Evolution has to do with DNA which is constant and independent of energy
Oh, you couldn’t be more wrong, RU. Life IS energy.

Evolution is already a proven fact. The theory of evolution, as I have mentioned earlier in this thread (as well as in others) is merely in regards to the engine that drives evolution, ie: Natural Selection, Punctuated Equilibria, etc. Perhaps the common references to "Darwin's theory of evolution..." produces and promotes this misconception, when in fact he put forth the theory of evolution by means of natural selection.
Let's be specific here. Microevolution is proven. Macroevolution (specifically trans-speciation) is far from proven.
I must confess, I was baiting with my question regarding the second law of thermodynamics. I have absolutely no doubt that life does not violate the second law. I am attempting to illustrate a point, specifically because many of the posters here not only view macroevolution as a foregone conclusion, but appear to believe that any question against it is an unreasonable argument against science, and an obvious demonstration of total ignorance. There is a definite arrogance on this thread.
I challenge that assertion. Need I bring up the premise of ‘spontaneous generation’, which existed among scientists of previous generations? History has shown that if the scientific establishment thinks enough of you to label you a “maverick” (or the medical community labels you a ‘quack’), they are putting you in the same honorable category as: Dalton, the father of chemistry (for his atomic theory), Semmelweis, father of hygiene, who fought (vainly) to save the lives of thousands of women dying from childbed fever (because then the medical community agreed that believing in something you can’t see was the equivalent of believing in spooks), Pasteur, and Albert Einstein (among a plethora of others). Today, any scientist daring to challenge macroevolution is considered a maverick quack, regardless of his/ her explanation. Period.
I asked a direct question…and received many different responses. One brought forth a confusion between the second law and the law of conservation. Another reasoned that a match cannot be relit, sort of confusing the second law with a chemical reaction (or something), the third brought forth a link proving my point:

This argument derives from a misunderstanding of the Second Law. If it were valid, mineral crystals and snowflakes would also be impossible, because they, too, are complex structures that form spontaneously from disordered parts.
The Second Law actually states that the total entropy of a closed system (one that no energy or matter leaves or enters) cannot decrease. Entropy is a physical concept often casually described as disorder, but it differs significantly from the conversational use of the word.
More important, however, the Second Law permits parts of a system to decrease in entropy as long as other parts experience an offsetting increase. Thus, our planet as a whole can grow more complex because the sun pours heat and light onto it, and the greater entropy associated with the sun's nuclear fusion more than rebalances the scales. Simple organisms can fuel their rise toward complexity by consuming other forms of life and nonliving materials.
Snowflakes (and other solids) form when energy leaves the environment. If the assumption is made that the second law isn’t being violated because energy is being added to the system (thus rebalancing the scales to provide for more order in other parts of the environment), doesn’t that fall short as an explaination? If energy is poured into a system, it should INCREASE the entropy of that overall system, not create a stationary entropy environment.
According to this source, the energy is going into the system causing increasing entropy in some parts while decreasing the amounts of entropy in others. New species are forming, with increasing complexity, because although some parts are gaining entropy, others (the living species) are losing it at an equivalent rate….
I accepted that as reasonable explanation until yesterday, when I read some branch off of a link provided by Nileriver on a different thread:
http://www.entropylaw.com/This is, by far, a much better explanation of our environment adhering to the second law of thermodynamics. Apparently (to be brief, because it is a good but long article), the supposition is made that entropy IS in fact, increasing within the system. Life is increasing complexity driven by the need for a more efficient means of maximizing entropy in the system. IOW…the living entities themselves are creating the entropy (through increased aerobic capacity, oxygen flow being released into the environment, capacity to move, thought process, ect.)
So…are the organisms themselves increasingly entropic in nature (as the second article would indicate), or is it the environment becoming more entropic? I would go with something in between, leaning towards the first argument. This requires a slight expansion of the second law of thermodynamics.
QUOTE
The system will select the path or assembly of paths out of otherwise available paths that minimizes the potential or maximizes the entropy at the fastest rate given the constraints.
If the world selects those dynamics that minimize potentials at the fastest rate given the constraints, and if ordered flow is more efficient at reducing potentials than disordered flow, then the world will select order whenever it gets the chance. Theworld is in the order production business because ordered flow produces entropy faster than disordered flow
Now, isn’t that interesting? The first explanation indicated a different concept entirely…decreasing entropy for life, within an increasingly entropic environment with shifting distributions of energy throughout. I am not familiar with the explanation of the day, but this serves to indicate that many of the assertions for macroevolution are not agreed upon within the scientific community, yet both are offered on these sites as legitimate unadulterated (unquestionable) proof. The distinction is important to me because both concepts are asserted with authority, indicating a clear prejudiced outcome, which leads me to question the validity of other assertions within the field of evolutionary study as well.
Evolution might be the best scientific theory we have, but it certainly isn’t infallible. Many of the arguments in favor of macroevolution aren’t very dissimilar to arguments in favor of a Creator (space aliens, or whatever else you want to believe). Macroevolution simply substitutes the word ‘time’ for ‘God’…such as, 'with enough time anything is possible'… and requires the viewer to take a leap of faith and believe a concept which is beyond the human mind’s capacity to understand (both God and infinity-which evolution prefers to call 'a long long time'... are beyond our perceptions)
It could go either way with me. I have no fixation on proving Creationism (who could? It is an entirely faith based concept), and I believe some of Genesis is a myth used to explain our creation to a very simple people. There is too much "entropy" in my household, honestly, for me to form an intelligent debate on the details of the subject-matter. I am specifically challenging the know-it- all assertions here. We DO NOT, in fact, know it all.
