“Using a brilliant collection of data from different fields, this book provides novel insights into the emergence and evolution of language. It is a solid contribution to the literature and a must read for anyone interested in language evolution. … this book by Progovac is a worthwhile addition to the body of knowledge, one that I enjoyed reading and one that stimulated my thinking about language evolution in new and hopefully productive ways.” (Majid Manoochehri, Evolutionary Psychological Science, Vol. 7, 2021)
