Written by the leading experts in the field, this book examines the evolutionary advantages of gender dimorphism and sexual dimorphism in flowering plants. Divided into three sections: the first introduces readers to the tremendous variety of breeding systems and their evolution in plants and sets the stage for a consideration of the evolution of dimorphism in reproductive and non-reproductive characters. The second section deals with the evolution of secondary sexual characters, including the theory related to the evolution of sexual dimorphism and its empirical patterns, while the last section deals with the genetics of gender expression and of secondary sexual characters.

Are humans unwitting partners in evolution with psychedelic plants? Darwin’s Pharmacy shows they are by weaving the evolutionary theory of sexual selection and the study of rhetoric together with the science and literature of psychedelic drugs. Long suppressed as components of the human tool kit, psychedelic plants can be usefully modeled as “eloquence adjuncts” that intensify a crucial component of sexual selection in humans: discourse. Psychedelic plants seduce us to interact with them, building an ongoing interdependence: rhetoric as evolutionary mechanism. In doing so, they engage our awareness of the noosphere, or thinking stratum of the earth. The realization that the human organism is part of an interconnected ecosystem is an apprehension of immanence that could ultimately benefit the planet and its inhabitants. To explore the rhetoric of the psychedelic experience and its significance to evolution, Doyle takes his readers on an epic journey through the writings of William Burroughs and Kary Mullis, the work of ethnobotanists and anthropologists, and anonymous trip reports. The results offer surprising insights into evolutionary theory, the war on drugs, the internet, and the nature of human consciousness itself.
