What Does Hamiltons Rule Rb C Tell Us

Hamilton’s rule shows that the former process will occur when rb > c—the benefits to the recipients of an altruistic act b, weighted by the relatedness between the social partners r, exceed the costs to the altruists c—drives altruistic genotypes spreading against nonaltruistic ones.

What does Hamilton's rule RB c predict?

Hamilton’s rule predicts that each social action arises only under certain combinations of values of r, b and c [7,9]. Factors bringing about the required values of r, b and c within natural populations create conditions for social evolution.

What does Hamilton's rule tell us RB c0?

What does Hamilton’s rule (rb − c > 0) tell us? When relatedness is high, benefit to the recipient is high, and cost to the actor is low, then natural selection should strongly favor individuals that help their kin.
