Culture tends toward integration

Dhruv Tanwani has observed that

there are so many features of cultural complex ,like it is learned behavior transfers from one generation to another and its integrated nature .some call it adjustive and accommodating nature's .It is human nature that whenever he resides or settled ,he has to adjust according to available sources and things. For example Indians in India are very fussy about their caste feeling. But same Indian if settled down in different country,he prefer to have friendship with any Indian.Even where there is no Indian he does friendship to natives of that country. so this is because of integration nature of his culture.
