The structures of human behaviours-inspite of all complexities and differences-are not infinite, but are orderly and requlated, and can be considered universal. On the other hand, as human behaviours are formed not only by biological elements, but also by historical and cultural components, and therefore are not randomly created. Behavioural similarities in human beings and their structured forms, may be covered through their variations in the appearances.
