An inventive mechanism (Evolution)

dhw: Once cells had merged to create multicellularity, there had to be cooperation between them, and clearly that means all the cell communities that constitute the whole organism must integrate their many mechanisms. Once again we are in agreement.-DAVID: Not completely. I won't let you go back to cells integrating on their own. They are controlled by the genome of the multicellular organism and it manages their integration. Yes, each cell has genes, tailored for that cell, but there has to be central control with a centrally controlling genome.-Of course there does. After initially refusing to countenance the idea that cells/cell communities might have the equivalent of a brain, you decided that they do have one after all and it is situated in the genome. The brain controls the cell/cell community, but it would be as impossible for cells/cell communities to integrate without their brains as for the brains to integrate without the rest of their cells. Would it really make sense to say that genomes merged to create multigenomity and genome communities constitute the whole organism and must integrate their many mechanisms? Please can we move on. (See also under “...another outside discussion”.) -May I once again ask if you now accept that “inventive” means “creating new things and performing new actions without being preprogrammed”?
