Deuterostome Monophyly and Phylogeny

  • Bobb Schaeffer


The abundant data of developmental biology, both descriptive and experimental, are scattered through many serial publications and symposium volumes. However, the diversity that has been investigated by classical and modern techniques is relatively small. This is related to the reductionist aspect of much developmental research, to a minimal interest in a comparative approach, and to the availability and suitability of laboratory animals. Most symposium reports that I have examined offer little actual synthesis, although they cover key topics such as differential gene action, embryonic induction, and pattern formation.
