DESCRIPTION:There is mounting evidence that mechanical radio-mode AGN feed
 back is important in galaxy evolution\, and in order to quantify this feed
 back\, detailed models of radio lobe evolution are required.  Self-similar
  analytic models exist for large FRII radio sources but the evolution of t
 he young precursor radio sources is not yet fully understood.  \n\nThis ta
 lk will present a dynamical and radiative model for young source evolution
  (sub-kpc scales) as an extension to existing self-similar models\, and di
 scuss the full model in the context of a sample of nearly 100 radio-loud s
 ources.  Robust knowledge of the host galaxy properties of this sample all
 ow certain evolutionary tracks to be observationally ruled out in a new me
 thod of tracking radio source evolution.\n
