I'm not quite sure where to put this, in Physics or Biology. Mentors, please move this to the most appropriate location. A common argument put forth by creationists/intelligent design proponents is that evolution/abiogenesis violates the second law of thermodynamics, by causing a decrease in entropy. Of course we know this argument is ridiculous, as any local decrease in entropy on Earth is more than balanced by an increase in entropy in the Sun. I was thinking though, does evolution/abiogenesis even cause a local decrease in entropy? I have never seen it proven. If anyone knows the answer/can link to a proof either way let me know. PS. I do not want to discuss creationism/intelligent design, or their argument that evolution violates thermodynamics, as these topics are a violation of the guidelines. Please keep the discussion on topic about whether or not evolution and abiogenesis are a local decrease or increase in entropy, thank you.
