Hormones, Reproductive Behavior, and Speciation

A research plan is outlined which combines two ordinarily separatelines of investigation, namely, the reciprocal interaction betweenhormones and behavior and the role of behavior in the evolutionand maintenance of species, bringing both to bear on outstandingquestions in behavioral and evolutionary biology. This integrativeapproach to animal behavior, which spans three levelsµphysiology,behavior, and evolutionµshould not only yield answersto specific questions within each level of analysis, but, bytaking into account the adaptive value of each in nature, alsodemonstrate interrelationships between the leve.
