The evolution of new phenotypes and species is a population genetic process that is governed by four fundamental forces: natural selection, drift, mutation, and gene flow. Ecological genetics is the reciprocal interaction between population genetic theory and empirical observations from nature and the laboratory. Here I present ...
Enhancing Evolution: When Spatial Structure and Environmental Change Improve Adaptation
Evolution by natural selection is the primary creative force in biology. In order for populations to thrive, or even survive, requires a continual generative process. An understand of the process of natural selection, its strengths and weaknesses, is necessary for both predictions about the future course of life, as well as ...
