This paper reviews current work on the evolution of a differentially rotating solar model. Although we discuss global features of the evolution with rotation in general terms, the specific models described are those computed with the new Yale Rotating Evolution Code (YREC). YREC uses the Kippenhahn and Thomas (1970, KT) formalism as implemented by Endal and Sofia (1976), although the numerical formulation of our code is totally new. Particular calculations that we describe include the effects of different initial total angular momentum, the consequences of varying the properties and magnitude of angular momentum losses by wind torquing, and the consequences of specific composition and angular momentum redistribution mechanisms. This paper is a progress report which points out the complexity of the problem, and the need for a broad-based observational program to solve it. Because the final solution is not yet in hand, we outline the steps that, in our estimation, need to be undertaken in order to make progress.
