I should check out this article at Trueorigins.org.

The key paragraph to me is, after having described how a "program" (DNA) and "energy conversion mechanisms" (chlorophyll) mean that living organisms are compatible with the second law of thermodynamics:

While this explains how living organisms may grow and thrive, thanks in part to the earth’s “open-system” biosphere, it does not offer any solution to the question of how life could spontaneously begin this process in the absence of the program directions and energy conversion mechanisms described above— nor how a simple living organism might produce the additional new program directions and alternative energy conversion mechanisms required in order for biological evolution to occur, producing the vast spectrum of biological variety and complexity observed by man.

Eh? We've established that the possibility of living organisms who grow and reproduce is not forbidden by the laws of thermodynamics. That's all thermodynamics have to say about it. Where those organisms came from, and whether/how they change across generations is a completely separate, orthogonal issue, and most of the paper from "Steiger's Brand of Thermodynamics" onwards is irrelevent for the question of whether evolution is possible.

That's an interesting point. Keep in mind, first of all, that I haven't read that page yet. But like I said last time, even if the 2nd law of thermodynamics isn't violated by evolution, an input of energy isn't sufficient to create an increase in complexity or to transform non-living chemicals into living creatures. Evolution still has no viable mechanism.

We've established that the possibility of living organisms who grow and reproduce is not forbidden by the laws of thermodynamics.

Yes, but like I said last time as well, that's only because there is a machine or an ordered process that serves to keep the process going, repair damage, etc. Ultimately though, the second law kills us as our cells break down and our body isn't able to repair itself any longer.
