Hamilton's rule reframes altruism as genetic accounting: you'd rather save two siblings (each carrying 50% of your genes) than yourself, because the math of B × R > C is satisfied. This dissolves the paradox of organisms evolving to die for others — from your genes' perspective, relatives ARE you, just spread across multiple bodies. Selfishness and heroism become the same calculation under different numbers.
