  The shifting of spectral lines due to induced correlation effect, discovered
first by Wolf for the single scattering case which mimics the Doppler mechanism
has been extended and developed further by the present authors known as Dynamic
Multiple scattering(DMS). We have explored DMS theory for explaining anomalous
redshifts in quasars. Our recent work, based on the statistical analysis of the
V\'eron-Cetty data(2003) supports that quasar redshifts fit the overall Hubble
expansion law, as in the case of galaxies, for z less than equal to 0.295 but
not for higher redshifts, indicating clearly the inadequacy of the Doppler
effect as the sole mechanism in explaining the redshifts for high redshift
quasars for z greater than equal to 0.295. We found that the redshift posseses
an additive, discordant component due to frequency shifting from the
correlation induced mechanism which increases gradually for ~ 0.295 < z < 3.0,
however, appearing to follow the evolutionary picture of the universe with
absolute dependence on the physical characteristics i.e., environmental aspects
of the relevant sources through which the light rays pass, after being multiply
scattered.
