So what does evolution prescribe then?
Ok, this is a first attempt: does Evolution prescribe "limiting rehashing past successes, in favour greater newer succession"?
Or wait, is that random? I can never tell when you mean what you say, it always seems to be about how wonderfully benign biology is?
Scripturally, Jesus prescribes not swearing by the hair on your head, because it can't be made white or black - that is definitely a prescription.
If Jesus says "don't swear" once, He means it for all time; so I guess Evolution would prescribe to "swear less" (that is even by those things that would be more effective, if swearing worked)?
You can see that prescribing swearing less, would ultimately save Evolution, from pressure to ignore what can't be adapted, at all?
Let me know if I have lost you, I'm trying to pick the most dependable prescription I can find - to help you get the surest adaptation, on the basis of what you "say" is 'necessary change'?
You wouldn't insist something be adapted, if you knew it could never be done, right?
