I happen to believe that the answers, if we ever get any here in this life, will come from physicists and not geneticists. All the biologists can demonstrate absolutely is a kind of progressive interrelatedness of life. Then they draw all kinds of unjustified conclusions from that interrelatedness. The trouble with biologists is that they can't be satisfied with the useful thing they've accomplished, and want to play priest. But once you start thinking about time and Who masters it--none of the other stuff matters.

You have good points. Yes, who masters it matters. The "how" of the process is something that nobody can explain fully.
