omplex nervous system patterning—usually assumed to have coevolved with advanced, centralized nervous systems— may have arisen before nerves consolidated into a central nerve chord, according to Christopher Lowe, John Gerhart (University of California, Berkeley, CA), Marc Kirschner (Harvard Medical School, Boston, MA), and colleagues. Their idea runs counter to the prevailing theory of dorsoven...

Recent evidence, however, suggests that the intestinal epithelium might play a major role in the development and perpetu...
