  We analyse the unreduced, nonperturbative dynamics of an arbitrary many-body
interaction process with the help of the generalised effective potential method
and reveal the well-specified universal origin of change (emergence), time and
evolution in an a priori conservative, time-independent system. It appears
together with the universal dynamic complexity definition, where this unified
complexity conservation and transformation constitutes the essence of
evolution. We then consider the detailed structure of this universal
evolutionary process showing its step-wise, "punctuated" character, now
provided with the exact mathematical description. Comparing the expected
features of a revolutionary complexity transition near a step-like complexity
upgrade with the currently observed behaviour of world's social and economic
systems, we prove the necessity of complexity revolution towards the superior
civilisation level of well-defined nature, the only alternative being an
equally dramatic and irreversible degradation, irrespective of efforts applied
to stop the crisis at the current totally saturated complexity level.
