Generalist Species Species that can survive and tolerate a broad range of environmental conditions. Genetic Adaptation Changes in the genetic makeup of organisms of a species due to mutations that allow the species to reproduce and gain a competitive advantage under changed environmental conditions. Genetic Diversity Genetic variability found in a population of a species or all of the populations of a species.
