Abstract: In the present paper we study the evolution of a homogeneous and anisotropic Kantowski Sachs cosmological model coupled with radiation and a generalized Chaplygin gas. Our main objective is verifying if this model evolves to a homogeneous and isotropic Friedmann Robertson Walker cosmological model, which is the more accepted model to describe our present Universe. If this is the case, we may imagine that the Kantowski Sachs cosmological model could had been an early stage of our Universe.
