The principles of evolution place emphasis on survival of the fittest, which theoretically should prevent one from behaving in a manner that benefits others at one’s own expense. However, the evolutionary value of altruistic behavior can be traced back to primitive times, where helping others was advantageous for families and groups as a whole. According to evolutionary theory, altruistic behaviors should be less frequent in modern society, where group dynamics and relationships are no longer essential for survival. However, the fact that altruistic behavior is still so prominent today suggests that these behaviors contribute to the well-being and survival of mankind as a whole.
