How to Calculate Hamilton’s Rule

To understand the calculation of Hamilton’s Rule few terms are important like:

  • Relatedness (r): Relatedness measures how much genetic material two individuals have in common. In simpler words, it’s like looking at how much DNA they share. For instance, siblings usually have about half of their DNA in common, so their relatedness would be expressed as r=0.5.
  • Benefit (B): Benefit is the advantage gained by the one who receives selfless actions. Put simply, it’s what the recipient gets out of the behavior. This could mean better chances of survival, more success in reproduction, or any other positive outcome.
  • Cost (C): Cost refers to the drawback or sacrifice experienced by the individual who acts selflessly. It could mean giving up resources, spending time, or missing out on opportunities.

Once we get the values of r, B, and C one can easily put the values in the formula r B > C to calculate Hamilton’s Rule.

Hamilton’s Rule

Hamilton’s rule, also known as Hamilton’s principle, explains how altruistic behaviours evolve by considering the balance between the benefits to relatives and the costs to the individual. Hamilton’s Rule example is seen in altruistic behaviour in animals, where individuals sacrifice themselves to benefit relatives. This concept helps us understand why organisms, like ants and humans, engage in actions that help others even at their own expense.

It’s a key idea in evolutionary biology, shedding light on the emergence of cooperation and selflessness in populations over time. In this article, we will cover the Hamilton rule, formula, kin selection and more.

What is Hamilton’s Rule?

Hamilton’s Rules state that organisms adapt to encourage genetic success, not individualized reproductive success. In simple terms, the survival of one’s genes is determined not only by the number of offspring a parent has but also by the reproductive success of near relatives. Hamilton’s Rules helps to understand the presence of family systems in nature....

Kin Selection

Kin selection, proposed by biologist W.D. Hamilton in the 1960s, explains how altruistic behaviors evolve based on genetic relatedness. The idea is that individuals are more likely to help close relatives because they share some of their genes. By aiding relatives in survival and reproduction, individuals indirectly promote the spread of their own genes to future generations, even if they don’t directly reproduce themselves....

Conclusion – Hamilton’s Rule

Hamilton’s rule provides a useful way to study how altruistic behaviors evolve in living things. By considering how much genetic material individuals share, along with the benefits and costs of being altruistic, we can understand why creatures collaborate and help each other out in nature. This concept is not just for humans—it applies across the animal kingdom, from bugs to mammals. Understanding these ideas helps scientists unlock the secrets of social relationships and plays a role in keeping Earth’s biodiversity thriving....
