Iconic origins of language? An essay review of Steven Mithen’s The Language Puzzle (2024)

This essay review explores Steven Mithen’s interdisciplinary approach to the origins and evolution of language in The Language Puzzle (2024). It focuses mainly on what I call his iconic vocal origins hypothesis. Mithen challenges the prevalent gestural origins hypothesis, suggesting instead that early prehistoric languages were predominantly vocal and iconic, with conventionalization – as characteristic of symbol use – emerging later. The Language Puzzle draws on research from archaeology, philosophy, computer science, developmental psychology, and many other fields, thus assembling a wealth of insights from various disciplines. While intriguing, Mithen’s suggestion that prehistoric languages may have relied on iconicity instead of conventionalization faces substantial problems, which are discussed in this review essay. In the final section, I also briefly review the important conclusion chapter of Mithen’s book, which contains an imaginative outline of how language evolved from the last common ancestor up until modern H. sapiens. My criticisms of the iconic vocal origins hypothesis notwithstanding, The Language Puzzle is a valuable resource for anyone interested in language evolution, and once again showcases Mithen’s wide-ranging expertise and masterful writing.
