The universality of generative brain mechanisms underlying music, maths and language, and perhaps other abilities, may respond to common neurophysiological mechanisms. This is inspiring and may provide with an interesting framework to get closer to the biology of those human capacities. In a way, generativity and recursion may be embedded in life as one aspect of adaptation, as the obstinate fate of organisms to replicate and change at the same time: rules for repetition and variation that are driving forces for evolution, powerful self-perpetuating mechanisms. After all, what are DNA and evolution if not an example of recursion?
