Biological complexity: feedback loops are vital (Introduction)

dhw: [...] information is not active (and not intelligent and not functioning), and it requires the intelligence of organisms to use it. Perfectly simple.

DAVID: In regard as to how organisms operate, let me ask a question. Have you ever followed instructions from a pamphlet or book to create something or respond to something? That is how I view organisms and information. You used the information actively and created.

dhw: Precisely. I am an intelligent organism (I hope you’ll agree), and I actively use my intelligence to create something out of whatever non-intelligent, non-functioning instructions/information are at my disposal. Thank you for an excellent analogy.[…]

DAVID: The organisms work just as you do in the analogy. You are free to act. They are automatic with programmed responses to the instructional information.

If organisms work just as I do, and I am free to act, how do you manage to conclude that organisms are not free to act but are automatic and your God preprogrammed them 3.8 billion years ago?!

DAVID: (re ant colonies) As with bridges, automatic individual reactions make the whole colony operate as a unit.

dhw: They take new decisions every day according to individual reactions, but clearly they retain memory of earlier successful discoveries (e.g. how to form a bridge). Where have you found the word “automatic”? Do you really believe your God dabbles each new decision, or preprogrammed it 3.8 billion years ago? […]

DAVID: You should go back to ant bridge studies: individual ants do what they are programmed to individually do in that circumstance as all other situations. The overall colony acts through these individual actions, as the Article shows.

Once again: the bridge would have been the result of individuals pooling their intelligence to find a solution to a problem. Once the solution had proved successful, it would have been passed on, and so of course subsequent generations would follow the same procedure. It is when new conditions arise that individuals pool their intelligence to find new solutions. This is what “the article shows”: “from day to day the colony’s behaviour changes” and they “decide what to do next”… Not “3.8 billion years ago God supplied the first cells with a programme to pass on for whatever ants do next, on a day to day basis.”
