Origin of life and that second law of thermodynamics
This article (subscription req'd) in Science magazine by P.G. Falkowski and Y. Isozaki (24 October 2008) is a perspective on the origin and cycling of free oxygen on Earth. It's a brief, good description of an important geochemical cycle. But what struck me as particularly notable was the ending paragraph, which begins
Each mole of oxygen in Earth's atmosphere required ~450 kJ equivalents of photon energy to produce.This leads to a very clear refutation of one of the Creationists' favorite, hoary arguments. The paragraph ends
Nature certainly has provided an incredible source of potential energy for the evolution of life on Earth.Thank you.
