Fuzzy/raw idea about a response to those who find an adaptive basis for distinctively human modes of cognition: what is the adaptive basis for non-Euclidean geometry? Evolution does not allow for us to be over-engineered, but we are overengineered in the sense that a thousand years ago, we were genotypically ready to do forms of math invented only in the last two centuries and to listen to/compose symphonies.
How about defining it as an instance of functional complexity? And treating the list of properties as following necessarily from this definition? Okay, this is very diamond-in-the-rough (or perhaps zirconium...) but here goes my thoughts on the matter: (Complexity) Many diverse parts (functional) acting for the sake of the whole I think I need to add something like "not as the instrument of another" or something like that. Given that they act together as one whole and given entropy, etc., the organism will need to posses more order than its surroundings (homeostasis). It will therefore need to take in energy (nutrition), which it will use to sustain its readiness to interact with its environment so as to preserve its own being (homeostasis again?), but which will eventually break down (death), so that in order for that life form to continue it will need to duplicate itself (reproduction), which, upon occurring, will involve both development (growth) to maturity and...
