Summary

  • Animal phylogeny is undergoing a major revolution due to the availability of an ever increasing amount of molecular data, the application of novel methods of phylogenetic reconstruction, and advances in palaeontology and molecular developmental biology.This book revises the major events in animal evolution in the light of these recent advances. - ;Animal phylogeny is undergoing a major revolution due to the availability of an exponentially increasing amount of molecular data and the application of novel methods of phylogenetic reconstruction, as well as the many spectacular advances in palaeon
