 Given the number of different types of evolutionary dynamics, as seen in section 2.2, and the number of different concepts of evolutionary stability, as seen in section 2.1, a first question to ask is what relationships exist between the two?

Answers to these questions turn out to be more subtle and complex than one might first anticipate.
