We discuss the evolution of clustering of galaxies back to z 2. For that purpose we use the VIMOS-VLT Deep Survey (VVDS) data. We analyze the evolution of the projected two-point correlation function for the global galaxy population and for particular galaxy classes, with different intrinsic luminosities, spectral types, colors and other properties. For the brightest galaxies (with L>L*), for instance, the shape of the correlation function deviated from the power-law much more strongly at z 1 than it is observed now. This finding can be interpreted e.g. in the framework of Halo Occupation Distribution models (HODs) and implies a significant change in the way luminous galaxies traced dark-matter halos at z 1 with respect to now. Our observations represent an important constraint for models trying to reproduce the evolution of galaxy clustering.
