More on abiogenesis, via RD.net:-http://nirmukta.com/2009/11/13/complexity-explained-9-how-did-complex-molecules-like-proteins-and-dna-emerge-spontaneously/-There may not be much new here, but it expresses the process clearly.-Quote: Thus: A facilitates the production of B, and B does the same job for C, and so on. Given enough time, and a large enough pool containing all sorts of molecules, it is quite probable that, at some stage a molecule, say Z, will get formed (aided by catalytic reactions of various types), which would be a catalyst for the formation of the catalyst molecule A we started with.-Once such a loop closes on itself, it would head towards what we now call self-organized criticality (and order). There will be more production of A, which will lead to more production of B, and so on. The plausibility advantage of this scenario visualised by Stuart Kauffman is that there is no need to wait for random reactions for the spontaneous formation of large molecules. And once a threshold has been crossed, the system is likely to inch towards the edge of chaos, and acquire robustness against destabilizing agencies.
