paper presented at the ESO-IAC Conference on "Quasar Hosts"
Tenerife, 24-27 september 1996

In this paper four questions will be addressed:
(a) Are the best ground based and HST data on quasar hosts in agreement ?
(b) Do radio quiet quasars occur in elliptical galaxies as well as in spirals ?
(c) Are the colours of quasar galaxies on average bluer than typical gE galaxies, indicating that recent star formation has taken place ?
(d) Is the optical luminosity function of radio quasars and strong radio galaxies more or less the same ?
The answer to all questions will turn out to be affirmative. The implications for unified models will be discussed and a scenario for quasar evolution proposed.
