The aim of this paper is to investigate and review the research literature in the field of psychological and ethological sciences based upon altruistic behaviour emphasizing its molecular, neuro-endocrionological aspects responsible for its execution in humans and animals. The regions of the brains involved were thoroughly studied about. Also, I am going to review the research based upon various social experiments and molecular biology studies of responses and change in genetic makeup of an altruistic individual as to bring out what brought back such changes and hence sets apart the giving nature. In this paper, I also examined how altruistic behavior helps during uncomfortable situations referring to behavioral and neural evidence that by acting altruistically, painful feelings can be relieved in human performers. The positive altruism has also been referred along with an overview of positive psychology, which is the scientific study of well-being and optimal human functioning. The results and findings of this paper will shed light on the psychological and biological mechanisms underlying human pro-social behavior and provide practical insights into pain management as well.
