By tracing the origin of sports, we can better understand and develop the sports. The current re-search discusses the origin of the sports through the method of documentary and the method of logical reasoning. This paper puts sports in the earth 4.6 billion years’ evolution of species to discuss its origin in an evolutionary perspective and redefine sports on a broader dimension. Research shows that sports are a process which life changes its fitness of “feel” or “response” through body action. Sports originate between the birth of the perceptual cognition and the rational cognition, and accelerate the progress of human civilization. The origin of sports is not behavioral agent who creates it, but a “byproduct” during the survival game.
