Many dynamic models for evolution are Markovian and have "a free fitness function", which monotonically increases with time and takes its maximum at the evolutionary equilibrium. Free fitness is the logarithmic fitness plus entropy. Application to (1) molecular evolution model and (2) quantitative genetics are explained, and (3) population genetics and (4) an ecological succession model are briefly mentioned. Evolutionary dynamics are mathematically equivalent. to statistical thermodynamics.
