Scientific definitions for altruism
Instinctive behavior that is detrimental or without reproductive benefit to the individual but that favors the survival or spread of that individual's genes. The willingness of a subordinate member of a wolf pack to forgo mating and help care for the dominant pair's pups is an example of altruistic behavior. While the individual may not reproduce, or may reproduce less often, its behavior helps ensure that a close relative does successfully reproduce, thus passing on a large share of the altruistic individual's genetic material.
