Although it is the defining organ of the Chordata, the notochord and its cells are one of the least understood vertebrate organs. The presence of cartilage in the notochord raises questions about the evolutionary relationships between notochord cells and cartilage cells. This may be because large parts of the notochord are often replaced with cartilaginous or bony vertebral bodies.
For example, although the early signaling function of the notochord is conserved across the vertebrates, many will be surprised to find that the role of the notochord in vertebral body development in tetrapods is not the blueprint for all vertebrates. This book integrates classical analytical studies with recent palaeontological, experimental, and molecular studies in both developmental and evolutionary contexts. Recent studies on zebrafish and medaka embryos have uncovered the molecular mechanisms of a
