  It is shown that the general scalar tensor cosmologies may explain all the
current cosmological observations without the need of invoking any ad hoc
missing energy density. The explanation is based entirely on the internal
dynamics of the theories. Two important predictions of the present analysis
are: the universe is tending towards a matter dominated state with the
dimunition of the dark energy component and the acceleration of the universe,
if any, is slowing down with time.
