  • Beschreibung: <jats:title>Ocean Dweller Sequenced</jats:title> <jats:p> The Tunicates, which include the solitary free-swimming larvaceans that are a major pelagic component of our oceans, are a basal lineage of the chordates. In order to investigate the major evolutionary transition represented by these organisms, <jats:bold> Denoeud <jats:italic>et al.</jats:italic> </jats:bold> (p. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" page="1381" related-article-type="in-this-issue" vol="330" xlink:href="10.1126/science.1194167">1381</jats:related-article> , published online 18 November) sequenced the genome of <jats:italic>Oikopleura dioica</jats:italic> , a chordate placed by phylogeny between vertebrates and amphioxus. Surprisingly, the genome showed little conservation in genome architecture when compared to the genomes of other animals. Furthermore, this highly compacted genome contained intron gains and losses, as well as species-specific gene duplications and losses that may be associated with development. Thus, contrary to popular belief, global similarities of genome architecture from sponges to humans are not essential for the preservation of ancestral morphologies. </jats:p>
