Chapter 20, Problem 4DA
Summary Introduction
To determine: Theapplication of the experiment to distinguish between frequency dependent and directional selection.
Introduction: Selection pressure does lead to evolution, but it is not the requirement for evolution to occur. The members that fit to survive in the changing condition will evolve into a more efficient and improved species.
