  As Nature's version of machine learning, evolution has solved many
extraordinarily complex problems, none perhaps more remarkable than learning to
harness an increase in chemical entropy (disorder) to generate directed
chemical forces (order). Using muscle as a model system, here I unpack the
basic mechanism by which life creates order from disorder. In short, evolution
tuned the physical properties of certain proteins to contain changes in
chemical entropy. As it happens, these are the "sensible" properties Gibbs
postulated were needed to solve his paradox.
