thanks!
I finally got through all of it. Gee whiz ... talk about chewing a cud.
But, it is digesting nicely now, and I can report that all the more do I understand the urgency behind last year's announcement from Harvard, that they were throwing millions into a independent new lab there to discover, eureka!, the origins of life. There was a thread about it I posted some time ago.
I found that one story to be very, very encouraging, and this commentary piece by D.Inst fellow is all the more compelling.
Thanks again.
