Evolution and Entropy
Of all the stupid things creationists say about evolution, I think the one that most annoys me is this:
The simple fact is that the law of entropy precludes macro-evolution from ever occurring. Entropy is the measure of increasing disorder in a system. The natural (or spontaneous) tendency of matter and of all of energy is toward greater disorder -- not toward greater order or complexity as evolution would teach.
As mentioned here, this argument shows ignorance of thermodynamics as well as of evolution. Entropy applies only to a closed system. The evolution of life on earth is not a closed system.
To put it another way: If the fundamental teachings of biology and the fundamental teachings of physics were mutually exclusive, wouldn't scientists have noticed?
