Dhw: If cells were programmed, they would not have to exchange information or “talk” to nearby cells or “compare notes” or, above all, make decisions. The decisions would already have been made for them. -I know you still insist that cells are automatons. My point is that these researchers disagree with you, so please explain how the above MEANS that cells are programmed and therefore do not take their own decisions.-DAVID: It is still the same battle. These cells communicate with molecular reactions as their 'talk'. The responses can be automated decisions as I've told you over and over.-I'm afraid this is another case of failed communication between us. I was only repeating what the researchers said and asking why you think their findings support your opinion.-dhw: Unless you can explain how processing and exchanging information before making a decision constitutes preprogramming, I would suggest they are on the side of the “intelligent cell” brigade.-DAVID: Very simple: cell A sends a series of molecules B,C,D. Cell E receives them and this sets off an automatic response of molecules F,G, and H back to A. We were taught several series of these reactions in biochemistry in Med school. This is how cells 'talk'.-Once again, I know you believe what you were taught at medical school. I am only pointing out that these researchers do not say cellular communication is automatic, but on the contrary emphasize the active, individual link between information processing, communication, cooperation and, above all, decision-making, which are hallmarks of intelligence. I am not asking you to change your belief. I am simply asking you to accept that these researchers disagree with you.
