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 |

Because this milieu varies , the phenotypic expression of a gene also varies .
This milieu can be altered by variation in the genetic environment or sometimes
in precisely the same ways by variation in the external environment : temperature
