Summary

A novel account of the evolution of language and the cognitive capacities on which language depends.

In From Signal to Symbol, Ronald Planer and Kim Sterelny propose a novel theory of language: that modern language is the product of a long series of increasingly rich protolanguages evolving over the last two million years. Arguing that language and cognition coevolved, they give a central role to archaeological evidence and attempt to infer cognitive capacities on the basis of that evidence, which they link in turn to communicative capacities.

Countering other accounts, which move directly from archaeological traces to language, Planer and Sterelny show that rudimentary forms of many of the elements on which language depends can be found in the great apes and were part of the equipment of the earliest species in our lineage. After outlining the constraints a theory of the evolution of language should satisfy and filling in the details of their model, they take up the evolution of words, composite utterances, and hierarchical structure. They consider the transition from a predominantly gestural to a predominantly vocal form of language and discuss the economic and social factors that led to language. Finally, they evaluate their theory in terms of the constraints previously laid out.

  • “Scholarly and accessible, From Signal to Symbol gives us language without miracles—a subtle, gradualist account of the evolution of language richly informed by scientific evidence. Come for the philosophical clarity and stay for the 'firelight niche'.”

  • “In this rich and valuable book, Planer and Sterelny defend a plausible account of the evolution of human communication embedded in a deeply informed, interdisciplinary account of hominin ethology. The book is full of both fascinating ideas and provocative challenges to existing views. It will reward careful study.”

    Richard Moore

    Professor of Philosophy, University of Warwick

  • “Once banned by the Linguistic Society of Paris, research on language origins is now a diverse and vibrant field of study. Planer and Sterelny provide an innovative and authoritative synthesis of this expansive literature, ranging from Formal Language Theory to the evolutionary importance of fireside chats. Eschewing miraculous 'single cause' explanations, they develop a meticulous and incremental account of the complex origins of human language that is sure to stimulate further research and provide a key reference for anyone interested in this rapidly developing field.”
