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
(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.
