Some plant species are not able to acclimate when transferred from a sunny to a shady environment, or vice versa, lack of acclimation indicates that these plants are specialized for either a sunny or a shady environment. When plants adapted to deep-shade conditions are transferred into full sunlight may leaves experiences;

The lakes of northern Minnesota are home to many similar species of damselflies of the genus Enallagma that have apparently undergone speciation from ancestral stock since the last glacial retreat about 10,000 years ago. Sequencing which of the following would probably be most useful in sorting out evolutionary relationships among these closely related species?
