> dhw: No-one claims that individual molecules have a brain! As you know perfectly well, the argument is that cells/cell communities have a brain equivalent which coordinates all the molecular activity. As for your final sentence, Shapiro says: “Large organisms chauvinism, we like to think that only we can do things in a cognitive way.” (See also “Quorum sensing”)-Same old problem: either the one celled act intelligently because they have a degree of it ,or they act intelligently because they are following implicit instructions. No one can tell which.

> dhw: We have always agreed on this. An autonomous inventive mechanism would explain the change. Some single cells remained single while others merged to launch multicellularity.-I have agreed but we still don't know why multicellularity happened by what process or for what reason. It is a difficult step for evolution, and offers a reason to consider design or guidance. - 
> dhw: You have reversed my concept! My single cell guys did NOT know everything from the beginning. That is the whole point. They cooperated, and as the environment changed, so they adapted or innovated (or died). Hence the higgledy-piggledy extinctions, weird forms and lifestyles of evolution. -It is a nice thesis. Finds a nice third way around God or UI guidance. Something makes all of life very inventive. I have my choice. you have yours.
