Fish, or lower vertebrates, occupy the basal nodes of the vertebrate phylogeny, and are therefore crucial in interpreting almost every feature of more advanced vertebrates, including amphibians, reptiles, birds and mammals. Recent research focuses on combining evolutionary observations - primarily from the fish fossil record - with developmental data from

Although at first glance mechanisms used to create the variable domains of immunoglobulin appear to be designed to generate diversity at random, closer inspection reveals striking evolutionary constraints on the sequence and structure of these antigen receptors, suggesting that natural selection is operating to create a repertoire that anticipates or

The marriage of evolutionary biology with developmental biology has resulted in the formation of a new field, evolutionary developmental biology, or “evo-devo. This volume reviews current research findings and thought in the broad field of evo-devo, looking at the developmental genetic mechanisms that cause variation and how alterations of these
