In Animal Choice and Human Freedom: On the Genealogy of Self-Determined Action, Michael Yudanin argues that describing freedom conceptually is impossible without explaining how it can exist in the world. Yudanin develops an account of freedom's instantiation in biological agents and provides several prerequisites that are necessary for its exercise. He demonstrates that freedom is linked to the form of life and distinguishes between choice in non-verbal animals and human freedom, where the latter is enabled by the development of language and thus possesses a distinct character. Following this descriptive account, Yudanin explores freedom's evolutionary history, explaining how it developed in the course of the evolution of species.
