Kin selection theory explains altruism in an 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.

W. D. Hamilton has proposed a mathematical expression for the kin selection:
"where B is the benefit to the recipient, C is the cost to the altruist (both measured as the number of offspring gained or lost) and r is the coefficient of relationship (i.e. the probability that they share the same gene by descent)."[9]

An experiment conducted in Britain supports kin selection[9] The experiment is illustrated by diagrams below. The result shows that people are more willing to provide help to people with higher relatedness and occurs in both gender and various cultures. The result also show gender difference in kin selection which men are more affected by the cues of similar genetic based than women.
