This is a unique view of the origins of language, describing what linguistic science would look like if sign language rather than speech was used as the basis for the study of language systems.

"Ruhlen is a leader in the new attempt to unify the theory of language development and diffusion."––Library Journal "A powerful statement...also a wonderfully clear exposition of linguistic thinking about prehistory."––Anthropological Science One of the world's foremost language researchers takes readers step-by-step through the hotly contested evidence that all modern languages derive from one "mother tongue" once spoken by primitive humans in Africa. With The Origin of Language, Merritt Ruhlen makes this fascinating science accessible to readers with no linguistic background. MERRITT RUHLEN, PhD (Palo Alto, California) is the author of A Guide to the World's Languages

This book offers an accessible overview of what is known about the evolution of the human capacity for language and what sets human language apart from the simple communication systems used by non-human animals. It draws on a wide range of disciplines, including philosophy, neuroscience, genetics, and animal behaviour.

How human language evolved from the need for social communication The origins of human language remain hotly debated. Despite growing appreciation of cognitive and neural continuity between humans and other animals, an evolutionary account of human language—in its modern form—remains as elusive as ever. The Social Origins of Language provides a novel perspective on this question and charts a new path toward its resolution. In the lead essay, Robert Seyfarth and Dorothy Cheney draw on their decades-long pioneering research on monkeys and baboons in the wild to show how primates use vocalizations to modulate social dynamics. They argue that key elements of human language emerged from the need to decipher and encode complex social interactions. In other words, social communication is the biological foundation upon which evolution built more complex language. Seyfarth and Cheney’s argument serves as a jumping-off point for responses by John McWhorter, Ljiljana Progovac, Jennifer E. Arnold, Benjamin Wilson, Christopher I. Petkov and Peter Godfrey-Smith, each of whom draw on their respective expertise in linguistics, neuroscience, philosophy, and psychology. Michael Platt provides an introduction, Seyfarth and Cheney a concluding essay. Ultimately, The Social Origins of Language offers thought-provoking viewpoints on how human language evolved.

First Published in 1959 The history and origin of language deals with one of the most important and most fascinating subject matter of all human historical problems-that of the origin and development of language. It is the first attempt to solve it, not by a priori methods, but by marshalling and analyzing the whole of the evidence. It is a work of great originality by a scholar who has written other well-known sociological works, and the treatment is that of the sociologist. Dr Diamond writes for the intelligent layman as well as the linguist. He first seeks the true nature of language and its true function and structure in modern society and traces the paths along which language has developed and changed in its known history, both in the forms of its words and in their meanings, examining for this purpose many languages of civilized and primitive peoples. These paths he then pursues backwards with the aid of data from human physiology, the language of children, and observations of animal behaviour, and shows how all these paths converge to one beginning and deduces how language originated-both the form of its first words and their meanings. He finally shows relics of these earliest words and meanings in languages which still survive. The arguments are cumulative and many sided, and the case made is convincing. This is a must read for scholars and researchers of linguistics.
