"Deutsch and her colleagues, in their 2006 paper, suggested that their work not only has "implications for the issues of modularity in the processing of speech and music...[but] of the evolutionary origin" of both. In particular, they see absolute pitch, whatever its subsequent vicissitudes, as having been crucial to the origins of both speech and music. In his book The Singing Neanderthals: The Origins of Music, Language, Mind and Body, Steven Mithen takes this idea further, suggesting that music and language have a common origin, and that a sort of combined protomusic-cum-protolanguage was characteristic of the Neanderthal mind."
