Each living life is attached in culture whether humans or animals. Culture is natural development during birth process {what we call is behavior, that changes from individual to individual broadened when lives in family that family is part of a society (group or community), behavior of the group is culture} and its evolution is based on intelligence reaction to experiences and needs. For example initial stages of humans, behavior were similar to other animals lived in groups. Animals too live in groups (society or community) and their group behavior and practices is their culture. Human intelligence reacted stronger to experiences and needs that widened cultural status.

 

Culture is process to live in group. Each society has norms to follow by individuals in order to retain society strong and intact.

 

Culture is a process for identity of living creatures and cultural evolution raises the identity of society, benefit goes to its individuals.

 

Culture differentiates from group to group (as behavior changes) though major part remains same as human culture to differentiate from other species. This gives different identity.

 

For society’s culture there is one individual behind who broadens or establishes the cultural status.

 

Culture developed by beliefs, faith, practices, customs, way to live, art, intelligence, language, food habits, and economy etc; Cultural growth gave identity to the societies that named,  Christian or Muslim or Hindu or Jewish or Buddhist etc; have different cultures. So when we come across art, customs etc; we identify what is their culture or which religion they belong. Cultural growth is community growth.

 

Differences of cultures of two societies when clash leads to war and stronger one overpowers the other to establish own culture that way it broadens its culture. An apparent example we have is western culture spread in most part of the world.
