More over this series which can be traced back to (2) million years ago. as estimated by scholars also witnessed many changes as far as human physical and intellectual activities are concerned. More remarkably in this series glacier formation has occured in the northern part of the globe. This series was long enough to be divided into four glacial series: Gunz, Mindle, Riss and Wurm. It is characterized by severe coolness. It was punctuated by many inter-glacial Series in which the glacier thawed and heat temperature rose. Consequently these inter-glacial series had direct effect on the climate and on the flora and funa.
