People's attitudes are determined more by their immediate situation or surroundings than by any internal characteristic

Man is a product of evolution. The transformations that immediate situations and surroundings forced on man’s ancestors have given birth to him. So tracing this history of mankind, it is obvious that this characteristic to keep transforming based on situations has been consistently evident and will continue to influence the latest species that evolution has produced. So this attitude to transform is the intrinsic nature of people rather than attitude varying based on internal characteristic.
