I posted to same newsgroups that adman and others did when claiming that thermodynamics proved (they believed) evolution to be unscientific. I do not follow most of those newsgroups and do not know people. However i have tried to maintain the explanation the more simple possible (but still in scientific terms). I reject the idea that a rise in entropy would be in conflict with complexity based on a much simpler idea: A star converts less complex atoms (hydrogin) into more complex atoms (helium) thereby both increasing complexity and entropy. Yes, there there exists a local increase of complexity but notice next important distinction. If you apply the laws of usual thermodynamics to the star and the rest of Universe, you predict a 'thermal dead' for Universe as a whole (I mean in a very large period of time of cosmological order of magnitude). This is the point of view maintained by Murray Gell-Mann in his famous book /the Quark and the Jaguar/. Gell-Mann thinks that Cosmos complexity is something of an 'accident', a fluctuation in a general tendency to disorder. In that view life would be just an accident, one very improbable. This is very difficult to accept in both technical and philosophical terms. Some people want to explain the observed tendency to order and complexity on the cosmological scale. Stuart Kaufman is one. He claims the need for new laws of thermodynamics. Kaufman introduces a fourth law of thermodynamics would explain life. In that view, life would be not an accident but a consequence of the laws of nature. This is the reason which Kaufman titled his bestseller book with the fantastic title /At home in the Universe/. I think that we, living organism, are at home but I try to explain the observed emergence of cosmological order in basis to recent advances in thermodynamics. --http://canonicalscience.org/en/miscellaneouszone/guidelines.html I think I understand a trifle of what you are saying, Nevertheless I object to "order and complexity". These are subjective terms, that might not scientifically mean anything. In essence entropy (that does have a scientific meaning) increases with time. Nescessarily in has to decrease when we look back in time. As all our observations are actually looking back in time, we nescessarily must observe low(er) entropy. Does Stuart Kaufman explain time? I'll check you link. PS over here in alt.atheism adman is regarded as being kind of stupid. Understanding something, but thinking he knows it all.
