Human language is unique among animals. We assume that complex cognitive capacities in general and language in particular evolved gradually and thus are manifest in different kinds and/or degrees in other animals demonstrating social communication. This assumption is supported by the fact that we can train social species from very different groups of animals (e.g. great apes, dolphins, dogs, parrots) to understand and in several cases even use abstract symbols for communication with humans and conspecifics. Even simple grammatical rules for sequences of 2-3 symbols can be trained to be understood by several species (e.g. great apes, dogs, dolphins). Even though human language training in these species takes considerable time and effort, it convinces us that cognitive foundations for language are present in other species, and, given the relevant selection pressures, symbolic communication could evolve in other species.

Communication is a basic behaviour, found across animal species. Human language is often thought of as a unique system, which separates humans from other animals. This textbook serves as a guide to different types of communication, and suggests that each is unique in its own way: human verbal and nonverbal communication, communication in nonhuman primates, in dogs and in birds. Research questions and findings from different perspectives are summarized and integrated to show students similarities and differences in the rich diversity of communicative behaviours. A core topic is how young individuals proceed from not being able to communicate to reaching a state of competent communicators, and the role of adults in this developmental process. Evolutionary aspects are also taken into consideration, and ideas about the evolution of human language are examined. The cross-disciplinary nature of the book makes it useful for courses in linguistics, biology, sociology and psychology, but it is also valuable reading for anyone interested in understanding communicative behaviour.

Despite its inherent interdisciplinarity, the Communication discipline has remained an almost entirely anthropocentric enterprise. This book represents early and prominent forays into the subject of human-animal communication from a Communication Studies perspective, an effort that brings a discipline too long defined by that fallacy of division, human or nonhuman, into conversation with animal studies, biosemiotics, and environmental communication, as well as other recent intellectual and activist movements for reconceptualizing relationships and interactions in the biosphere. This book is a much-needed point of entry for future scholarship on animal-human communication, as well as the whole range of communication possibilities among the more-than-human world. It offers a groundbreaking transformation of higher education by charting new directions for communication research, policy formation, and personal and professional practices involving animals.

The Author of this new volume on ant communication demonstrates that information theory is a valuable tool for studying the natural communication of animals. To do so, she pursues a fundamentally new approach to studying animal communication and “linguistic” capacities on the basis of measuring the rate of information transmission and the complexity of transmitted messages. Animals’ communication systems and cognitive abilities have long-since been a topic of particular interest to biologists, psychologists, linguists, and many others, including researchers in the fields of robotics and artificial intelligence. The main difficulties in the analysis of animal language have to date been predominantly methodological in nature. Addressing this perennial problem, the elaborated experimental paradigm presented here has been applied to ants, and can be extended to other social species of animals that have the need to memorize and relay complex “messages”. Accordingly, the method opens exciting new dimensions in the study of natural communications in the wild.
