It is unlikely that any other species, including our close genetic cousins the Neanderthals, ever had language, and so-called sign ‘language’ in Great Apes is nothing like human language.

A case can be made that language has played a more important role in our species’ recent (circa last 200,000 years) evolution than have our genes.
