title: Animal phylogeny: root and branch surgery.
abstract: Our view of how-many phyla relate to each other is being radically revised by molecular phylogenetics. For example, arthropods and annelids are no longer placed together, but are now considered to be in separate clades. The new tree has important ramifications for developmental biology and genomics.
