The first hypothesis corresponds to the traditional grouping Coelomata and the second corresponds to Ecdysozoa [ 3 ] . For convenience, we will use these names in reference to the two hypotheses while recognizing that this study, by necessity, involves only a subset of all animal phyla.
The 16S rRNA based phylogenetic tree (Figure 1) generally matched the accepted 16S rRNA model with clear separation of the two prokaryotic domains and the subsequent divergence of Eukarya (represented by Saccharomyces cerevisiae ) from Archaea [ 31 ] . Minor inconsistencies such as Ralstonia solanacearum (β-Proteobacteria) forming a deep branch within the γ-Proteobacteria, or Fusobacterium nucleatum (Fusobacteria) and Leptospira interrogans (Spirochetes) grouping loosely with the Gram-positive Bacteria are likely the result of the limited data set used (they were the only representatives of their respective phyla that had listed arsC genes) and do not challenge established relationships.
, nematodes) with a false coelom and finally to the bulk of animal phyla having a true coelom (Coelomata) [ 1 2 ] . There has never been complete agreement on animal phylogeny and classification, but most researchers have divided living coelomate animals into deuterostomes (echinoderms, hemichordates, urochordates, cephalochordates, and vertebrates) and protostomes (arthropods, annelids, mollusks, and other phyla) based on differences in early embryonic development.
An analysis of small subunit ribosomal RNA (18S rRNA) sequences challenged this arrangement by placing acoelomate and pseudocoelomate phyla in more derived positions among the protostomes, and in further defining a clade (Ecdysozoa) of molting animals that includes arthropods and nematodes [ 3 ] . This "Ecdysozoa" hypothesis has influenced diverse fields [ 4 ] and interpretations of developmental evolution in animals [ 5 6 7 ] . Since its publication, evidence has appeared both for and against this hypothesis [ 8 9 10 11 12 13 14 15 ] . Knowing the branching order of the major animal lineages, especially those three with fully sequenced genomes, is of importance to diverse fields such as medical genetics, physiology, neurobiology, paleontology, and astrobiology.
A writer catalogs the six phyla of screen aliens, which include "the small, gray, hairless, chinless, big-eyed waif" à la Close Encounters and "the comic-relief plush toy" such as Alf.
