New things and new situations that each group had to adjust itself with, needed new words to be coined to name the new objects. These new names peculiar to each group, put together brought forth a separate language of each group as its own, according to the needs peculiar to it, quite different from that of the others.

The lack of the means of conveyance and communication, with the natural barriers of high mountains, the deep seas, the wide rivers, the vast plains and the dense forests full of wild beasts, was not helpful for easy and frequent visits between the different groups settled afar from each other.

Gradually with the passage of time, the groups of the members of one and the same human family, got permanently separated into different units by themselves, separating each other by virtue of the differences in their physical features, complexion, language, dress and the ways of living.

To identify itself, distinguishing and differentiating from the others, each group got itself known by a particular name like the Aryans, the Mongolians, the Semites, the Dravidians, the Saxons, and with the various other names as the different tribes in Africa and elsewhere have chosen for themselves. As time passed on, each group began priding over the other and looking down upon them, with its own fanciful distinctions.

Thus gradually the universal family interest got divided into group interest, and this sectional feeling developed into group selfishness which generated group quarrels and tribal wars which separated the various groups from each other further more. Each group got interested in destroying the other group altogether, to own their properties and to kill or capture the men, women and even the children to serve them, or to make money by selling them to the others as slaves.

Thus started the shedding of the blood of the human family by its own members. With the dissensions getting more and more intensified, the hatred between the groups becoming deeper still, the gulf of the differences separating each other becoming wider and wider, and each group losing its interest in the other, the feeling of mankind belonging to one and the same family was altogether lost, and each group treated the other as the alien one, unknown to it, without any bonds of affinity at all.

Thus man became the enemy of man, and lived a beastly life in the jungles he occupied, each group preying upon the other.
