You can count on Julian to have something stimulating to say at the drop af a hat or a challenge. Yes, no doubt there are galaxies of small molecules in and around bacteria in communities and a lot of them must say and do something. However, there must also be a functional selection mechanism just as the overall genomic regulation has to make provision for functional sequencing and selection of required mechanisms and functions. It is clear that nature has the useful capability of seeing that genes or parts of genes that might be useful sometime are retained for future use while being either in repose or achieving some other function. I read today that the outermost cells on a sponge have functional genes that have a function in generating nerve cells in the metazoans. So one can argue for a form of conservation that all living things can mannage to their future advantage - to kill or to cure!
