"Evolution violates the 2nd law of thermodynamics."
This shows more a misconception about thermodynamics than about evolution. The second law of thermodynamics says, "No process is possible in which the sole result is the transfer of energy from a cooler to a hotter body." [Atkins, 1984, The Second Law, pg. 25] Now you may be scratching your head wondering what this has to do with evolution. The confusion arises when the 2nd law is phrased in another equivalent way, "The entropy of a closed system cannot decrease." Entropy is an indication of unusable energy and often (but not always!) corresponds to intuitive notions of disorder or randomness. Creationists thus misinterpret the 2nd law to say that things invariably progress from order to disorder.
However, they neglect the fact that life is not a closed system. The sun provides more than enough energy to drive things. If a mature tomato plant can have more usable energy than the seed it grew from, why should anyone expect that the next generation of tomatoes can't have more usable energy still? Creationists sometimes try to get around this by claiming that the information carried by living things lets them create order. However, not only is life irrelevant to the 2nd law, but order from disorder is common in nonliving systems, too. Snowflakes, sand dunes, tornadoes, stalactites, graded river beds, and lightning are just a few examples of order coming from disorder in nature; none require an intelligent program to achieve that order. In any nontrivial system with lots of energy flowing through it, you are almost certain to find order arising somewhere in the system. If order from disorder is supposed to violate the 2nd law of thermodynamics, why is it ubiquitous in nature?
The thermodynamics argument against evolution displays a misconception about evolution as well as about thermodynamics, since a clear understanding of how evolution works should reveal major flaws in the argument. Evolution says that organisms reproduce with only small changes between generations (after their own kind, so to speak). For example, animals might have appendages which are longer or shorter, thicker or flatter, lighter or darker than their parents. Occasionally, a change might be on the order of having four or six fingers instead of five. Once the differences appear, the theory of evolution calls for differential reproductive success. For example, maybe the animals with longer appendages survive to have more offspring than short-appendaged ones. All of these processes can be observed today. They obviously don't violate any physical laws.

Funny that
my philosophy teacher who is very heavily Christian, and also a physict, tells me, no matter how much he disbelieves evolution, it is a self-evident truth.
Evolution is as proven as pretty much any other theory.
We have seen plenty of mammal change. Rats in New York have evolved to 30% larger than normal rats, as part of the process of natural selection.
I do not see how the laws of themal dynamics have anything to do with this in any sense?
I am trying to find this certain speices of bird, which people have seen evolve over it's journey around Britian -> America -> Britian to such a degree that once the 'flock' has made the journey it will be unable to breed with the original flock.. I cant rememebr what it is though, so still looking.
Evolution is a very logical and self-evident process. It's just that people were so god-fearing they chose to ignore the obvious
Plus when I walk down the street, I'm sorry, but I don't look at an ant and see my long lost relative, or observe a wilted plant and get sad because I'm related to it. It's really ridiculous. What really gets me, is critics of the bible always are like, "you mean we all came from two people? HA! Yeah right!" Yeah, well look at your own little belief. "You mean we, and every bug, fungus, animal, and plant came from one or a couple of spontaneous cells?!" I know which one makes more sense to me.

Which ever theory you choose to believe in - evolution or creation or alien transplant, whatever - they are all just theories and until scientifically proven should not be tought in school unless they are presented as just that - theories. In fact, teaching evolution as a "theory" and not a fact would actually serve to encourage students to think and investigate and maybe one day prove it or come up with a new theory. But the bottom line is schools should stick to teaching facts, not deceiving children into believing a theory just because it is the only one they can come up with at the time.
By the way - rats getting bigger is a result of adaptation not evolution. Now if rats grew antennas or wings that might serve as evidence of evolution.

I'm sorry, but evolution has not been proven and will NEVER be TRUE science no matter how many people want to think it is science. Do you know what science is? In order for something or a field of study to become science, one must be able to experiment with it in controlled lab environments.
If one cannot run tests and experiments and simulate the subject in question, then, by definition, it doesn't fall into the realm of science.
The problem with the theory of evolution is the fact that it neds millions upon millions of years to work. Therefore, no one can confine something of evolution to a lab and simulate it to obtain data and to isolate variables and come to conclusions.
But why doesn't this same principle work in terms of more dramatic change, like a species transforming into a new?
So my point is, is that the first eye could not have come into being through small little parts, simply because for any benefit to exist, the whole system woiuld have to be all the sudden present and functioning.
This is only one argument out of many good ones.
...plus we don't have any evidence of interspecies transformation[/qupte]
Sure we do. See the other messages.
plus the fact that we cannot simulate evolution in controlled environments
We are constantly creating new species and for years we have bred new species. Most of your food has been bred from older strains into new species.
What really gets me, is critics of the bible always are like, "you mean we all came from two people? HA! Yeah right!"
Actually, we do believe that there was a first creature that was clearly identified as homo sapiens. We just don't believe it suddenly emerged from dust.
