Q.E.D. Where is the evidence of the energy? Does the needed higher temperature remain low enough to allow a double helix, or does the required temperature result in the molton world shown in your pictures? The "random" in random selection is defined as haphazard or without definite method or purpose. Spontaneous is defined as acting without compulsion, constraint or premeditation. I stand by my statement.

Wow! I didn't know anyone was still following this thread...

That's not really how natural selection works - initial changes & mutations are random, but the mechanism of natural selection forces the propagation of only traits that are favorable to continued reproduction - this is a very definite method/purpose and not haphazard at all.

Of course there are still many open questions about the thermal conditions necessary for the chemical evolution of life (particularly earliest life), but just because we can't identify all these parameters, doesn't mean we don't have other evidence in support of evolution. (I don't know the temperature & thermodynamic conditions on the night OJ killed Nicole, I infer that it happened from other circumstances.)

My point is that thermodynamics does not prove evolution impossible (or even unlikely, for that matter - order from disorder in thermodynamic subsystems is oberved all the time). We just simply don't know (and for the moment, can't know) the thermal boundary conditions specific to isolated biological systems millions or billions of years ago and have to search along other lines of inquiry for evidence. Thermodynamics just doesn't help much, either in a positive or negative way here.
