“While the archaeological evidence remains contested, that from neuroscience and genetics provides a compelling case for linguistic and cognitive differences between H. neanderthalensis and H. sapiens.”
“The Neanderthals had a relatively large occipital lobe, devoting more brain matter to visual processing and making less available for other tasks such as language.
They also had a relatively small and differently shaped cerebellum. This sub-cortical structure, which is packed with neurons, contributes to many tasks including language processing, speaking and fluency. The uniquely spherical shape of the modern human brain evolved after the first Homo sapiens had appeared at 300,000 years ago.”
Mithen is the guy of ‘singing neanderthals’ fame and hmm (holistic, multimodal, mediated) communication (I believe there is a copy in the party library).
I suspect that the article is related to that he has a new book out:
