Good post Bette.
Here is something else of interest on the science front. http://www.wired.com/wiredscience/2012/ ... llularity/
This research shows that no special conditions are necessary to create multicellular entities. Simply environmental pressure in that direction has produced multicellular yeast in 60 days with true specialization of cell function and an organism that reproduces as multicellular and that 'grows up' and will not reproduce until it is mature.
It is suggested, and sounds like, the method will have advantages easily applied to production of ethanol or other such production using single celled organisms as presently employed.
