Rituals:
The social life of the earliest human groups or tribes revolved around food gathering. To begin with, they must have collected anything they could eat-seeds, nuts, fruits, roots. honey and any small animals that could be caught with bare hands. The largest food sharing unit tended to concenuate upon a certain food which was easily available to them in plenty. Thus, human groups eating one type of food came to consider themselves as 'kins' or fellow beings of the same community or clan. Other human groups who ate different foods were not in the kinship, and at first were not even considered human. As we have told you earlier, this special food item is called "totem". The act of gathering the totem was associated with special rituals The rituals sometimes involved sacrifices (including human sacrifice) to secure increased food supply. The food gathering tribes were entirely dependent on nature for their survival. Therefore, in order to avoid scarcity, they also developed certain "taboos". For instance, taboos were enforced on sexual intercourse in order to control their population for the limited supply of food. Attempts were also made to control the group population by a taboo on cohabitation within the totem clan, and by the practice of marriage outside the clan.
