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 |

Clearly evolution cannot exist without preexisting variation . Evolution can consist
of changes at each of the levels at which variation exists . So the evolution of
body size can be described as changes in the proportions of large vs. small ...

As long as additive genetic variance exists for a character like viability , the mean
viability will continue to evolve ... But why , given the conclusion that the
population should become monomorphic for such a trait , does the variation exist
?
