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.

"Focused around a central essay by Seyfarth and Cheney, with five commentary essays by experts from relevant fields, this book is original in its specific linking of key generative features of language with the brain mechanisms and social functions of nonhuman primate communication. It will be read widely within primatology and language evolution circles."--Thom Scott-Phillips, author of Speaking Our Minds
