Human beings is the social animals and human beings stand out as distinct species. Human beings claim man alone has a soul, has higher level of intelligence, has a speaking ability, has sociability and hence civilized from the sociological point of view this uniqueness can be attributed to the sole factors of culture. Culture includes all modes of thought and behaviour and all kinds of material or non-material achievement of man that are handed down from one generation to another through language. Study of culture involves on the study of human society. The difference between marriage and mating : legitimacy and illegitimacy; authority and dominance can be understood only with cultural interpretations. Most of the sciences of man ( the so called humanistic science ) are actually the science of culture. Man's political, economic, educational, occupational and such other activities are all influenced by culture. The social sciences are devoted to the study of mental and not physical phenomena. " From the sociological point of view the physical objects are products made possible only by transmission of principles and ideas from person to person ".
The Basic Feature of Society : Man is a social animal and he always lives in society. Human society, in comparison with societies, is unique in several respects. Some characteristics of human or animal is societies are as follows :-
The emergence of society can be considered to be a great step in organic evolution. But it is a step taken by only some species and not yet all. Thus the analogy must be understand only as an analogy and not as an identity.
2. The need for Specialisation : Group co-operation among members pre supposes the idea of division of labour and specialisation. The degree of specialisation may differ from society to society.
3. The Need of Solidarity : Societies must guarantee some mode of contact between the members and provide for some motivation for such content. Social solidarity or cohesiveness in the group would be found.
4. The Need for Reproduction : The society or the group must be able to perpetuate its structure, and character. There must be provision for the continuity of the social system even beyond the life-span of any one individual or generation. This is possible only when there is provision for the members to reproduce their kind.
From above it is clear that any kind of society requires certain conditions for its existence. The members of a group or society may not realise them always and strive for their requirements.
# Heredity, the main trait of Bio- Social System
The non- human social system meets its basic needs mainly through the mechanisms that are determined by heredity. Here a change in the social order is possible only from the change in the germ plasma. The society is in the grip of organic evolution. It is biological in character and hence the name 'bio- social system'. Kingsley Davis has carried on his discussion of bio- social system and socio- cultural system at three levels :-
# Culture the Greator of Gaulf Between Human Beings and Primates.
The Homo Sapines, the high minded type of primate has a clear edge over other primates for it has facility of cultural. Society is bio- socio- cultural. It can be referred to as ' socio- cultural ' or in simply as ' human society '. According to Kingsley Davie's, culture provided the sole explanation for the marked differences that we find between human society on the one hand and non- human society, on the other. Hence he calls the human social system " Socio- Culture System ". The dominant role of culture in the socio- cultural system are as follows :-
