According to a published paper of Dr. Rafi-ud-Din, referred to earlier in this monograph, the period from the creation of Adam down to the present day can be taken generally as the period of conceptual or ideological evolution. However, in all humility and modesty, I beg to differ from him here and dare to present a more analytical, detailed and deeper view of humanity’s evolutionary process. I believe that the first stage of evolution consisted of purely physico-chemical changes and mutations. And the second level or stage of evolution, i.e. the biological evolutionary process, has already passed through two stages of evolution; while the third stage is presently under way.
