The primitive societies have passed through several stages of economic development everywhere in the world. Thus one finds the stages of food gathering, hunting and fishing, farming, etc. among the Indian tribes.
The tribes living in the forests and hills usually earn their livelihood by means of food gathering, hunting and fishing. Such is the life of Kadar of Kerala, Birhor and Kharia of Bihar and other tribes. The tribes living in dense forests, full of wild beasts, live on hunting. Such are the tribes of Naga, Kuki, Bhil, Santhal and Gond.
