Sociobiology of Communication: An Interdisciplinary Perspective explores the evolution and biological foundations of communication across a wide variety of living organisms. Bringing together contributions from leading researchers, the book examines how communication systems have evolved and function in bacteria, insects, birds, mammals, and humans. It integrates findings from evolutionary biology, behavioural ecology, microbiology, genetics, neuroscience, linguistics, and psychology to identify common principles governing communication. The volume discusses topics such as bacterial signalling, chemical communication in insects, social interactions among vertebrates, communication between hosts and parasites, neurobiology of olfactory communication, sexual signalling, genomic conflict, cooperation, language evolution, and information transfer. Each chapter highlights current research while demonstrating how communication shapes social organization, adaptation, and evolutionary success across species. Intended primarily for graduate students, researchers, and professionals in evolutionary biology and behavioural sciences, the book provides a comprehensive synthesis of modern theories and empirical studies on biological communication. It also offers valuable insights for scholars in psychology, anthropology, linguistics, and related disciplines interested in the evolution of social behaviour.
