“...there are no known violations of the second law of thermodynamics. Ordinarily the second law is stated for isolated [closed] systems, but the second law applies equally well to open systems ... there is somehow associated with the field of far-from equilibrium phenomena the notion that the second law of thermodynamics fails for such systems. It is important to make sure that this error does not perpetuate itself.”
[Dr. John Ross, Harvard scientist (evolutionist), Chemical and Engineering News, vol. 58, July 7, 1980, p. 40]
No, it isn't, it is an example that relates to concepts that you need to understand. The reactions that lead to the assembling of snowflakes are the same type of reactions that lead to the formations of complex molecules which leads to the formation of life. That several of these reactions occur leads to the conclusion that it is extremely likely that other reactions will occur as well, including the reactions that lead to the evolution of life forms.
