Constructing animal locomotion from new thermodynamics theory

A thermodynamic approach is used to predict the complex features of animal design. Evidence is given that if evolution were rewound, and if runners, swimmers and fliers appeared again, the process should consistently produce the same types of speeds, and stroke-stride frequencies and force outputs for these forms of locomotion as exist today. The theory could even be used to predict how these features would evolve on other planets with different gravitational forces and densities of the gaseous and liquid environments.
