> I agree that communication is accomplished by molecular reactions if by that you mean chemical processes. And although you have changed the terminology from decision-making to algorithms (so much more scientific than your usual God's instructions), you have agreed that we don't know what it is that dictates the “chemical cascades”, i.e. how cells decide to react in a certain manner. "Fully understand” is one of those weasel expressions to suggest that we are almost there.-Sorry, either I'm not clear or you are twisting words. By 'fully understand' I did mean we are still learning how all these chemical reactions work in algorithms. They are being elucidated. Cell gets stimulus, cell responds with automatic chemical reactions, response may well be controlled by feedback loop of molecules. The Krebs cycle, which I have shown before is a typical loop which is stimulated. It is all chemicals, all automatic.-> dhw: Our biggest problem is how cell communities innovate, i.e. decide to form new communities, but it may all be accomplished by the same mechanism. Your God's "instructions"? My cellular intelligence? -Ah, still on the fence.
