This volume examines pheromones, the chemical signals that animals release to communicate with other members of their species. These substances orchestrate a wide variety of activities; they can attract mates, warn of danger, mark territories, lead to sources of food. The book ably conveys the variety and importance of pheromones from single-celled organisms to human beings. It demonstrates the universality of certain pheromonal structures, which occur repeatedly, offering clues to the evolutionary connection among organisms. "Chemical Communication" approaches its subject from the viewpoint of the chemist who isolates and identifies the pheromonal molecule. It gives insight into the practical work of the organic chemist and illustrates the abundant contributions of chemistry to the study of biology. The author also describes what physiologists have learned about how the pheromone's message is received and translated.
