Inclusive fitness later came to be understood as forming a general basis for kin selection theory , which attempts to interpret altruistic social behaviour in animals through genetic relatedness and benefits and costs associated with altruistic acts.
Which theory suggests that altruistic behavior is governed by calculations of benefits and costs?
Inclusive fitness later came to be understood as forming a general basis for kin selection theory , which attempts to interpret altruistic social behaviour in animals through genetic relatedness and benefits and costs associated with altruistic acts.

What is Hamilton’s rule?
Specifically, Hamilton’s rule states that the change in average trait value in a population is proportional to BR−C . This rule is commonly believed to be a natural law making important predictions in biology, and its influence has spread from evolutionary biology to other fields including the social sciences.
What do you mean by kin selection?
Kin selection, a type of natural selection that considers the role relatives play when evaluating the genetic fitness of a given individual . ... Kin selection occurs when an animal engages in self-sacrificial behaviour that benefits the genetic fitness of its relatives.
What is Hamilton’s rule of kin selection?
The central explanatory principle of kin selection theory is Hamilton’s rule, which says that a gene coding for a social behavior will be favored by natural selection if and only if rb > c, where b represents the benefit that the behavior confers on the recipient, c represents the cost that it imposes on the actor, and ...
What are 2 examples of altruism?
- Doing something to help another person with no expectation of reward.
- Forgoing things that may bring personal benefits if they create costs for others.
