In 2003 A. Nies proved that the free group in two generators is a homogeneous structure. Naturally, one may ask whether free groups in higher rank are homogeneous. In this talk we will present a positive answer to the above question. As a consequence we achieve a description of forking independence in non abelian free groups and various saturated-like properties for these "standard" models. This is a joint work with C. Perin."
