"One of the oldest canards in the creationists' book is the claim that evolution must be false because it violates the second law of thermodynamics...

..., or the principle that, as they put it, everything must go from order to disorder."

[via NewScientist by way of NewScientist]

The idea is defended with some astute mathematical comparisons, culminating in:

"To spell it out, there's about a trillion times more entropy flux available than is required for evolution. The degree by which earth's entropy is reduced by the action of evolutionary processes is miniscule relative to the amount that the entropy of the cosmic microwave background is increased."

In fact, a recent modeling effort intended to illustrate the possibilities of life spontaneously erupting from primordial soup determined that "[w]ithout the ability of tRNAs to discriminate between various amino acids, such a random system might not be able to self-assemble into a highly organized code capable of supporting life." "They found that the properties of the molecules set the concentrations at which the molecules needed to exist for a coded regime to emerge."
