Helping behavior refers to voluntary actions intended to help the others, with reward regarded or disregarded. It is a type of prosocial behavior (voluntary action intended to help or benefit another individual or group of individuals, such as sharing, comforting, rescuing and helping).
Altruism is distinguished from helping behavior. Altruism refers to prosocial behaviors that are carried out without expectation of obtaining external reward (concrete reward or social reward) or internal reward (self-reward).
Kin selection theory explains altruism in evolutionary perspective. Since natural selection aids in screening out species without abilities to adapt the challenging environment, preservation of good traits and superior genes are important for survival of future generations (i.e. inclusive fitness). Kin selection refers to the tendency to perform behaviors that may favor the chance of survival of people with similar genetic base.
WD Hamilton has proposed a mathematical expression for the kin selection:
