The evolution of the vertebrates--genes and development.
In the past year, studies on protochordates have provided evidence that many features that we take to be indicative of the vertebrates were evident early in chordate evolution. Furthermore, many of the important developmental regulatory genes have also been identified in these invertebrates. Finally, we are also gaining a better insight into how the vertebrate genome itself evolved.
