Hamilton's rule states that natural selection favors altruistic behavior when the benefits to the recipient, valued by the degree of relatedness, outweigh the cost to the altruist. This means that altruistic behavior is more likely to be favored if the recipient is a close relative, such as a sibling or offspring, rather than a distant relative or unrelated individual. The rule also implies that altruistic behavior that causes the death of the altruist is unlikely to be favored by natural selection.
