     Thus, the stages of human civilization have been three, viz., the hill-stage, the pastoral stage, and the agricultural stage. When vocations multiplied, the fishermen folk moved from towns and cities to the littoral and settled there. As the tract lying between the hilly region and the pastoral region becomes dry and turns into a desert during hot summer, the inhabitants of such parts had to resort to highway robbery and plunder for their subsistence.

      In this way, the habitable part of the Tamil country became naturally divided into five regions, viz., the hilly region, the pastoral region, the agricultural region, the littoral and the dry region, which have been named KuŠinji, Mullai, Marudam, Neydal, and Pƒlai respectively, after their characteristic flora, by the original Tamil grammarian.

      The physiographical features of Lemuria were exactly of the same nature as those of modern Tamil Nadu, and the two gigantic rivers, Pahru˜i and Kumari, flowed west to east at the southern and northern border of the submerged land respectively.

Where this Evolution first took place

      “The five sub-divisions of the habitable regions occur contiguous to each other and in a small fraction of the earths’ surface in India south of the Vindhyas. It is therefore easy to understand how increase of population and alterations in the natural supply of food-stuffs brought about here at different periods the migration of men from region to region and the consequent development of the different stages of human culture, the hunter, the nomad, the pastoral, the coastal,and the agricultural, due to the differing stimuli provided by the changing milieu; in other words, the geographical control of the growth of human civilization can be worked out and set forth clear as on a map by a study of man's progress in this restricted portion of the surface of the earth outside India, these five natural regions occur on a vast scale, e.g., the Mullai the vaste steppe land extending from the Carpathians to the foot hills of the Altais, the KuŠi½ji or the great mountain chain from the Pyrenees to the Himalayas and beyond, forming a grand girdle round the waist of mother earth, the
