Dynamical families in the Galactic globular cluster system

The Halo Galactic Globular Clusters (GCs) lying inside the solar circle (\inn, \r $ -0.8$). We present here both observational evidences and theoretical simulations supporting the hypothesis of a {\it primordial} origin for such correlations and of an {\it environment-induced} destruction of them if absent. In particular, this hypothesis lead us to argue that \inn Halo GCs have undergone a chaotic, environment-driven, dynamical evolution not shared by the \dis GCs though the radial zone of the Galaxy occupied by the two groups is nearly the same.
