Origins of spoken language pushed back to 500,000 years ago

Could spoken language – instead of originating with AMH some 50,000 -100,000 years ago – have originated with the common ancestors of AMH, Neandertals and Denisovans perhaps 500,000 years ago?

A new paper suggests it could have:

Dan Dediu and Stephen C. Levinson, Front. Psychol., 05 July 2013, On the antiquity of language: the reinterpretation of Neandertal linguistic capacities and its consequences, doi: 10.3389/fpsyg.2013.00397

It is usually assumed that modern language is a recent phenomenon, coinciding with the emergence of modern humans themselves. Many assume as well that this is the result of a single, sudden mutation giving rise to the full “modern package.” However, we argue here that recognizably modern language is likely an ancient feature of our genus pre-dating at least the common ancestor of modern humans and Neandertals about half a million years ago. To this end, we adduce a broad range of evidence from linguistics, genetics, paleontology, and archaeology clearly suggesting that Neandertals shared with us something like modern speech and language. This reassessment of the antiquity of modern language, from the usually quoted 50,000–100,000 years to half a million years, has profound consequences for our understanding of our own evolution in general and especially for the sciences of speech and language. As such, it argues against a saltationist scenario for the evolution of language, and toward a gradual process of culture-gene co-evolution extending to the present day. Another consequence is that the present-day linguistic diversity might better reflect the properties of the design space for language and not just the vagaries of history, and could also contain traces of the languages spoken by other human forms such as the Neandertals.




The antiquity of modern language and speech capacities,
going back to at least the last common ancestor of Neandertals, Denisovans and modern humans some half a million years ago, raises new and interesting questions concerning the nature of the linguistic design space, the relationship between biological and cultural evolution, and the time frame for the emergence of modern human traits, and language in particular.
