Evolutionary BiologyFutuyma (ecology and evolution, SUNY Stony Brook) covers such subject areas as phylogeny, paleobiology, genetic mechanisms of change and speciation, character evolution, the theory of processes and macroevolution, and new molecular perspectives. Numerous line drawings, charts, diagrams, and maps are provided. Annotation copyrighted by Book News, Inc., Portland, OR |

It is important to ask , though , whether true evolutionary novelties actually arise by mutation . For example , can both a new enzyme and the regulatory system that modulates its production arise by mutation ?
