Free energy is energy available to cause continuing change in the system.
This is the Second Law of Thermodynamics. The origin of living cells from non-living chemicals is said to begin with a process referred to as chemical evolution. Chemical evolution is supposed to be a natural process which from disordered and simple molecules gradually produced increasingly complex sets of integrated chemical reaction systems and more complex molecules. Finally there resulted complex living cells that require much information for their description and contain much free energy. Therefore, it appears that chemical evolution contradicts the law of increasing entropy.
