mtDNA of 3 species of parasitic wasps, Nasonia
vitripennis (2 strains), Nasonia giraulti, and Nasonia longicornis, including all 13 protein-coding …

… by pentastomid and nematode mtDNAs (Lavrov 2001), we are reluctant to overemphasize
this … Lavrov, DV 2001 Arthropod phylogeny based on gene arrangement and other characters …

Background Cnidaria (corals, sea anemones, hydroids, jellyfish) is a phylum of relatively
simple aquatic animals characterized by the presence of the cnidocyst: a cell containing a giant …

We determined the complete 14,985-nt sequence of the mitochondrial DNA of the horseshoe
crab Limulus polyphemus (Arthropoda: Xiphosura). This mtDNA encodes the 13 protein, 2 …

The complete mitochondrial DNA (mtDNA) of the nematode Trichinella spiralis has been
amplified in four overlapping fragments and 16,656 bp of its sequence has been determined. …
