entrophy applies to information systems (like DNA). So how exactly does entrophy decrease in information systems to increase to total information. this is what evolution requires. evolution has to generate massive amounts of info in the genome, where does this info come from. especially since no known amount of highly specified information has ever spontaneously produced itself. for particle to man evolution, information has to be generated, and evolution says it comes from nowhere. something from nothing like to see that one live.
I'll tell you the theory of evolution, so you'll understand how information can increase, according to the theory.
a) We take a given organism that is living along just fine from generation to generation with a given set of genes, or genome, as they say. (Note that there is nothing against thermodynamis in this suppostion, it has been observed to happen)
b) We suppose that some mutations come along in the genes for some of the critters in the population. (Note that there is nothing against thermodynamics in this supposition, it has been observed to happen).
c) By chance, a great many of the mutations do nothing for or against the organisms, a great many are actually harmful to the organisms, and a few - precious few - are actually helpful in the overall reproduction of the individuals. (Note that there is nothing against thermodynamics in this supposition, it is implied in the fact that mutations are random)
At this point, the mutations are strictly speaking new information in the genome, but they represent a degredation in the ability of the genome to express what a good, fit organism is.
d) Over time, those individuals saddled with the harmful mutations wind up having fewer descendents, and those individual blessed with the helpful mutations manage to leave more progeny. In this way, "helpful" mutations come to be more and more prominant in the population, even becoming the norm after many generations; bad mutations become less and less prominant, even being weeded out from the population. There is nothing against thermodynamics in this step; we expect slower antelopes to get eaten, faster antelopes to get away, and so forth.
This process represents, finally, a new, enhanced level of information within the genome of the population.
The process can then be repeated over and over. Over geological ages, whole new species arise by this method.
There, that's how the increased information comes along, and you will note that at no step is thermodynamics any kind of problem for the process.
