Background Since the drastic reorganisation of the phylogeny of the animal kingdom into three major clades of bilaterians; Ecdysozoa, Lophotrochozoa and Deuterostomia, it became glaringly obvious that the selection of model systems with extensive ...

Rare Coding Sequence Changes are Consistent with Ecdysozoa, not Coelomata [PDF]
There is growing interest in the use of alternative, more slowly-evolving RGCs (rare genomic changes). Recently, Rogozin and coauthors (Rogozin et al. 2007) proposed a novel phylogenetic method employing rare amino acid changes, RGC-CAMs (rare genomic changes-conserved amino acids-multiple substitutions).

Background To understand the evolution of animals it is essential to have taxon sampling across a representative spread of the animal kingdom. With the recent rearrangement of most of the Bilateria into three major clades (Ecdysozoa, Lophotrochozoa and ...

Peripheral and central employment of acid-sensing ion channels during early bilaterian evolution
Nervous systems are endowed with rapid chemosensation and intercellular signaling by ligand-gated ion channels (LGICs). While a complex, bilaterally symmetrical nervous system is a major innovation of bilaterian animals, the employment of specific LGICs ...

Background It is hypothesised that being a blood-feeding ectoparasite, Argulus foliaceus (Linnaeus, 1758), uses similar mechanisms for digestion and host immune evasion to those used by other haematophagous ecdysozoa, including caligid copepods (e.g. sea

The Ecdysozoa: Artifact or monophylum?
The molecular support for the recently postulated hypothesis ‘Ecdysozoa’ is re-examined. Some 18S rDNA-alignments clearly contain a pattern of character states that cause tree building methods to identify a clade comprised of arthropods and Cycloneuralia.

Growth and Maintenance of Wolbachia in Insect Cell Lines
The obligate intracellular microbe, Wolbachia pipientis (Rickettsiales; Anaplasmataceae), is a Gram-negative member of the alpha proteobacteria that infects arthropods and filarial worms.

Background Tardigrada is a group of microscopic invertebrates distributed worldwide in permanent and temporal aquatic habitats. Famous for their extreme stress tolerance, tardigrades are also of interest due to their close relationship with Arthropoda ...

The Natural History of Teneurins: A Billion Years of Evolution in Three Key Steps
The entire evolutionary history of the animal gene family, Teneurin, can be summed up in three key steps, plus three salient footnotes. In a shared ancestor of all bilaterians, the first step began with gene fusions that created a protein with an amino ...
