Right, people study it and write lots of papers about it. None of that activity implies we understand the origins of life. If we really got it, someone could set up a chemical soup out of which an organism arose. No one's done that. It really does boil down to demonstration: if we really understood it we could make it. There'd be no "creation science" or "irreducible complexity" mumbo jumbo if we really had answers. Craig Venter's venture to create a "minimal" organism is the most ambitious I know of to date. But still, that organism would be built out of a minimum complement of DNA taken from existing organisms, using machinery also taken from existing organisms. Should this venture work, it would still not explain how all the necessary ingredients arose out of the primordial soup and then, most critically, ORGANIZED IN JUST THE RIGHT WAY. Because it's not a matter of the right parts arising in the soup, it's a matter of the very special way those parts are put together and interoperate. The latter is orders of magnitude harder to understand and explain. Perhaps you'd object less if I put it: compared to what we know about examples of life and life processes, we know next to nothing about how life itself arose. When I said "our modern science does not study those questions, really" here's what I mean. The "really" is the keyword. Of course people study those questions. But in my estimation, to *really* study the questions, one has to do a lot of hard, basic research. "Artificial Life" has existed since the 1850's (yes, I do mean *eighteen* fifties), yet has never borne fruit, and not for lack of trying. Clearly this is a hard problem on which existing approaches have not succeeded. Do we have some kind of magic now that will let us make some incremental leap from what we already know and land us in a place where we finally get it? I'll gamble on "no" as an answer to that. I think we need a fundamentally new idea to crack the nut of artificial life (and by extension origins of life). To get that idea requires an honest, fresh look at the problem and not a simple regurgitation of existing ideas and techniques. So who, among the authors you cited, is getting right down to basics, to the brass tacks of life, and studying the problem anew from a novel angle? Can you tell me to help me focus my reading? Because if I had to bet on it, I'd put my money on "no one." Anthony
