Evolutionary
Definition:
(a.) Relating to evolution; as, evolutionary discussions.
Example Sentences:
(1) Gradual evolutionary change by natural selection operates so slowly within established species that it cannot account for the major features of evolution.
(2) The paper develops a model as a framework for monitoring the course of the program through the policy cycle and recommends that the policy process be considered as dynamic, interactive, and evolutionary.

(6) For evolutionary biologists population variability per se has proven of interest.
