This worm is not for turning
Article Abstract:
Molecular investigations of the origin of the dorso-ventral axis in an obscure marine invertebrate over the origin of vertebrates is discussed by taking an example of Saccoglossus kowalevskii, a worm-like member of the hemichordates. It is found that the dorso-ventral axis in hemichordates is specified in a similar way to that in other animals but this axis is decoupled from the development of the central nervous system and implies that the rules governing dorso-ventral axis formation are ancient and probably evolved with the first bilaterally symmetrical (bilaterian) multicellular animals.

Something completely different
Article Abstract:
British Columbia's Middle Cambrian Burgess Shales yielded fossils of many arthropods and other invertebrate animals whose apparently strange body plans provoked controversy among paleontologists. Stephen Jay Gould and others argue that the strangeness is genuine, while Derek Briggs and others contend that the modern counterparts of the 540 million-year-old Burgess fauna are just as varied morphologically. The discovery of other Cambrian faunas in China, Greenland and South Australia affirmed the kinship between the Burgess metazoans and existing metazoans.
