Altruism benefits recipient at cost to actor, reducing direct fitness but increasing indirect fitness via relatives sharing genes. Hamilton's rule rb>c predicts altruism evolves when relatedness times benefit exceeds cost. Relatedness 0.5 for siblings, 0.25 for half-sibs, 0.125 for cousins, 0.75 for haplodiploid sisters explains worker sterility in Hymenoptera. Inclusive fitness includes direct plus indirect components. Eusociality, alarm calls and reciprocal altruism exemplify. Hence Kin selection captures kin selection logic underlying altruistic behavior. This concept integrates genetics, e

rb − c > 0 reflects key principle in quiz on behavior pyqs solved-section f, where evolutionary mechanisms shape genetic variation and adaptation. In this context, rb − c > 0 aligns with experimental and theoretical evidence from population genetics, behavioral ecology and molecular phylogeny. Textbooks like Campbell Biology, Futuyma Evolution and Hartl Principles illustrate supporting data. Understanding why rb − c > 0 fits helps integrate natural selection, drift and species concepts essential for NEET, CSIR-NET and GATE examinations. This concept integrates genetics, ecology and molecular e
