I kind of wonder whether certain cultural artifacts might be genetically inspired. My son, when he was young, without any prompting wanted to be an architect (like his great-grandfather whom he had never met, nor even heard anything about before this) and was obsessed with guitars (like me, although at that point, my own guitar had been in the basement for years and he had never seen me play it). This is not to say that these particular behaviors are explicitly encoded in genetics (both guitars and architecture as a discipline are much younger than evolutionary time), but rather that some intrinsic predisposition towards them exists (so, perhaps had we lived in fifteenth-century Persia, we would be oud-obsessed, to choose one posseible alternate reality).
