> DAVID: The limits are restrictions on the direction and extent of innovations. > > dhw: Thank you for repeating part of my own argument. I take this as your acknowledgement that there are no guidelines as to how to invent the innovation, and so either the invention is 100% God's or 100% the organism's.-We are at the level of guesswork. From our knowledge of epigenetics, I believe an organism can initiate change, but how much and how far is restricted, as noted above. I think we might agree.
