“A culture can be thought of as ever-evolving software that sits on top of—and synergistically interacts with—both biological hardware and firmware, addressing flaws our biology hasn’t had sufficient evolutionary time to address. To go further with this analogy: Biological evolution provides some basic coding, much like a low-level programming language might for a given hardware, whereas cultural evolution manipulates the high-level, object-oriented code that lets us program highly nuanced behaviors.”
