Yes well I don't think Feynman's answer is the one single thing to be passed down myself, I am talking about its generalization in a conceptual, philosophical or mathematical sense. As for if this differs from Darwinian evolution perhaps, and perhaps they will both be subsumed under a comprehensive evo-devo-eco theory which is then generalized to a discipline agnostic model. Since they are two pieces of this triad it is difficult to choose between them.
