Cosmic evolution is the scientific stuy of universal change. It is an intellectual framework that offers a grand synthesis of the many varied changes in the assembly and composition of radiation, matter, and life throughout the history of the universe. While engaging the time-honored queries of who we are and whence we came, this interdisciplinary subject attempts to unify the sciences within the entirety of natural history—a single broad scientific narrative of a possible origin and evolution of all material things, from an inferred big bang to humankind. (Closely related subjects include epic of evolution, big history, and astrobiology).
