Dawkins was in SF, 10-06
- lecture, audience Q&A re. book. (Replayed on NPR recently)
He described the speed at which some Petri-dish denizens spontaneously reprogram their DNA.. as in, Now! Kid! when their fav food is in short supply. (No Executive permission sign-off appears a necessary stage of the 'Change Now or Die Soon' process.)
Clearly critters operate quite faster than the MBA/Econ brain in-search-of a next monopoly. But Western medicine is so inextricably entwined within the Growth-fetish of vulture capitalism (and the treating of symptoms, as opposed to restoring overall health) - I've no idea how many generations would be necessary to reprogram such an incestuous behemoth / even if a lot of people noticed why you must.
('Course too, in the more complex organisms - as can program an i-Pod, say - noticing.. that you Are running out of food/energy/smarts? - takes much more time than Petri Warz. Assuming you have that. Time, that is.)
Oh well..
