"What if we’re not, in fact, meant to have language and music? (...) The reason we have such a head for language and music is not that we evolved for them, but, rather, that language and music evolved—culturally evolved over millennia—for us. Our brains aren’t shaped for these pinnacles of humankind. (...)
These pinnacles of humankind are shaped to be good for our brains. (...) They’d have to possess the auditory structure of…nature. That is, we have auditory systems which have evolved to be brilliantly capable at processing the sounds from nature, and language and music would need to mimic those sorts of sounds in order to harness—to “nature-harness,” as I call it—our brain. (...)
Human speech sounds like solid objects events, and music sounds like human behavior. (...) Being human today is quite a different thing than being the original Homo sapiens. (...) Unlike Homo sapiens, we’re grown in a radically different petri dish. Our habitat is filled with cultural artifacts—the two heavyweights being language and music—designed to harness our brains’ ancient capabilities and transform them into new ones.
Humans are more than Homo sapiens. Humans are Homo sapiens who have been nature-harnessed into an altogether novel creature, one designed in part via natural selection, but also in part via cultural evolution.”
